16## Overview
17
18RtAudio is a set of C++ classes that provides a common API (Application Programming Interface) for realtime audio input/output across Linux (native ALSA, JACK, PulseAudio and OSS), Macintosh OS X and Windows (DirectSound, ASIO and WASAPI) operating systems.  RtAudio significantly simplifies the process of interacting with computer audio hardware.  It was designed with the following objectives:
19
20  - object-oriented C++ design
21  - simple, common API across all supported platforms
22  - only one source and one header file for easy inclusion in programming projects
23  - allow simultaneous multi-api support
24  - support dynamic connection of devices
25  - provide extensive audio device parameter control
26  - allow audio device capability probing
27  - automatic internal conversion for data format, channel number compensation, (de)interleaving, and byte-swapping
28
29RtAudio 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.
