RtAudio is a set of C++ classes that provide a common API for realtime audio
input/output across different operating systems. RtAudio significantly
simplifies the process of interacting with computer audio hardware. It was
designed with the following objectives:

* object-oriented C++ design
* simple, common API across all supported platforms
* 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
