To destructively edit an audio waveform with the
Pencil tool:
1
Locate the area you want to edit.
2
Using the Zoomer tool or the Zoom buttons,
zoom down to the sample level so the waveform
appears as a continuous thin line. Adjust the
Track Height, as necessary, to edit the waveform
with greater precision. You can also use vertical
zoom for greater visual resolution.
3
Select the Pencil tool.
4
Carefully draw with the Pencil tool by drag-
ging over the area of the waveform.
Do not over-edit or the results may be undesir-
able. However, you can use the Undo command
to undo your previous edit.
Try to limit editing to smoothing over a very
small problem area, and keep the “fixes” in
character with the shape of the surrounding
waveform.
Region Groups
A region group is a collection of any combina-
tion of audio and MIDI regions that looks and
acts like a single region. Region groups are essen-
tially containers holding one or more regions.
Region groups can be created on a single or on
multiple adjacent audio, MIDI, and Instrument
tracks. Region groups let you “nest” multiple re-
gions into “macro” regions for groove and
tempo manipulation, editing, and arranging.
Region groups can be placed on tracks alongside
standard regions, and edited using many of the
same Pro Tools editing techniques. Certain edits
to a region group will apply to all regions con-
tained by the region group, such as Cut or De-
lete. Other edits only apply to the boundaries of
the region group and do not affect the underlin-
ing regions, such as Trim.
Each region group is saved with the session as a
Region Group file (.rgrp). Region Group files can
be exported from and imported into different
Pro Tools sessions.
You can recall zoom levels with the Zoom
Preset buttons (see “Using the Zoomer
Tools” on page 367), or with Memory Loca-
tions (see “Memory Locations and Markers”
on page 524).
Pencil tool
Repairing a “pop” with the Pencil tool
If you have trouble zooming in far enough to
perform Pencil tool editing, check the Edit
window (session) length. Shorten the overall
Edit window (session) length, if possible,
until the Pencil tool becomes usable.
