The following tools, which are the most commonly used tools for editing, can be accessed from the Toolbar at the top of the interface.

Moves clips in the Timeline. Clips can be moved left-right to change their timing, as well as up-down to different tracks.

Cuts clips into separate portions that can be independently moved and edited in the Timeline. This tool wont delete or modify audio from the original file or recording.

Selects portions of clips in the Timeline. Click-and-drag within the Timeline to select.

To trim a clip, click-and-drag the ends inward/outward. Dragging inward will shorten the clip, and outward will lengthen.

Moving
To move a clip within the Timeline, click-and-drag it with the Move Tool. Clips can be moved left/right to change their timing, as well as up-down to different tracks.

Splitting a clip separates it into smaller portions, which can be edited independently of each other. This allows portions of long clips to be divided, isolated, moved, or deleted. When splitting a clip in the Timeline, the original file or recording will remain unaltered and can be retrieved from the Files panel at any time. To split clips in the Timeline, select the Razor Selected Clips Tool from the Toolbar and click the desired location of the clip. The original clip will be split into two separate clips.

Deleting
To delete a clip, select it and press the Delete key. To delete a portion of the clip, use the Razor Tool to cut out the section, select the new subclip, and press the Delete key.

The volume levels of clips can be adjusted throughout the Timeline. Adjusting volume is necessary to make sure essential audio is audible and understandable. Keyframing is a technique that can be used to duck audio, which is the practice of fading clips in-or-out. Audio ducking can be used to fade background music, as well as to fix the levels of voices such as yells and whispers. Keyframes are snapshots of the clips volume level at a single moment; when a clip has multiple keyframes at different levels and times, Audition will automatically transition the volume between them. For example, keyframes at 0db and 6db respectively will create a fade-in, and keyframes at 6db and 0db respectively will create a fade-out.
