Multitrack sessions can include four different types of tracks:
Video tracks contain an imported video clip. A session can include one video track and clip at a time. You can watch a preview in the Video panel (Window > Video).
Audio tracks contain either imported audio or clips recorded in the current session. These tracks offer the widest range of controls. You can specify inputs and outputs, apply effects and equalization, route audio to sends and buses, and automate mixes.
Bus tracks let you combine the outputs of several audio tracks or sends and control them collectively.
The Mix track , which is the last in each session, lets you easily combine the outputs of multiple tracks and buses. You can also control them with a single fader.
For more information, see Routing audio to buses, sends, and the Mix track.
Multitrack sessions support an unlimited number of mono, stereo, and 5.1 audio and bus tracks. When adding tracks, choose a channel configuration based on the configuration of the Mix track:
For mono mix, add mono audio and bus tracks.
For stereo mix, add stereo audio and bus tracks. Except for audio tracks with mono sources (like a single microphone).
For 5.1 mix, add stereo audio tracks and 5.1 bus tracks (to maintain proper gain staging). If you have any 5.1 audio clips, however, add 5.1 audio tracks to contain them.
A. Mono B. Stereo C. 5.1
For information about converting a waveform between surround, stereo, and mono, see the following:
A multitrack session supports only one video track, which Adobe Audition always inserts at the top of the Editor panel.
To add a track, select the track you want to precede it, and then choose Multitrack > Track > Add [type of] Track.
To delete all empty tracks at once, select Multitrack > Delete empty tracks.
For more information, see the following:
You can name tracks to better identify them, or move them to display related tracks together.
While working on the multitrack editor, you can use the Tracks panel to customize tracks. You can use the panel to choose the tracks you want to see or hide while working on a project. To open the Tracks panel, follow this step:
Use Track Visibility to see the available presets for tracks. To open Track Visibility options, do one of the following:
To save custom presets, select Track Visibility > Save > Preset. You can save up to nine presets.
To hide tracks, use the eye icon. indicates that the track is visible, and indicates that the track is hidden.
When you use the vertical Zoom options in the lower right of the Editor panel, all tracks zoom simultaneously. If a session contains many tracks, it is advised to zoom them individually.
To quickly zoom all tracks, roll the mouse wheel over the track controls. To horizontally resize all track controls, drag the right border.
For more techniques, see Zoom audio in the Editor panel.
You can mute solo tracks to hear them separately from the rest of a mix. Conversely, you can mute tracks to silence them in a mix.
Tip: To remove other tracks from Solo mode by default, select Track Solo: Exclusive in the Multitrack section of the Preferences dialog box. (Regardless of this setting, when you solo a bus, assigned tracks are always placed in Solo mode.)
To increase your efficiency, you can quickly apply several settings to an entire session.
For more information, see the following:
In the Editor panel, drag the Volume knob . To change settings in large increments, hold down Shift. To change settings in small increments, hold down Ctrl (Windows) or Command (Mac OS)
In the Mixer, drag the track fader, or click above or below to move incrementally to the next tick mark. To move to a specific point, Alt‑click (Windows) or Option-click (Mac OS) above or below the fader.
To return knobs and faders to zero (unity gain), Alt‑click (Windows) or Option-click (Mac OS) directly on them.
To change settings in large increments, hold down Shift. To change settings in small increments, hold down Ctrl (Windows) or Command (MacOS)
Tip: By default, the Multitrack Editor pans using an equal power method, which maintains consistent perceived loudness by slightly boosting one channel over the other. To change the boost amount, or switch to logarithmic panning (which simply attenuates one channel), change Panning Mode in the Multitrack preferences.
To perfectly copy all clips, effects, equalization, and envelopes in a track, duplicate it. Duplicate tracks provide a great starting point for new adjustments, helping you compare different processing and automation settings.
