+PyRtAudio - a python wrapper around RtAudio that allows to perform audio i/o operations in real-time from the python language.
+
+By Antoine Lefebvre, 2011
+
+This software is in the development stage. Do not expect compatibility
+with future versions. Comments, suggestions, new features, bug fixes,
+etc. are welcome.
+
+
+This distribution of PyRtAudio contains the following:
+
+- rtaudiomodule.cpp: the python wrapper code
+- setup.py: a setup script use to compile and install PyRtAudio
+- examples: a single PyRtAudioTest.py script
+
+INSTALLATION
+
+The compilation and installation of the PyRtAudio module is handled by
+the python Distribution Utilities ("Distutils"). Provided that your
+system has a C++ compiler and is properly configure, the following
+command should be sufficient:
+
+>> python setup.py install

+
+The RtAudio API incorporates many of the concepts developed in the <A href="http://www.portaudio.com/">PortAudio</A> project by Phil Burk and Ross Bencina.  Early development also incorporated ideas from Bill Schottstaedt's <A href="http://www-ccrma.stanford.edu/software/snd/sndlib/">sndlib</A>.  The CCRMA <A href="http://www-ccrma.stanford.edu/groups/soundwire/">SoundWire group</A> provided valuable feedback during the API proposal stages.
+
+The early 2.0 version of RtAudio was slowly developed over the course of many months while in residence at the <A href="http://www.iua.upf.es/">Institut Universitari de L'Audiovisual (IUA)</A> in Barcelona, Spain and the <A href="http://www.acoustics.hut.fi/">Laboratory of Acoustics and Audio Signal Processing</A> at the Helsinki University of Technology, Finland.  Much subsequent development happened while working at the <A href="http://www-ccrma.stanford.edu/">Center for Computer Research in Music and Acoustics (CCRMA)</A> at <A href="http://www.stanford.edu/">Stanford University</A>.  All recent versions of RtAudio have been completed while working as an assistant / associate professor of <a href="http://www.music.mcgill.ca/musictech/">Music Technology</a> at <a href="http://www.mcgill.ca/">McGill University</a>.  This work was supported in part by the United States Air Force Office of Scientific Research (grant \#F49620-99-1-0293).

+RtAudio is designed to provide a common API across the various supported operating systems and audio libraries.  Despite that, some issues should be mentioned with regard to each.
+
+\section linux Linux:
+
+RtAudio for Linux was developed under Redhat distributions 7.0 - Fedora.  Four different audio APIs are supported on Linux platforms: <A href="http://www.opensound.com/oss.html">OSS</A> (versions >= 4.0), <A href="http://www.alsa-project.org/">ALSA</A>, <A href="http://jackit.sourceforge.net/">Jack</A>, and <A href="http://www.freedesktop.org/wiki/Software/PulseAudio">PulseAudio</A>.  Note that RtAudio now only supports the newer version 4.0 OSS API.  The ALSA API is now part of the Linux kernel and offers significantly better functionality than the OSS API.  RtAudio provides support for the 1.0 and higher versions of ALSA.  Jack is a low-latency audio server written primarily for the GNU/Linux operating system. It can connect a number of different applications to an audio device, as well as allow them to share audio between themselves.  Input/output latency on the order of 15 milliseconds can typically be achieved using any of the Linux APIs by fine-tuning the RtAudio buffer parameters (without kernel modifications).  Latencies on the order of 5 milliseconds or less can be achieved using a low-latency kernel patch and increasing FIFO scheduling priority.  The pthread library, which is used for callback functionality, is a standard component of all Linux distributions.
+
+The ALSA library includes OSS emulation support.  That means that you can run programs compiled for the OSS API even when using the ALSA drivers and library.  It should be noted however that OSS emulation under ALSA is not perfect.  Specifically, channel number queries seem to consistently produce invalid results.  While OSS emulation is successful for the majority of RtAudio tests, it is recommended that the native ALSA implementation of RtAudio be used on systems which have ALSA drivers installed.
+
+The ALSA implementation of RtAudio makes no use of the ALSA "plug" interface.  All necessary data format conversions, channel compensation, de-interleaving, and byte-swapping is handled by internal RtAudio routines.
+
+\section macosx Macintosh OS-X (CoreAudio and Jack):
+
+The Apple CoreAudio API is designed to use a separate callback procedure for each of its audio devices.  A single RtAudio duplex stream using two different devices is supported, though it cannot be guaranteed to always behave correctly because we cannot synchronize these two callbacks.  The <I>numberOfBuffers</I> parameter to the RtAudio::openStream() function has no affect in this implementation.
+
+It is not possible to have multiple instances of RtAudio accessing the same CoreAudio device.
+
+The RtAudio Jack support can be compiled on Macintosh OS-X systems, as well as in Linux.
+
+\section windowsds Windows (DirectSound):
+
+The \c configure script provides support for the MinGW compiler.  DirectSound support is specified with the "--with-ds" flag.
+
+In order to compile RtAudio under Windows for the DirectSound API, you must have the header and source files for DirectSound version 5.0 or higher.  As far as I know, there is no DirectSoundCapture support for Windows NT.  Audio output latency with DirectSound can be reasonably good, especially since RtAudio version 3.0.2.  Input audio latency still tends to be bad but better since version 3.0.2.  RtAudio was originally developed with Visual C++ version 6.0 but has been tested with .NET.
+
+The DirectSound version of RtAudio can be compiled with or without the UNICODE preprocessor definition.
+
+\section windowsasio Windows (ASIO):
+
+ASIO support using MinGW and the \c configure script is specified with the "--with-asio" flag.
+
+The Steinberg ASIO audio API allows only a single device driver to be loaded and accessed at a time.  ASIO device drivers must be supplied by audio hardware manufacturers, though ASIO emulation is possible on top of systems with DirectSound drivers.  The <I>numberOfBuffers</I> parameter to the RtAudio::openStream() function has no affect in this implementation.
+
+A number of ASIO source and header files are required for use with RtAudio.  Specifically, an RtAudio project must include the following files: <TT>asio.h,cpp; asiodrivers.h,cpp; asiolist.h,cpp; asiodrvr.h; asiosys.h; ginclude.h; iasiodrv.h; iasiothiscallresolver.h,cpp</TT>.  The Visual C++ projects found in <TT>/tests/Windows/</TT> compile both ASIO and DirectSound support.
+
+The Steinberg provided <TT>asiolist</TT> class does not compile when the preprocessor definition UNICODE is defined.  Note that this could be an issue when using RtAudio with Qt, though Qt programs appear to compile without the UNICODE definition (try <tt>DEFINES -= UNICODE</tt> in your .pro file).  RtAudio with ASIO support has been tested using the MinGW compiler under Windows XP, as well as in the Visual Studio environment.

