<title>PulseAudio</title>
<p>
PulseAudio is GNOME's low-level audio API. It is what sits between
applications and the kernel's audio API. PulseAudio lets you re-route
sound through the network, or to a Bluetooth headset. It can mix several
sources of audio, or change the sample rate of an audio stream.
</p>
<p>All the parts of GNOME that produce audio use PulseAudio in one way or
another, either directly, or indirectly through higher-level sound
manipulation APIs like <link xref="tech-gstreamer">GStreamer</link>.</p>
