Quality
Select either Maximum or Low (Faster) from the
Quality pop-up menu. Maximum is the slowest
processing algorithm, but provides the highest
quality results. Low (Faster) produces relatively
good results and is much faster than the Maxi-
mum setting.
Formant
For audio material with clear formants, enable
Formant to preserve the formant shape of audio
when applying TCE processing.
Elastic Audio Tracks
Any audio track in your Pro Tools session can be
Elastic Audio enabled. Elastic Audio tracks can
be either sample- or tick-based. However, only
tick-based Elastic Audio tracks automatically ap-
ply TCE based on tempo changes.
To enable Elastic Audio on a track:
1 Create a new audio track or use an existing au-
dio track.
2 From the track’s Elastic Audio Plug-in selector,
select the Elastic Audio plug-in appropriate to
your track material.
Any audio regions on the track temporarily go
offline while they are analyzed and come back
online when the analysis is finished. The wave-
form for audio regions that are offline for Elastic
Audio analysis appears grayed out.
When recording to a real-time Elastic Audio–en-
abled track, once recording is stopped, the
newly recorded audio temporarily goes offline
while it is analyzed and comes back online as
soon as the analysis is finished.
Audio with a fundamental pitch has an
overtone series, or set of higher harmonics.
The strength of these higher harmonics cre-
ates a formant shape, which is apparent if
viewed using a spectrum analyzer. The over-
tone series, or harmonics, have the same
spacing related to the pitch and have the
same general shape regardless of what the
fundamental pitch is. It is this formant
shape that gives the audio its overall char-
acteristic sound or timbre. When pitch
shifting audio, the formant shape is shifted
with the rest of the material, which can re-
sult in an unnatural sound. Keeping this
shape constant is critical to formant correct
pitch shifting and achieving a natural
sounding result.

Elastic Audio, see the Pro Tools Reference
Guide.
