Normalize

Normalizes the selected part of an audio file.

Parameter	Description
Trim Level	Normalization coefficient. Varies from 0 to 100. The percentage of maximum to which you want to normalize. For example, choose 50% to compute values needed to amplify the selection no more than 50% of maximum.
Fade Time	Can be Selected (leveling) or Unselected (not leveling).

Tip:

See also: Apply a Special Effect or Filter
Amplifies the selection part to within the specified percentage of the maximum level.

This function enables you to achieve the greatest amount of amplification that will not result in clipping. To normalize to less than the maximum range enter the percentage of maximum to which you want to normalize. For example, if you choose 50%, Audio Editor will compute values needed to amplify the file no more than 50% of maximum. If two sounds that have been normalized to 50% are overlapped, the resulting wave will not exceed the boundaries, and will not clip.