+\section debug Debugging
+
+If you are having problems getting RtAudio to run on your system, make sure to pass a value of \e true to the RtAudio::showWarnings() function (this is the default setting).  A variety of warning messages will be displayed which may help in determining the problem.  Also, try using the programs included in the <tt>tests</tt> directory.

+/*! \page errors Error Handling
+
+RtAudio makes restrained use of C++ exceptions.  That is, exceptions are thrown only when system errors occur that prevent further class operation or when the user makes invalid function calls.  In other cases, a warning message may be displayed and an appropriate value is returned.  For example, if a system error occurs when processing the RtAudio::getDeviceCount() function, the return value is zero.  In such a case, the user cannot expect to make use of most other RtAudio functions because no devices are available (and thus a stream cannot be opened).  A client can call the function RtAudio::showWarnings() with a boolean argument to enable or disable the printing of warning messages to <tt>stderr</tt>.  By default, warning messages are displayed.  There is a protected RtAudio method, error(), that can be modified to globally control how these messages are handled and reported.

+/*! \page multi Using Simultaneous Multiple APIs
+
+Because support for each audio API is encapsulated in a specific RtApi subclass, it is possible to compile and instantiate multiple API-specific subclasses on a given operating system.  For example, one can compile both the RtApiDs and RtApiAsio classes on Windows operating systems by providing the appropriate preprocessor definitions, include files, and libraries for each.  In a run-time situation, one might first attempt to determine whether any ASIO device drivers exist.  This can be done by specifying the api argument RtAudio::WINDOWS_ASIO when attempting to create an instance of RtAudio.  If no available devices are found, then an instance of RtAudio with the api argument RtAudio::WINDOWS_DS can be created.  Alternately, if no api argument is specified, RtAudio will first look for an ASIO instance and then a DirectSound instance (on Linux systems, the default API search order is Jack, Alsa, and finally OSS).  In theory, it should also be possible to have separate instances of RtAudio open at the same time with different underlying audio API support, though this has not been tested.  It is difficult to know how well different audio APIs can simultaneously coexist on a given operating system.  In particular, it is unlikely that the same device could be simultaneously controlled with two different audio APIs.
+
+The static function RtAudio::getCompiledApi() is provided to determine the available compiled API support.  The function RtAudio::getCurrentApi() indicates the API selected for a given RtAudio instance.

+
+We open the stream in exactly the same way as the previous example (except with a data format change) and specify the address of our callback function \e "saw()". The callback function will automatically be invoked when the underlying audio system needs data for output.  Note that the callback function is called only when the stream is "running" (between calls to the RtAudio::startStream() and RtAudio::stopStream() functions).  We can also pass a pointer value to the RtAudio::openStream() function that is made available in the callback function.  In this way, it is possible to gain access to arbitrary data created in our \e main() function from within the globally defined callback function.
+
+In this example, we stop the stream with an explicit call to RtAudio::stopStream().  It is also possible to stop a stream by returning a non-zero value from the callback function.  A return value of 1 will cause the stream to finish draining its internal buffers and then halt (equivalent to calling the RtAudio::stopStream() function).   A return value of 2 will cause the stream to stop immediately (equivalent to calling the RtAudio::abortStream() function).

