| 33 | <application>PulseAudio</application> is a sound system for POSIX OSes,
|
|---|
| 34 | meaning that it is a proxy for sound applications. It allows you to do
|
|---|
| 35 | advanced operations on your sound data as it passes between your application
|
|---|
| 36 | and your hardware. Things like transferring the audio to a different machine,
|
|---|
| 37 | changing the sample format or channel count and mixing several sounds into
|
|---|
| 38 | one are easily achieved using a sound server.
