Level

Gain

Opens the Gain dialog where you can apply a gain to change the level of an audio file.

Envelope

Opens the Envelope dialog where you can create a level envelope which can be applied to a selected range or an entire audio file.

This is useful if you want to even out loud and quiet parts or create a sophisticated fade in/fade out, for example.

Remove DC Offset

DC offset in a file affects the loudness. Remove DC Offset sets the DC offset to zero.

Level: Opens the Level Normalizer dialog where you can change the peak level of an audio file.
Loudness: Opens the Loudness Normalizer dialog where you can specify the loudness of a file.
Pan: Opens the Pan Normalizer dialog which allows you to ensure that both channels of a stereo file have the same level or loudness, and helps you to get the best possible stereo balance.

Fade In/Fade Out

Allows you to apply a fade in or fade out. Right-click the button to open the Curve pop-up menu.

Curve

Allows you to select preset fade curves.

Linear changes the level linearly.
Sinus (*) changes the level according to a sine curve. When used in a crossfade, the loudness (RMS) remains constant during the transition.
Square-Root (*) changes the level according to a square-root curve. When used in a crossfade, the loudness (RMS) remains constant during the transition.
Sinusoid changes the level according to a sine curve.
Logarithmic changes the level according to a logarithmic curve.
Exponential changes the level according to an exponential curve.
Exponential+ changes the level according to a more pronounced exponential curve.

Time Stretching: Opens the Time Stretching dialog where you can change the duration of an audio selection.
Pitch Shifting: Opens the Pitch Shifting dialog where can change the pitch of your audio.
Resample: Opens the Sample Rate dialog where you can change the sample rate of your audio.
Pitch Bend: Opens the Pitch Bend dialog where you can gradually change the pitch of your audio using an envelope curve.
Reverse: Creates a backwards-tape effect.

Tweaker: Opens the Loop Tweaker dialog where you can adjust the loop start and end points, and crossfade the loop boundaries.
Tone Uniformizer: Opens the Loop Tone Uniformizer dialog where you can create loops from sounds that are not optimal for looping.

Auto Split: Opens the Auto Split dialog where you can specify how to split clips.

Invert Phase: Turns the signal upside down.
Effect Morphing: Opens the Effect Morphing dialog, where you can gradually mix two audio ranges that have different effects/processing applied to them.
External Tools: Allows you to execute and configure external tools.
