Gain Dialog

• To open the Gain dialog, select the Process tab in the Audio Editor, and click Gain in the Level section.

1. Gain in dB

   Increases or decreases the audio level by the value you enter here.

2. Crossfade Type

   Allows you to choose from the following options:

   • No Crossfade adds the specified gain value to the entire audio range, without generating crossfades at its beginning or end.

   • Inner Crossfade adds the specified gain value to the entire audio range and generates crossfades at its beginning and end, within the selected range.

   • Outer Crossfade adds the specified gain value to the entire audio range and generates crossfades at its beginning and end, outside the selected range, As a result, the audio inside the range is affected by the change in gain, but not by crossfading, whereas the audio outside the range remains unaffected by the change in gain, but crossfading takes effect on its boundaries.

     Note

     You can make global adjustments for the length and the shape of crossfades by selecting File > Preferences > Global. Clicking the Audio tab provides you with access to the options for fading and crossfading.

     Note

     WaveLab automatically recognizes whether the gain adjustment is applied to the start or to the end of an audio file and sets the crossfades accordingly:

     • If you apply a gain change to the start of a file, WaveLab exclusively generates a crossfade at the right boundary.

     • If you apply a gain change to the end of a file, WaveLab exclusively generates a crossfade at the left boundary.

Find Current Peak Level generates a report on the peak level of the audio selection, or on the whole file, if there is no selection. This allows you to calculate how much you can increase the overall gain of a file without clipping (exceeding 0 dB), for example.
