Multichannel Clips These clips, which are dis-
played as a single clip in the Clip List, reference
multiple clips and audio files for stereo and sur-
round tracks. Multichannel clips can be expanded
(by clicking the triangle next to their name) to see
the individual channels, which can be dragged in-
dependently to tracks.
Clip Groups A clip group is a collection of any
combination of audio and MIDI clips that looks
and acts like a single clip. Clip groups are essen-
tially containers holding one or more clips. Clip
groups can be created on a single track or on mul-
tiple adjacent audio, MIDI, and Instrument tracks.
Clip groups let you “nest” multiple clips into
“macro” clips for groove and tempo manipulation,
editing, and arranging (see “Clip Groups” on
page 847).
Warped Clips Clips on Real-Time Elastic Audio-
enabled tracks can be warped. Warped clips are
identified with a Warp Indicator icon in the upper-
right corner of clips on tracks and to the left of clip
names in the Clip List. Warped clips result from
the application of Elastic Audio processing. Elastic
Audio processing can be applied manually in Warp
view or using the TCE Trim Tool in Waveform
view, or automatically using tempo conform,
quantization, or transposition (see “Warped Clips”
on page 892).
Audio Clips and Waveforms
When the Track View for audio tracks is set to
Waveform, Pro Tools draws a waveform diagram
of the audio. Audio waveforms tell you several
things about the recorded sound.
In the figure above, the “peaks” represent places in
the recording where the attack of the sound causes
the volume to increase momentarily. These are fol-
lowed by “valleys,” where the volume decreases.
Different types of sounds produce different types
of waveforms. Drums, for example, generally pro-
duce 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 synthe-
sizer pads, produce very different waveforms.
These sounds have less pronounced peaks and val-
leys because they generally have softer attacks and
longer decays.
Waveform Views
Pro Tools provides a several different Waveform
View options. Depending on the editing task, you
may want to display waveforms in any number of
different ways.
