Copy the audio tracks n, m etc. The numbers are track IDs which can be obtained with the --identify switch. They're not simply the track numbers (see section track IDs). Default: copy all audio tracks.
Instead of track IDs you can also provide ISO 639-2 language codes. This will only work for source files that provide language tags for their tracks.
Default: copy all tracks of this kind.
If the IDs are prefixed with ! then the meaning is reversed: copy all tracks of this kind but the ones listed after the !.
