Gain Adjust
To adjust the gain of a .WAV file, you must first select a time segment. This is done from either the Time Series, Spectrogram, or 3-D Surface plot. Click the selection arrow located on the plot 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><Gain Adjust> menu command. You will then be prompted enter the the amount of gain in decibels (dB) to add or subtract. Click the OK button to perform the adjustment.
Notes:
The <Edit><Undo Edit> menu command will restore the segment to its previous value.
