Muting a time segment will set the values to zero.
To mute a segment of a .WAV file, you must first select a time segment. This is done from either the Time Series, Spectrogram, or 3-D Surface view. Click the selection arrow located on the view toolbar and then click and drag the mouse across the desired time segment. This segment will then be displayed in inverse video. Once the time segment has been selected, select the <Edit><Mute> menu command. The samples corresponding to the selected time segment will be set to zero.
The <Edit><Undo Edit> menu command will restore the data to its original values.