+
+A programmer may wish to query the available audio device capabilities before deciding which to use.  The following example outlines how this can be done.

+
+#include <iostream>
+#include "RtAudio.h"

+      std::cout << "device = " << i;
+      std::cout << ": maximum output channels = " << info.outputChannels << "\n";
+    }
+  }
+
+  return 0;
+}
+\endcode
+
+The RtAudio::DeviceInfo structure is defined in RtAudio.h and provides a variety of information useful in assessing the capabilities of a device:
+
+\code
+  typedef struct RtAudio::DeviceInfo {
+    bool probed;                           // true if the device capabilities were successfully probed.
+    std::string name;                      // Character string device identifier.
+    unsigned int outputChannels;           // Maximum output channels supported by device.
+    unsigned int inputChannels;            // Maximum input channels supported by device.
+    unsigned int duplexChannels;           // Maximum simultaneous input/output channels supported by device.
+    bool isDefaultOutput;                  // true if this is the default output device.
+    bool isDefaultInput;                   // true if this is the default input device.
+    std::vector<unsigned int> sampleRates; // Supported sample rates.
+    RtAudioFormat nativeFormats;           // Bit mask of supported data formats.
+  };
+\endcode
+
+The following data formats are defined and fully supported by RtAudio:
+
+\code
+  typedef unsigned long RtAudioFormat;
+  static const RtAudioFormat  RTAUDIO_SINT8;   // Signed 8-bit integer
+  static const RtAudioFormat  RTAUDIO_SINT16;  // Signed 16-bit integer
+  static const RtAudioFormat  RTAUDIO_SINT24;  // Signed 24-bit integer (lower 3 bytes of 32-bit signed integer.)
+  static const RtAudioFormat  RTAUDIO_SINT32;  // Signed 32-bit integer
+  static const RtAudioFormat  RTAUDIO_FLOAT32; // 32-bit float normalized between +/- 1.0
+  static const RtAudioFormat  RTAUDIO_FLOAT64; // 64-bit double normalized between +/- 1.0
+\endcode
+
+The \c nativeFormats member of the RtAudio::DeviceInfo structure is a bit mask of the above formats which are natively supported by the device.  However, RtAudio will automatically provide format conversion if a particular format is not natively supported.  When the \c probed member of the RtAudio::DeviceInfo structure is false, the remaining structure members are undefined and the device is probably unusable.
+
+Some audio devices may require a minimum channel value greater than one.  RtAudio will provide automatic channel number compensation when the number of channels set by the user is less than that required by the device.  Channel compensation is <I>NOT</I> possible when the number of channels set by the user is greater than that supported by the device.
+
+It should be noted that the capabilities reported by a device driver or underlying audio API are not always accurate and/or may be dependent on a combination of device settings.  For this reason, RtAudio does not rely on the queried values when attempting to open a stream.

+
+The RtAudio::openStream() function attempts to open a stream with a specified set of parameter values.  In the above example, we attempt to open a two channel playback stream using the default output device, 32-bit floating point data, a sample rate of 44100 Hz, and a frame rate of 256 sample frames per output buffer.  If the user specifies an invalid parameter value (such as a device id greater than or equal to the number of enumerated devices), an RtError is thrown of type = INVALID_USE.   If a system error occurs or the device does not support the specified parameter values, an RtError of type = SYSTEM_ERROR is thrown.  In either case, a descriptive error message is bundled with the exception and can be queried with the RtError::getMessage() or RtError::what() functions.
+
+RtAudio provides four signed integer and two floating point data formats which can be specified using the RtAudioFormat parameter values mentioned earlier.  If the opened device does not natively support the given format, RtAudio will automatically perform the necessary data format conversion.
+
+The \c bufferFrames parameter specifies the desired number of sample frames that will be written to and/or read from a device per write/read operation.  This parameter can be used to control stream latency though there is no guarantee that the passed value will be that used by a device.  In general, a lower \c bufferFrames value will produce less latency but perhaps less robust performance.  A value of zero can be specified, in which case the smallest allowable value will be used.  The \c bufferFrames parameter is passed as a pointer and the actual value used by the stream is set during the device setup procedure.  \c bufferFrames values should be a power of two.  Optimal and allowable buffer values tend to vary between systems and devices.  Stream latency can also be controlled via the optional RtAudio::StreamOptions member \c numberOfBuffers (not used in the example above), though this tends to be more system dependent.  In particular, the \c numberOfBuffers parameter is ignored when using the OS-X Core Audio, Jack, and the Windows ASIO APIs.
+
+As noted earlier, the device capabilities reported by a driver or underlying audio API are not always accurate and/or may be dependent on a combination of device settings.  Because of this, RtAudio does not attempt to query a device's capabilities or use previously reported values when opening a device.  Instead, RtAudio simply attempts to set the given parameters on a specified device and then checks whether the setup is successful or not.
+
+The RtAudioCallback parameter above is a pointer to a user-defined function that will be called whenever the audio system is ready for new output data or has new input data to be read.  Further details on the use of a callback function are provided in the next section.
+
+Several stream options are available to fine-tune the behavior of an audio stream.  In the example above, we specify that data will be written by the user in a \e non-interleaved format via the RtAudio::StreamOptions member \c flags.  That is, all \c bufferFrames of the first channel should be written consecutively, followed by all \c bufferFrames of the second channel.  By default (when no option is specified), RtAudio expects data to be written in an \e interleaved format.

