/**
* SECTION: gesaudiotrack
* @title: GESAudioTrack
* @short_description: A standard GESTrack for raw audio
* @short_description: A standard #GESTrack for raw audio
*
* Sane default properties to specify and fixate the output stream are
* set as restriction-caps.
* It is advised, to modify these properties, to use
* #ges_track_update_restriction_caps, setting them directly is
* possible through #ges_track_set_restriction_caps, but not specifying
* one of them can lead to negotiation issues, only use that function
* if you actually know what you're doing :)
* A #GESAudioTrack is a default audio #GESTrack, with a
* #GES_TRACK_TYPE_AUDIO #GESTrack:track-type and "audio/x-raw(ANY)"
* #GESTrack:caps.
*
* The default properties are:
* - format: S32LE
* By default, an audio track will have its #GESTrack:restriction-caps
* set to "audio/x-raw" with the following properties:
*
* - format: "S32LE"
* - channels: 2
* - rate: 44100
* - layout: interleaved
* - layout: "interleaved"
*
* These fields are needed for negotiation purposes, but you can change
* their values if you wish. It is advised that you do so using
* ges_track_update_restriction_caps() with new values for the fields you
* wish to change, and any additional fields you may want to add. Unlike
* using ges_track_set_restriction_caps(), this will ensure that these
* default fields will at least have some value set.
