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. Sample-based
Elastic Audio-enabled tracks let you apply real-
time or rendered Elastic Audio processing by ed-
iting in Warp view, applying Quantize, and us-
ing the TCE Trimmer tool. However, only tick-
based Elastic Audio tracks also automatically ap-
ply Elastic Audio processing based on tempo
changes in the session.

To enable Elastic Audio on a track:

1

Create a new audio track or choose an existing

audio track.

2

Click the track’s Elastic Audio Plug-in selector,

and select the Elastic Audio plug-in appropriate
to your track material and the results you want
from the pop-up menu: Polyphonic, Rhythmic,
Monophonic

, Varispeed, or X-Form (see “Elastic

Audio Plug-ins” on page 774).

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.

To have all new tracks be tick-based, enable
the New Tracks Default To Tick Timebase
option in the Editing preferences.

When creating new tracks by dragging and
dropping audio from a DigiBase browser, if
the Audio Files Conform to Session Tempo
option is enabled, Pro Tools creates tick-
based Elastic Audio-enabled tracks regard-
less of whether the Elastic Audio analyzed
file is tick-based or sample-based. If the Au-
dio Files Conform to Session Tempo option
is not enabled, Pro Tools creates regular
sample-based tracks.

With Pro Tools HD, Elastic Audio is disal-
lowed on voiced tracks. Use dynamic voice
allocation for tracks on which you want to
use Elastic Audio. (Pro Tools LE only sup-
ports dynamic voice allocation, and cannot
specifically allocate individual voices.)