+/*! \mainpage The RtAudio Home Page
+
+RtAudio is a set of C++ classes that provide a common API (Application Programming Interface) for realtime audio input/output across Linux, Macintosh OS-X and Windows operating systems.  RtAudio significantly simplifies the process of interacting with computer audio hardware.  It was designed with the following objectives:
+
+<UL>
+  <LI>object-oriented C++ design</LI>
+  <LI>simple, common API across all supported platforms</LI>
+  <LI>only one source and two header files for easy inclusion in programming projects</LI>
+  <LI>allow simultaneous multi-api support</LI>
+  <LI>support dynamic connection of devices</LI>
+  <LI>provide extensive audio device parameter control</LI>
+  <LI>allow audio device capability probing</LI>
+  <LI>automatic internal conversion for data format, channel number compensation, (de)interleaving, and byte-swapping</LI>
+</UL>
+
+RtAudio incorporates the concept of audio streams, which represent audio output (playback) and/or input (recording).  Available audio devices and their capabilities can be enumerated and then specified when opening a stream.  Where applicable, multiple API support can be compiled and a particular API specified when creating an RtAudio instance.  See the \ref apinotes section for information specific to each of the supported audio APIs.
+
+\section whatsnew What's New (Version 4.0)
+
+RtAudio V4 represents a significant rewrite of the code and includes a number of API and functionality changes from previous versions. A partial list of the changes includes:
+- new support for non-interleaved user data
+- additional input/output parameter specifications, including channel offset
+- new support for dynamic connection of devices
+- new support for stream time
+- revised callback arguments, including separate input and output buffer arguments
+- revised C++ exception handling
+- updated support for OSS version 4.0
+- discontinued support of blocking functionality
+- discontinued support of SGI
+
+Devices are now re-enumerated every time the RtAudio::getDeviceCount(), RtAudio::getDeviceInfo(), and RtAudio::openStream() functions are called.  This allows for the proper identification of hot-pluggable (USB, Firewire, ...) devices that are connected after an RtAudio instance is created.

+<p>The following flags can be OR'ed together to allow a client to make changes to the default stream behavior:</p>
+<ul>
+<li><em>RTAUDIO_NONINTERLEAVED:</em> Use non-interleaved buffers (default = interleaved).</li>
+<li><em>RTAUDIO_MINIMIZE_LATENCY:</em> Attempt to set stream parameters for lowest possible latency.</li>
+<li><em>RTAUDIO_HOG_DEVICE:</em> Attempt grab device for exclusive use.</li>
+<li><em>RTAUDIO_ALSA_USE_DEFAULT:</em> Use the "default" PCM device (ALSA only).</li>
+</ul>
+<p>By default, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> streams pass and receive audio data from the client in an interleaved format. By passing the RTAUDIO_NONINTERLEAVED flag to the openStream() function, audio data will instead be presented in non-interleaved buffers. In this case, each buffer argument in the RtAudioCallback function will point to a single array of data, with <code>nFrames</code> samples for each channel concatenated back-to-back. For example, the first sample of data for the second channel would be located at index <code>nFrames</code> (assuming the <code>buffer</code> pointer was recast to the correct data type for the stream).</p>
+<p>Certain audio APIs offer a number of parameters that influence the I/O latency of a stream. By default, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will attempt to set these parameters internally for robust (glitch-free) performance (though some APIs, like Windows Direct Sound, make this difficult). By passing the RTAUDIO_MINIMIZE_LATENCY flag to the openStream() function, internal stream settings will be influenced in an attempt to minimize stream latency, though possibly at the expense of stream performance.</p>
+<p>If the RTAUDIO_HOG_DEVICE flag is set, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will attempt to open the input and/or output stream device(s) for exclusive use. Note that this is not possible with all supported audio APIs.</p>
+<p>If the RTAUDIO_SCHEDULE_REALTIME flag is set, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will attempt to select realtime scheduling (round-robin) for the callback thread.</p>
+<p>If the RTAUDIO_ALSA_USE_DEFAULT flag is set, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will attempt to open the "default" PCM device when using the ALSA API. Note that this will override any specified input or output device id. </p>

