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 one header file 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>
+- object-oriented C++ design
+- simple, common API across all supported platforms
+- only one source and one header file for easy inclusion in programming projects
+- allow simultaneous multi-api support
+- support dynamic connection of devices
+- provide extensive audio device parameter control
+- allow audio device capability probing
+- automatic internal conversion for data format, channel number compensation, (de)interleaving, and byte-swapping
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.
