# RtAudio

[](https://travis-ci.org/thestk/rtaudio)
|
||||
|
||||
|
||||
A set of C++ classes that provide a common API for realtime audio input/output across Linux (native ALSA, JACK, PulseAudio and OSS), Macintosh OS X (CoreAudio and JACK), and Windows (DirectSound, ASIO and WASAPI) operating systems.

|
||||
|
||||
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.
|
||||
|
||||
## Building
|
||||
|
||||
Several build systems are available. These are:
|
||||
|
||||
- autotools (`./autogen.sh; make` from git, or `./configure; make` from tarball release)
|
||||
- CMake (`mkdir build; cd build; ../cmake; make`)
|
||||
- meson (`meson build; cd build; ninja`)
|
||||
|
||||
See `install.txt` for more instructions about how to select the audio backend API. By
|
||||
default all detected APIs will be enabled.
|
||||
|
||||
We recommend using the autotools-based build for packaging purposes. Please note that
|
||||
RtAudio is designed as a single `.cpp` and `.h` file so that it is easy to copy directly
|
||||
into a project. In that case you need to define the appropriate flags for the desired
|
||||
backend APIs.
|
||||
|
||||
## FAQ
|
||||
|
||||
### Why does audio only come to one ear when I choose 1-channel output?
|
||||
|
||||
RtAudio doesn't automatically turn 1-channel output into stereo output with copied values
|
||||
to each channel, it really only opens one channel. So, if this is the behaviour you want,
|
||||
you have to do this copying in your audio stream callback.
|
||||

||||
