<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>
