Learn how to apply fades and adjust amplitude visually in Adobe Audition to create smooth transitions and control audio levels with precision.
Though various effects can change amplitude or produce fades, visual fade and gain controls make the task quick and intuitive. As you drag these controls in the Editor panel, a preview helps you precisely adjust audio.
A. Fade controls B. Gain control (heads-up display)
Note
To quickly fade selected audio, choose Favorites > Fade In or Fade Out.
Visually fade in or out
Audition offers three types of visual fades:
Linear fades produce an even volume change that works well for much material. If this fade sounds too abrupt, however, try one of the other options.
Logarithmic fades change volume smoothly, slowly, and then rapidly, or vice versa.
Cosine fades are shaped like an S-curve, changing volume slowly at first, rapidly through the bulk of the fade, and slowly at the finish.
Note
In the Waveform Editor, fades permanently change audio data. To apply fades, you can readjust in the Multitrack Editor.
A. Linear B. Logarithmic C. Cosine
For a linear fade, drag perfectly horizontally.
For a logarithmic fade, drag up or down.
For a cosine (S-curve) fade, hold down Ctrl (Windows) or Command (macOS).
Note
To create cosine fades by default and hold the keys above to create linear or logarithmic fades, change the Default Fade setting in the General preferences.
Visually raise or lower amplitude
In the Editor panel, select specific audio, or select nothing to adjust the entire file.
In the gain control that floats above the panel, drag
the knob or numbers.
The numbers indicate how new amplitude compares with existing amplitude. When you release the mouse button, the numbers return to 0 dB, so you can make further adjustments.
Pin or hide the visual amplitude control
By default, the visual amplitude control appears in a heads-up display (HUD) that floats over all waveforms. If you find the HUD distracting, do any of the following:
To lock the HUD to a single location, click the Pin button
.To show the HUD only over highlighted selections, select Show HUD for selection ranges only in the General preferences.
To totally hide the HUD, deselect View > Show HUD.