+<p>The <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> API incorporates many of the concepts developed in the <a href="http://www.portaudio.com/">PortAudio</a> project by Phil Burk and Ross Bencina. Early development also incorporated ideas from Bill Schottstaedt's <a href="http://www-ccrma.stanford.edu/software/snd/sndlib/">sndlib</a>. The CCRMA <a href="http://www-ccrma.stanford.edu/groups/soundwire/">SoundWire group</a> provided valuable feedback during the API proposal stages.</p>
+<p>The early 2.0 version of <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> was slowly developed over the course of many months while in residence at the <a href="http://www.iua.upf.es/">Institut Universitari de L'Audiovisual (IUA)</a> in Barcelona, Spain and the <a href="http://www.acoustics.hut.fi/">Laboratory of Acoustics and Audio Signal Processing</a> at the Helsinki University of Technology, Finland. Much subsequent development happened while working at the <a href="http://www-ccrma.stanford.edu/">Center for Computer Research in Music and Acoustics (CCRMA)</a> at <a href="http://www.stanford.edu/">Stanford University</a>. All recent versions of <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> have been completed while working as an assistant / associate professor of <a href="http://www.music.mcgill.ca/musictech/">Music Technology</a> at <a href="http://www.mcgill.ca/">McGill University</a>.

+<h1><a class="anchor" id="apinotes">API Notes </a></h1><p><a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> is designed to provide a common API across the various supported operating systems and audio libraries. Despite that, some issues should be mentioned with regard to each.</p>
+<h2><a class="anchor" id="linux">
+Linux:</a></h2>
+<p><a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> for Linux was developed under Redhat distributions 7.0 - Fedora. Four different audio APIs are supported on Linux platforms: <a href="http://www.opensound.com/oss.html">OSS</a> (versions &gt;= 4.0), <a href="http://www.alsa-project.org/">ALSA</a>, <a href="http://jackit.sourceforge.net/">Jack</a>, and <a href="http://www.freedesktop.org/wiki/Software/PulseAudio">PulseAudio</a>. Note that <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> now only supports the newer version 4.0 OSS API. The ALSA API is now part of the Linux kernel and offers significantly better functionality than the OSS API. <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> provides support for the 1.0 and higher versions of ALSA. Jack is a low-latency audio server written primarily for the GNU/Linux operating system. It can connect a number of different applications to an audio device, as well as allow them to share audio between themselves. Input/output latency on the order of 15 milliseconds can typically be achieved using any of the Linux APIs by fine-tuning the <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> buffer parameters (without kernel modifications). Latencies on the order of 5 milliseconds or less can be achieved using a low-latency kernel patch and increasing FIFO scheduling priority. The pthread library, which is used for callback functionality, is a standard component of all Linux distributions.</p>
+<p>The ALSA library includes OSS emulation support. That means that you can run programs compiled for the OSS API even when using the ALSA drivers and library. It should be noted however that OSS emulation under ALSA is not perfect. Specifically, channel number queries seem to consistently produce invalid results. While OSS emulation is successful for the majority of <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> tests, it is recommended that the native ALSA implementation of <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> be used on systems which have ALSA drivers installed.</p>
+<p>The ALSA implementation of <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> makes no use of the ALSA "plug" interface. All necessary data format conversions, channel compensation, de-interleaving, and byte-swapping is handled by internal <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> routines.</p>
+<h2><a class="anchor" id="macosx">
+Macintosh OS-X (CoreAudio and Jack):</a></h2>
+<p>The Apple CoreAudio API is designed to use a separate callback procedure for each of its audio devices. A single <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> duplex stream using two different devices is supported, though it cannot be guaranteed to always behave correctly because we cannot synchronize these two callbacks. The <em>numberOfBuffers</em> parameter to the <a class="el" href="classRtAudio.html#afacc99740fa4c5606fb35467cdea6da8" title="A public function for opening a stream with the specified parameters.">RtAudio::openStream()</a> function has no affect in this implementation.</p>
+<p>It is not possible to have multiple instances of <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> accessing the same CoreAudio device.</p>
+<p>The <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> Jack support can be compiled on Macintosh OS-X systems, as well as in Linux.</p>
+<h2><a class="anchor" id="windowsds">
+Windows (DirectSound):</a></h2>
+<p>The <code>configure</code> script provides support for the MinGW compiler. DirectSound support is specified with the "--with-ds" flag.</p>
+<p>In order to compile <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> under Windows for the DirectSound API, you must have the header and source files for DirectSound version 5.0 or higher. As far as I know, there is no DirectSoundCapture support for Windows NT. Audio output latency with DirectSound can be reasonably good, especially since <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> version 3.0.2. Input audio latency still tends to be bad but better since version 3.0.2. <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> was originally developed with Visual C++ version 6.0 but has been tested with .NET.</p>
+<p>The DirectSound version of <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> can be compiled with or without the UNICODE preprocessor definition.</p>
+<h2><a class="anchor" id="windowsasio">
+Windows (ASIO):</a></h2>
+<p>ASIO support using MinGW and the <code>configure</code> script is specified with the "--with-asio" flag.</p>
+<p>The Steinberg ASIO audio API allows only a single device driver to be loaded and accessed at a time. ASIO device drivers must be supplied by audio hardware manufacturers, though ASIO emulation is possible on top of systems with DirectSound drivers. The <em>numberOfBuffers</em> parameter to the <a class="el" href="classRtAudio.html#afacc99740fa4c5606fb35467cdea6da8" title="A public function for opening a stream with the specified parameters.">RtAudio::openStream()</a> function has no affect in this implementation.</p>
+<p>A number of ASIO source and header files are required for use with <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a>. Specifically, an <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> project must include the following files: <code>asio.h,cpp; asiodrivers.h,cpp; asiolist.h,cpp; asiodrvr.h; asiosys.h; ginclude.h; iasiodrv.h; iasiothiscallresolver.h,cpp</code>. The Visual C++ projects found in <code>/tests/Windows/</code> compile both ASIO and DirectSound support.</p>
+<p>The Steinberg provided <code>asiolist</code> class does not compile when the preprocessor definition UNICODE is defined. Note that this could be an issue when using <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> with Qt, though Qt programs appear to compile without the UNICODE definition (try <code>DEFINES -= UNICODE</code> in your .pro file). <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> with ASIO support has been tested using the MinGW compiler under Windows XP, as well as in the Visual Studio environment. </p>

