+RtAudio - a C++ class which provides a common API for realtime audio input/output across Linux (native ALSA and OSS), SGI, Macintosh OS X (CoreAudio), and Windows (DirectSound and ASIO) operating systems.
+
+By Gary P. Scavone, 2002.
+
+To configure and compile (on Unix systems):
+
+1. Unpack the RtAudio distribution (tar -xzf rtaudio-2.x.tar.gz).
+2. From within the directory containing this file, run configure:
+
+   ./configure
+
+3. From within the "tests" directory, type "make".
+
+A few options can be passed to configure, including:
+
+  --enable-debug = enable various debug output
+  --with-alsa = choose native ALSA API support (linux only)
+
+Typing "./configure --help" will display all the available options.
+
+If you wish to use a different compiler than that selected by configure, specify that compiler in the command line (ex. to use CC):
+
+  ./configure CXX=CC
+
+
+For Windows Users:
+
+Visual C++ 6.0 project files are included for the test programs.  For projects using the DirectSound API, go to the /tests/DirectSound/ directory.  For projects using the ASIO API, go to the /tests/asio/ directory.

-tests:    example RtAudio programs
-
-
-OVERVIEW:
-
-RtAudio is a C++ class which provides a common API (Application Programming Interface) for realtime audio input/output across Linux (native ALSA and OSS), SGI, and Windows operating systems. RtAudio significantly simplifies the process of interacting with computer audio hardware. It was designed with the following goals:
-
-  - object oriented C++ design
-  - simple, common API across all supported platforms
-  - single independent header and source file for easy inclusion in programming projects (no libraries!)
-  - blocking functionality
-  - callback functionality
-  - extensive audio device parameter control
-  - audio device capability probing
-  - automatic internal conversion for data format, channel number compensation, de-interleaving, and byte-swapping
-  - control over multiple audio streams and devices with a single instance
-
-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. Multiple streams can run at the same time and, when allowed by the underlying audio API, a single device can serve multiple streams.
-
-The RtAudio API provides both blocking (synchronous) and callback (asyncronous) functionality. Callbacks are typically used in conjunction with graphical user interfaces (GUI). Blocking functionality is often necessary for explicit control of multiple input/output stream synchronization or when audio must be synchronized with other system events. 
-
-
-LEGAL AND ETHICAL:
-
-This software was designed and created to be made publicly available for free, primarily for academic purposes, so if you use it, pass it on with this documentation, and for free.  
-
-If you make a million dollars with it, give me some.  If you make compositions with it, put me in the program notes.

+/*! \class RtError
+    \brief Exception handling class for RtAudio.
+
+    The RtError class is quite simple but it does allow errors to be
+    "caught" by RtError::TYPE. Almost all RtAudio methods can "throw"
+    an RtError, most typically if an invalid stream identifier is
+    supplied to a method or a driver error occurs. There are a number
+    of cases within RtAudio where warning messages may be displayed
+    but an exception is not thrown. There is a private RtAudio method,
+    error(), which can be modified to globally control how these
+    messages are handled and reported.

+By Gary P. Scavone, 2002.
+
+v2.1: (7 October 2002)
+- added Mac OS X CoreAudio support
+- added Windows ASIO support
+- API change to getDeviceInfo(): device argument must be an integer between 1 - getDeviceCount().
+- "configure" support added for unix systems
+- adopted MIT-like license
+- various internal structural changes and bug fixes
+
+v2.01: (27 April 2002)
+- Windows destructor bug fix when no devices available
+- RtAudioError class renamed to RtError
+- Preprocessor definitions changed slightly (i.e. __LINUX_OSS_ to __LINUX_OSS__) to conform with new Synthesis ToolKit distribution
+
+v2.0: (22 January 2002)
+- first release of new independent class
+

+
+using time info:
+it is recommended to use the new method with time info even if the asio
+device does not support timecode; continuous calls to ASIOGetSamplePosition
+and ASIOGetSampleRate are avoided, and there is a more defined relationship
+between callback time and the time info.
+
+see the example below.
+to initiate time info mode, after you have received the callbacks pointer in
+ASIOCreateBuffers, you will call the asioMessage callback with kAsioSupportsTimeInfo
+as the argument. if this returns 1, host has accepted time info mode.
+now host expects the new callback bufferSwitchTimeInfo to be used instead
+of the old bufferSwitch method. the ASIOTime structure is assumed to be valid
+and accessible until the callback returns.
+
+using time code:
+if the device supports reading time code, it will call host's asioMessage callback
+with kAsioSupportsTimeCode as the selector. it may then fill the according
+fields and set the kTcValid flag.
+host will call the future method with the kAsioEnableTimeCodeRead selector when
+it wants to enable or disable tc reading by the device. you should also support
+the kAsioCanTimeInfo and kAsioCanTimeCode selectors in ASIOFuture (see example).
+
+note:
+the AsioTimeInfo/ASIOTimeCode pair is supposed to work in both directions.
+as a matter of convention, the relationship between the sample
+position counter and the time code at buffer switch time is
+(ignoring offset between tc and sample pos when tc is running):
+
+on input:	sample 0 -> input  buffer sample 0 -> time code 0
+on output:	sample 0 -> output buffer sample 0 -> time code 0
+
+this means that for 'real' calculations, one has to take into account
+the according latencies.
+
+example:
+
+ASIOTime asioTime;
+
+in createBuffers()
+{
+	memset(&asioTime, 0, sizeof(ASIOTime));
+	AsioTimeInfo* ti = &asioTime.timeInfo;

