How to fade audio in or out

Choose the edge you want to smooth

A fade-in raises the level from the start of the section. A fade-out lowers the level as it approaches the end. In Recorte individual (single trim), open a WAV or MP3 and set its edges first. Enter the length in Fundido de entrada (segundos) (fade-in, seconds) or Fundido de salida (segundos) (fade-out, seconds). In Montaje (session), those controls appear when you select a clip.

A 0.3 s fade-out can soften the end of a vocal sample. On an intro that starts with a kick, begin with a shorter setting to keep the attack. Always listen with the audio you are actually going to use.

Adjust in context

Listen to the start and the end with Escuchar edición (play edit) in single trim, or play the clip in its session. If the fade swallows a syllable or a hit, shorten it. If a click remains at the end, lengthen the fade a little or move the cut to a point with less signal.

Each fade has to fit inside the length of the trim. If you want to go from one sound to another with both playing at once, prepare the overlap on two tracks and use a crossfade.

Save the result

Download the WAV from single trim or export the mix from session mode. Listen to the exported file at the point you changed to check the edge.
