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. |