+<h1><a class="anchor" id="errors">Error Handling </a></h1><p><a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> makes restrained use of C++ exceptions. That is, exceptions are thrown only when system errors occur that prevent further class operation or when the user makes invalid function calls. In other cases, a warning message may be displayed and an appropriate value is returned. For example, if a system error occurs when processing the <a class="el" href="classRtAudio.html#a747ce2d73803641bbb66d6e78092aa1a" title="A public function that queries for the number of audio devices available.">RtAudio::getDeviceCount()</a> function, the return value is zero. In such a case, the user cannot expect to make use of most other <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> functions because no devices are available (and thus a stream cannot be opened). A client can call the function <a class="el" href="classRtAudio.html#af0752ee51cce3dd90a3bd009f9fdbe77" title="Specify whether warning messages should be printed to stderr.">RtAudio::showWarnings()</a> with a boolean argument to enable or disable the printing of warning messages to <code>stderr</code>. By default, warning messages are displayed. There is a protected <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> method, error(), that can be modified to globally control how these messages are handled and reported. </p>

+<h1>The <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> Home Page </h1><h3 class="version">4.0.11 </h3><p><a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> is a set of C++ classes that provide a common API (Application Programming Interface) for realtime audio input/output across Linux, Macintosh OS-X and Windows operating systems. <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> significantly simplifies the process of interacting with computer audio hardware. It was designed with the following objectives:</p>
+<ul>
+<li>
+object-oriented C++ design </li>
+<li>
+simple, common API across all supported platforms </li>
+<li>
+only one source and two header files for easy inclusion in programming projects </li>
+<li>
+allow simultaneous multi-api support </li>
+<li>
+support dynamic connection of devices </li>
+<li>
+provide extensive audio device parameter control </li>
+<li>
+allow audio device capability probing </li>
+<li>
+automatic internal conversion for data format, channel number compensation, (de)interleaving, and byte-swapping </li>
+</ul>
+<p><a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> incorporates the concept of audio streams, which represent audio output (playback) and/or input (recording). Available audio devices and their capabilities can be enumerated and then specified when opening a stream. Where applicable, multiple API support can be compiled and a particular API specified when creating an <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> instance. See the <a class="el" href="apinotes.html">API Notes</a> section for information specific to each of the supported audio APIs.</p>
+<h2><a class="anchor" id="whatsnew">
+What's New (Version 4.0)</a></h2>
+<p><a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> V4 represents a significant rewrite of the code and includes a number of API and functionality changes from previous versions. A partial list of the changes includes:</p>
+<ul>
+<li>new support for non-interleaved user data</li>
+<li>additional input/output parameter specifications, including channel offset</li>
+<li>new support for dynamic connection of devices</li>
+<li>new support for stream time</li>
+<li>revised callback arguments, including separate input and output buffer arguments</li>
+<li>revised C++ exception handling</li>
+<li>updated support for OSS version 4.0</li>
+<li>discontinued support of blocking functionality</li>
+<li>discontinued support of SGI</li>
+</ul>
+<p>Devices are now re-enumerated every time the <a class="el" href="classRtAudio.html#a747ce2d73803641bbb66d6e78092aa1a" title="A public function that queries for the number of audio devices available.">RtAudio::getDeviceCount()</a>, <a class="el" href="classRtAudio.html#a02d7ff44ad1d7eae22283a052f3dfda8" title="Return an RtAudio::DeviceInfo structure for a specified device number.">RtAudio::getDeviceInfo()</a>, and <a class="el" href="classRtAudio.html#afacc99740fa4c5606fb35467cdea6da8" title="A public function for opening a stream with the specified parameters.">RtAudio::openStream()</a> functions are called.

