Defining Timeline Audio Track Channels at Creation
If you decide to create a new audio track, you have to choose what kind of audio track it will be.
Right-clicking in the bottom audio portion of the Timeline track header reveals a contextual
sub-menu that lets you create different kinds of audio tracks.
 Mono: Holds a single channel with only one lane.
 Stereo: Holds stereo left and right channels, with two lanes.
 5.1: Holds the six channels corresponding to a 5.1 surround mix, for a total of six lanes.
For broadcast, SMPTE specifies Left, Center, Right, Left Surround, Right Surround, and
LFE. For cinema distribution these tracks are ordered Left, Right, Center, LFE, Surround
Left, and Surround Right.
 7.1: Holds the eight channels corresponding to a 7.1 surround mix, for a total of eight
lanes. For broadcast, SMPTE specifies Left, Center, Right, Left Surround, Right
Surround, LFE, Back Surround Left, and Back Surround Right. For cinema distribution
these tracks are ordered Left, Right, Center, LFE, Left Surround, Right Surround, Back
Left Surround, and Back Right Surround.
 Adaptive: Capable of holding up to 24 audio channels, which would display up
to 24 lanes within the track. An adaptive audio track can hold clips with different
combinations of channels, up to the maximum number of channels allowed within
that track. The number of channels allowable on a particular Adaptive track is user-
definable (1–24) at the time that track is created. If you edit a clip with more channels
into an Adaptive track that was created to hold fewer channels, the extra clip channels
are muted.
Creating Tracks
There are two commands with which to create new audio tracks, and both are in the contextual
menu found by right-clicking within any audio track’s header controls. Add Track adds a single
audio track of the type you choose from a submenu. Add Tracks lets you insert as many tracks
as you like, of a type and at a position you designate using the Add Tracks dialog.
Rearranging Tracks
You can rearrange tracks by right-clicking in a track’s header area and choosing either Move
Track Up or Move Track Down in the contextual menu that appears.
Changing How Many Channels an Audio Track Has
If you had set up your timeline with one kind of audio track, but you discover you actually need
a different kind, you can change any audio track’s type at any time. Just right-click anywhere in
that audio track’s timeline header, and choose an option from the Change Track Type To
submenu of the contextual menu.
Deleting Tracks
Right-click within a track’s Timeline header and choose Delete Track. If there are clips on a
track you remove, they are also deleted from the Timeline, but preserved in the Media Pool.
