Detailed Description

Audio track, the collection of audio clips.

An audio track is an entity that holds audio clips. Multiple audio clips can be added or removed from audio track. At the joint of two audio clips, an audio transition could be inserted.

Note: For the meaning of a series of interfaces and parameters of the audio track, please refer to the corresponding interface of the video track NvsVideoTrack.