+<h1><a class="anchor" id="multi">Using Simultaneous Multiple APIs </a></h1><p>Because support for each audio API is encapsulated in a specific RtApi subclass, it is possible to compile and instantiate multiple API-specific subclasses on a given operating system. For example, one can compile both the RtApiDs and RtApiAsio classes on Windows operating systems by providing the appropriate preprocessor definitions, include files, and libraries for each. In a run-time situation, one might first attempt to determine whether any ASIO device drivers exist. This can be done by specifying the api argument <a class="el" href="classRtAudio.html#ac9b6f625da88249d08a8409a9db0d849a219517d1df90f94d07758481155bd469">RtAudio::WINDOWS_ASIO</a> when attempting to create an instance of <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a>. If no available devices are found, then an instance of <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> with the api argument <a class="el" href="classRtAudio.html#ac9b6f625da88249d08a8409a9db0d849a28478830f42c2fd61e6c7ad498901931">RtAudio::WINDOWS_DS</a> can be created. Alternately, if no api argument is specified, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will first look for an ASIO instance and then a DirectSound instance (on Linux systems, the default API search order is Jack, Alsa, and finally OSS). In theory, it should also be possible to have separate instances of <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> open at the same time with different underlying audio API support, though this has not been tested. It is difficult to know how well different audio APIs can simultaneously coexist on a given operating system. In particular, it is unlikely that the same device could be simultaneously controlled with two different audio APIs.</p>

In the above example, we attempt to open a two channel playback stream using the default output device, 32-bit floating point data, a sample rate of 44100 Hz, and a frame rate of 256 sample frames per output buffer. If the user specifies an invalid parameter value (such as a device id greater than or equal to the number of enumerated devices), an <a class="el" href="classRtError.html" title="Exception handling class for RtAudio &amp; RtMidi.">RtError</a> is thrown of type = INVALID_USE. If a system error occurs or the device does not support the specified parameter values, an <a class="el" href="classRtError.html" title="Exception handling class for RtAudio &amp; RtMidi.">RtError</a> of type = SYSTEM_ERROR is thrown. In either case, a descriptive error message is bundled with the exception and can be queried with the <a class="el" href="classRtError.html#afd067ba6b46edd37f989cad02cd70b50" title="Returns the thrown error message string.">RtError::getMessage()</a> or <a class="el" href="classRtError.html#aeb843b7a7785d66061c61ebfc29e7e9d" title="Returns the thrown error message as a c-style string.">RtError::what()</a> functions.</p>
+<p><a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> provides four signed integer and two floating point data formats which can be specified using the RtAudioFormat parameter values mentioned earlier. If the opened device does not natively support the given format, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will automatically perform the necessary data format conversion.</p>
+<p>The <code>bufferFrames</code> parameter specifies the desired number of sample frames that will be written to and/or read from a device per write/read operation. This parameter can be used to control stream latency though there is no guarantee that the passed value will be that used by a device. In general, a lower <code>bufferFrames</code> value will produce less latency but perhaps less robust performance. A value of zero can be specified, in which case the smallest allowable value will be used. The <code>bufferFrames</code> parameter is passed as a pointer and the actual value used by the stream is set during the device setup procedure. <code>bufferFrames</code> values should be a power of two. Optimal and allowable buffer values tend to vary between systems and devices. Stream latency can also be controlled via the optional <a class="el" href="structRtAudio_1_1StreamOptions.html" title="The structure for specifying stream options.">RtAudio::StreamOptions</a> member <code>numberOfBuffers</code> (not used in the example above), though this tends to be more system dependent. In particular, the <code>numberOfBuffers</code> parameter is ignored when using the OS-X Core Audio, Jack, and the Windows ASIO APIs.</p>
+<p>As noted earlier, the device capabilities reported by a driver or underlying audio API are not always accurate and/or may be dependent on a combination of device settings. Because of this, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> does not attempt to query a device's capabilities or use previously reported values when opening a device. Instead, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> simply attempts to set the given parameters on a specified device and then checks whether the setup is successful or not.</p>
+<p>The RtAudioCallback parameter above is a pointer to a user-defined function that will be called whenever the audio system is ready for new output data or has new input data to be read. Further details on the use of a callback function are provided in the next section.</p>
+<p>Several stream options are available to fine-tune the behavior of an audio stream. In the example above, we specify that data will be written by the user in a <em>non-interleaved</em> format via the <a class="el" href="structRtAudio_1_1StreamOptions.html" title="The structure for specifying stream options.">RtAudio::StreamOptions</a> member <code>flags</code>. That is, all <code>bufferFrames</code> of the first channel should be written consecutively, followed by all <code>bufferFrames</code> of the second channel. By default (when no option is specified), <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> expects data to be written in an <em>interleaved</em> format. </p>

