<a name="gst-plugins-base-libs-gstmixertrack.description"></a><h2>Description</h2>
<p>
Basic mixer control object (note that it is a GObject and not a GstObject).
</p>
<p>
A mixer track represents a single slider control of none, one or more
channels. A mixer track with no channels is usually interpreted as a
on/off switch control.
</p>
<p>
Note the presence of both min_volume and max_volume fields. Applications
must not assume that min_volume is 0 or max_volume is any particular
value.
