Visually fading and changing amplitude

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.

To quickly fade selected audio, choose Favorites > Fade In or Fade Out.

    Visually fade in or out

    Adobe 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 smoothly change volume 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, see Fade or crossfade multitrack clips.

    Logarithmic

    C.
    Cosine

     In the upper left or right of the waveform, drag the Fade In  or Fade Out  handle inward, and do any of the following:

    • 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 (Mac OS).

    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

    1. In the Editor panel, select specific audio, or select nothing to adjust the entire file.
    2. 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 in one 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.