+#if kCanTimeCode
+		if(callbacks->asioMessage(kAsioSupportsTimeCode, 0, 0, 0) == 1)
+			canTimeCode = true;
+#endif

+}

+		ti->samplePosition = theSamplePosition;

+	  (this is theoretical, meaning it does not include the overhead

+	  when bufferSitch() enters).
+	  This will usually be the size of one block in sample frames, plus
+	  device specific latencies.
+
+	  outputLatency will specify the time between the buffer switch,

+	  The next play buffer is defined as the one the host starts
+	  processing after (or at) bufferSwitch(), indicated by the
+	  index parameter (0 for buffer A, 1 for buffer B).
+	  It will usually be either one block, if the host writes directly
+	  to a dma buffer, or two or more blocks if the buffer is 'latched' by
+	  the driver. As an example, on ASIOStart(), the host will have filled
+	  the play buffer at index 1 already; when it gets the callback (with
+	  the parameter index == 0), this tells it to read from the input
+	  buffer 0, and start to fill the play buffer 0 (assuming that now
+	  play buffer 1 is already sounding). In this case, the output
+	  latency is one block. If the driver decides to copy buffer 1

+	  is most commonly done, but should be avoided), the output latency
+	  becomes two blocks instead, resulting in a total i/o latency of at least
+	  3 blocks. As memory access is the main bottleneck in native dsp processing,
+	  and to acheive less latency, it is highly recommended to try to avoid
+	  copying (this is also why the driver is the owner of the buffers). To
+	  summarize, the minimum i/o latency can be acheived if the input buffer
+	  is processed by the host into the output buffer which will physically
+	  start to sound on the next time slice. Also note that the host expects
+	  the bufferSwitch() callback to be accessed for each time slice in order
+	  to retain sync, possibly recursively; if it fails to process a block in

+		  are always independant form a channel index, that is, a channel
+		  index always counts from 0 to numInputs/numOutputs regardless
+		  of the group it may belong to.
+		  There will always be at least one group (group 0). Please
+		  also note that by default, the host may decide to activate
+		  channels 0 and 1; thus, these should belong to the most
+		  useful type (analog i/o, if present).
+	  	- type: on return, contains the sample type of the channel
+	  	- isActive: on return, ASIOTrue if channel is active as it was
+	  	  installed by ASIOCreateBuffers(), ASIOFalse else
+	  	- name:  describing the type of channel in question. Used to allow
+	  	  for user selection, and enabling of specific channels. examples:
+	      "Analog In", "SPDIF Out" etc
+	Returns:
+	  If no input/output is present ASE_NotPresent will be returned.
+	Notes:
+	  If possible, the string should be organised such that the first
+	  characters are most significantly describing the nature of the
+	  port, to allow for identification even if the view showing the
+	  port name is too small to display more than 8 characters, for

+/* Purpose:
+	  this tells the driver that the host has completed processing
+	  the output buffers. if the data format required by the hardware
+	  differs from the supported asio formats, but the hardware
+	  buffers are DMA buffers, the driver will have to convert
+	  the audio stream data; as the bufferSwitch callback is
+	  usually issued at dma block switch time, the driver will
+	  have to convert the *previous* host buffer, which increases
+	  the output latency by one block.
+	  when the host finds out that ASIOOutputReady() returns
+	  true, it will issue this call whenever it completed
+	  output processing. then the driver can convert the
+	  host data directly to the dma buffer to be played next,
+	  reducing output latency by one block.
+	  another way to look at it is, that the buffer switch is called
+	  in order to pass the *input* stream to the host, so that it can
+	  process the input into the output, and the output stream is passed
+	  to the driver when the host has completed its process.
+	Parameter:
+		None
+	Returns:
+	  only if the above mentioned scenario is given, and a reduction
+	  of output latency can be acheived by this mechanism, should
+	  ASE_OK be returned. otherwise (and usually), ASE_NotPresent
+	  should be returned in order to prevent further calls to this
+	  function. note that the host may want to determine if it is
+	  to use this when the system is not yet fully initialized, so
+	  ASE_OK should always be returned if the mechanism makes sense.	  
+	Notes:
+	  please remeber to adjust ASIOGetLatencies() according to
+	  whether ASIOOutputReady() was ever called or not, if your
+	  driver supports this scenario.
+	  also note that the engine may fail to call ASIO_OutputReady()
+	  in time in overload cases. as already mentioned, bufferSwitch
+      should be called for every block regardless of whether a block
+      could be processed in time.
