Displaying Region Names
and Times
Region names can sometimes get in the
way of editing audio waveforms and MIDI
data. In these instances you may want to
disable their display.
To disable the display of region names in
playlists:
■ Deselect Display > Display Name In Re-
gions.
You can choose to display region time code
locations in the playlist area. This is ex-
tremely useful when working with film and
video.
To display region times:
■ From Display > Display Time In Regions,
select one of the following options:
None Disables display of region times.
Current Time Displays start and end times
for regions.
Original Time Stamp Displays the Original
Time Stamp for each region. The Original
Time Stamp is the original time code loca-
tion for the region when it was first re-
corded or created.
User Time Stamp Displays the User Time
Stamp for each region. The User Time
Stamp, which default to the Original Time
Stamp, can be redefined with the Time
Stamp Selected command.
Audio Regions and
Waveforms
When the Display Format for audio tracks
is set to Waveform, Pro Tools draws a wave-
form diagram of the audio. Audio wave-
forms tell you several things about the re-
corded sound.
Figure 6 shows an audio waveform for a
drum loop. The “peaks” represent places in
the recording (beats) where the attack of
the sound causes the volume to increase
momentarily. These are followed by “val-
leys,” where the volume decreases.
Different types of sounds produce different
types of waveforms. Drums, for example,
generally produce waveforms with sharp
transients (peaks of short duration) that are
clearly defined. A drum hit has a loud,
sharp attack and a rapid decay.
Other sounds, such as vocals or sustained
keyboard sounds, produce very different
waveforms, ones that have less pro-
nounced peaks and valleys. That’s because
these sounds generally have softer attacks
and longer decays.

Waveforms Rectified is selected, audio
