information on editing audio clips, see “
Editing Audio Clips in the Timeline
The name of an audio clip appears on the clip in the Timeline. By default, the entire
name appears on the clip if the clip is long enough to display it. You can change the
default behavior in the General pane of the Preferences window, so that long clip
names are truncated from the center. For information on setting preferences, see

Tracks, Busses, and Outputs
Multitrack projects contain tracks, busses, and outputs. Tracks, busses, and outputs
appear as horizontal rows in the Timeline and as vertical channel strips in the Mixer. In
both the Timeline and Mixer, tracks, busses, and outputs are grouped together, with a
separator between each category. You can move each type within its own category, but
cannot move one to either of the other categories. Each track, bus, and output has a
header with its icon, name, and a set of controls.
Tracks
Tracks contain the audio you add to your project in the Timeline. Each track has a drag
handle, a name, an icon, and a set of controls that appear in the track’s header in the
Timeline and in its channel strip in the Mixer. Track controls include a volume slider, a
pan control, an output pop-up menu, and buttons to mute or solo the track, add
effects, and enable the track for recording. In addition, each channel strip includes
stereo level meters you can use to watch the track’s levels, and a set of effects slots
where you can add and order track effects and sends.
