Sound Design and Special Effects
Use Elastic Audio to achieve special effects with
extreme or widely variable TCE or pitch manip-
ulation. Use the Varispeed algorithm to achieve
tape-like effects for speed and pitch change.
Film Scoring
If you are scoring a film scene, use Elastic Audio
to fit the music to the required duration. You
can even use tempo changes to achieve accele-
randos and ritardandos.
Example Elastic Audio
Workflow
In this workflow, you will be introduced to some
common Elastic Audio tasks for working with
loops:
• Create and configure a new session for this
workflow.
• Locate and preview a loop in DigiBase at
the session tempo.
• Import the loop at the session tempo on a
tick-based, Elastic Audio-enabled track.
• Change the session tempo to change the
tempo of the region on tick-based, Elastic
Audio-enabled tracks.
• Quantize the audio to apply a Groove Tem-
plate to the rhythm.
• Transposition the region to match the
pitch of the imported audio to other audio
and MIDI in the session.
Create and configure a new session:
1 Create a new Pro Tools session.
2 Set the session’s Main Timebase ruler to
Bars|Beats.
3 Be sure to display the Tempo and Meter rulers.
4 Use the default tempo of quarter-note equals
120 BPM.
Remember, when using tempo adjustments
for sessions that include multiple cues,
tempo changes may affect the time code
position of other cues later on the Timeline.
Elastic Audio is not recommended for pull-
up and pull-down workflows. Use the
Session Setup window real time pull-up or
pull downs, or the presets included with
DigiRack Time Shift or X-Form AudioSuite
plug-ins.
