Trimming Length of a Soundfile

Suppose there are exactly 3 minutes left on your recordable CD and the recording you would like to include is 3 minutes and 5 seconds long ... The easiest way to cope with such a situation is to 'shorten' the material while keeping the original sampling rate unchanged. Of course, all length alterations affect the pitch of the audio signal. However, if the changes are not significant, e.g., if the new length does not differ by more than +/- 5% from the old one, pitch variations remain practically unnoticeable.

The Trim length utility allows you to freely adjust the length of the recording by means of specifying the new length expressed in time units, bytes or as a percentage rate. If the attempted changes are not cosmetic, i.e. they exceed the +/- 5% safety margin, the red 'safety alert' light is turned on to warn you of possible hazards.
