Place the track to be faded out above the track to be faded in then select the overlapping region in both tracks and apply the effect.

Crossfade Tracks: Use Crossfade Tracks to make a smooth transition between two overlapping tracks one above the other.

Crossfade Clips: Use Crossfade Clips to apply a simple crossfade to a selected pair of clips in a single audio track.

Normalize: Use the Normalize effect to set the maximum amplitude of a track, equalize the amplitudes of the left and right channels of a stereo track and optionally remove any DC offset from the track.

It is based on EBU R 128 recommendations on limiting the loudness of audio signals.

Loudness Normalization: Normalizes for loudness and RMS, changes the level of the audio (normally reduce it to recommended limits).

Mastering engineers often use this type of dynamic range compression combined with make-up gain to increase the perceived loudness of an audio recording during the audio mastering process.

Limiter: Limiter passes signals below a specified input level unaffected or gently reduced, while preventing the peaks of stronger signals from exceeding this threshold.

Make-up gain can be applied to either method, making the result as loud as possible without clipping, but not changing the dynamic range further.

The alternative 'peaks' method makes the entire audio louder, but amplifies the louder parts less than the quieter parts. The default ' RMS' method makes the louder parts softer, but leaves the quieter audio alone.

Compressor: Compresses the dynamic range by two alternative methods.

Typically used to make a music track softer whenever speech in a commentary track is heard.

Auto Duck: Reduces (ducks) the volume of one or more tracks whenever the volume of a specified 'control' track reaches a particular level.

Amplify: Increases or decreases the volume of the audio you have selected.
