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 …

RTAUDIO_SCHEDULE_REALTIME: Attempt to select realtime scheduling for callback thread. RTAUDIO_ALSA_USE_DEFAULT: Use the "default" PCM device (ALSA only). By default, …

In this example, we provide a complete program that demonstrates the use of RtAudio for audio playback. Our program produces a two-channel sawtooth waveform for output.

RtAudio is designed to provide a common API across the various supported operating systems and audio libraries. Despite that, some issues should be mentioned with regard to each. Linux: …

RtAudio provides four signed integer and two floating point data formats that can be specified using the RtAudioFormat parameter values mentioned earlier. If the opened device does not …

If the RTAUDIO_SCHEDULE_REALTIME flag is set, RtAudio will attempt to select realtime scheduling (round-robin) for the callback thread. If the RTAUDIO_ALSA_USE_DEFAULT flag …

RtAudio offers a C-style interface, principally for use in binding RtAudio to other programming languages. All structs, enums, and functions listed here have direct analogs (and simply call …

Using RtAudio for audio input is almost identical to the way it is used for playback. Here's the blocking playback example rewritten for recording:

In a run-time situation, one might first attempt to determine whether any ASIO device drivers exist. This can be done by specifying the api argument RtAudio::WINDOWS_ASIO when attempting …

If you are having problems getting RtAudio to run on your system, make sure to pass a value of true to the RtAudio::showWarnings() function (this is the default setting). A variety of warning …