+<hr/><a name="_details"></a><h2>Detailed Description</h2>
+<p>The structure for specifying stream options. </p>
+<p>The following flags can be OR'ed together to allow a client to make changes to the default stream behavior:</p>
+<ul>
+<li><em>RTAUDIO_NONINTERLEAVED:</em> Use non-interleaved buffers (default = interleaved).</li>
+<li><em>RTAUDIO_MINIMIZE_LATENCY:</em> Attempt to set stream parameters for lowest possible latency.</li>
+<li><em>RTAUDIO_HOG_DEVICE:</em> Attempt grab device for exclusive use.</li>
+<li><em>RTAUDIO_SCHEDULE_REALTIME:</em> Attempt to select realtime scheduling for callback thread.</li>
+<li><em>RTAUDIO_ALSA_USE_DEFAULT:</em> Use the "default" PCM device (ALSA only).</li>
+</ul>
+<p>By default, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> streams pass and receive audio data from the client in an interleaved format. By passing the RTAUDIO_NONINTERLEAVED flag to the <a class="el" href="classRtAudio.html#afacc99740fa4c5606fb35467cdea6da8" title="A public function for opening a stream with the specified parameters.">openStream()</a> function, audio data will instead be presented in non-interleaved buffers. In this case, each buffer argument in the RtAudioCallback function will point to a single array of data, with <code>nFrames</code> samples for each channel concatenated back-to-back. For example, the first sample of data for the second channel would be located at index <code>nFrames</code> (assuming the <code>buffer</code> pointer was recast to the correct data type for the stream).</p>
+<p>Certain audio APIs offer a number of parameters that influence the I/O latency of a stream. By default, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will attempt to set these parameters internally for robust (glitch-free) performance (though some APIs, like Windows Direct Sound, make this difficult). By passing the RTAUDIO_MINIMIZE_LATENCY flag to the <a class="el" href="classRtAudio.html#afacc99740fa4c5606fb35467cdea6da8" title="A public function for opening a stream with the specified parameters.">openStream()</a> function, internal stream settings will be influenced in an attempt to minimize stream latency, though possibly at the expense of stream performance.</p>
+<p>If the RTAUDIO_HOG_DEVICE flag is set, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will attempt to open the input and/or output stream device(s) for exclusive use. Note that this is not possible with all supported audio APIs.</p>
+<p>If the RTAUDIO_SCHEDULE_REALTIME flag is set, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will attempt to select realtime scheduling (round-robin) for the callback thread. The <code>priority</code> parameter will only be used if the RTAUDIO_SCHEDULE_REALTIME flag is set. It defines the thread's realtime priority.</p>
+<p>If the RTAUDIO_ALSA_USE_DEFAULT flag is set, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will attempt to open the "default" PCM device when using the ALSA API. Note that this will override any specified input or output device id.</p>
+<p>The <code>numberOfBuffers</code> parameter can be used to control stream latency in the Windows DirectSound, Linux OSS, and Linux Alsa APIs only. A value of two is usually the smallest allowed. Larger numbers can potentially result in more robust stream performance, though likely at the cost of stream latency. The value set by the user is replaced during execution of the <a class="el" href="classRtAudio.html#afacc99740fa4c5606fb35467cdea6da8" title="A public function for opening a stream with the specified parameters.">RtAudio::openStream()</a> function by the value actually used by the system.</p>
+<p>The <code>streamName</code> parameter can be used to set the client name when using the Jack API. By default, the client name is set to RtApiJack. However, if you wish to create multiple instances of <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> with Jack, each instance must have a unique client name. </p>

+<h2>Details:</h2>
+
+<a name="1"><sup>1</sup></a>Currently implemented by incrementing a counter every time the tickStream() or callback function is called.  If the gettimeofday() function is available (right now it is enabled for all Unix-like systems but not Windows), it also records the time of each tickStream() call.  Then, when you call getStreamTime(), it adds the elapsed time since the last tickStream also.  This makes the playback counter pretty smooth, but accurate.  The intent is that now we could implement something more accurate on platforms that support it - but this is a reasonable baseline.  One thing to watch out for: asking OSS for the stream time is problematic; on some devices the counter is only 16-bit and wraps around frequently, and on some devices it will sometimes return bogus values.
+<P>
+<P>
+<a name="2"><sup>2</sup></a>This function could not be implemented for all APIs.  If the function returns a value of zero, it should be assumed to be invalid.
+<P>
+<P>
+<a name="3"><sup>3</sup></a>This implementation does not attempt to leave a device as-is.  However, the flag <tt>RTAUDIO_HOG_DEVICE</tt> is provided to attempt to grab exclusive use of a device.
+<P>
+<P>
+<a name="4"><sup>4</sup></a>I actually coded this up for OS-X Core Audio.  However, I found it bloated the code and presented a number of interface problems that did more harm than good.  Thus, it is currently not being considered further (GS).
