tracks

Identify a track from the input audio to include in this selector by entering the track index number. These numberings include only tracks recognized as audio. If the service recognizes more types of audio tracks in the future, these numberings may shift. To include several tracks in a single audio selector, specify multiple tracks as follows. Using the console, enter a comma-separated list. For example, type "1,2,3" to include tracks 1 through 3.
