Calculating Waveform
Overviews
Waveforms can be calculated using Peak or Power
overviews.
To set how the Waveform view is calculated:
 Choose View > Waveforms and select Peak or
Power
Peak When selected, the waveform display is cal-
culated based on the sample-by-sample peak level.
Peak view is traditionally how Pro Tools calcu-
lates the waveform overview and can be used for
normal or rectified views. Peak view clearly dis-
plays any clipping in the waveform.
Power When selected, the wave form display is
calculated according to the Root Mean Square
(RMS). Power view can be used for normal or rec-
tified views. Power view is useful for better seeing
the characteristics of the audio in the waveform
representation when zoomed out beyond the sam-
ple level. For mastering applications in particular,
it can be more revealing of the sonic characteristics
of the audio than Peak view.
Normal Peak Waveform view with Outlines
When zoomed in to the sample level,
Pro Tools always displays Peak view.
Normal Power Waveform view with Outlines
Peak view is always shown during recording.
Power waveform view is calculated and
shown only after you stop recording.
Power view is not available in Destructive
Punch mode or when zoomed to the sample
level.
