In the Audio Files workspace, open the audio file that you want to check for 
DC offset and fix.

Select Process > Remove DC offset.

Time stretching is an operation that allows you to change the length of a recording 
without affecting its pitch.

With time stretching you can make audio material longer or shorter. This function is 
most often used to make a section of audio fit in with some other material. You 
select the material to be stretched and use the options in the Time stretching 
dialog to find a stretch factor. This is done by specifying a length or a tempo, 
according to what the situation requires.

In this dialog, you can change the duration of an audio selection, usually without 
changing its pitch. You can stretch a selection to a specified duration (in minutes, 
seconds, and milliseconds), tempo (in bpm), or stretch factor (as percentage).

In the Audio Files workspace, select Process > Time stretching.
