Chapter 90: Time
Compression/Expansion
Time Compression/Expansion is an AudioSuite
time-processing plug-in.
The Time Compression/Expansion plug-in ad-
justs the duration of selected clips, increasing or
decreasing their length without changing pitch.
It is especially useful in audio post production
for adjusting audio to specific time or SMPTE
durations for synchronization purposes. Time
Compression/Expansion is nondestructive.
Time Compression/
Expansion Controls
The Time Compression/Expansion plug-in pro-
vides the following controls:
Source and Destination The Source fields dis-
play the length of the current selection before
processing in each of the listed formats. All
fields are always active; a change made to one
value is immediately reflected in the others.
The Destination fields both display and control
the final length of the selection after processing.
Enter the length of the Destination file by dou-
ble-clicking the appropriate field in the Destina-
tion column.
Use the Ratio, Crossfade, Min Pitch, and Accu-
racy controls to fine-tune the Time Compres-
sion/Expansion process.
Ratio Sets the destination length in relation to
the source length. Moving the slider to the right
increases the length of the destination file, while
moving the slider to the left decreases its length.
Crossfade Adjusts the crossfade length in milli-
seconds, optimizing performance of the Time
Compression/Expansion according to the type
of audio material being processed. (This plug-in
achieves length modification by replicating or

Normalizing a selection before using Time
Compressing/Expansion may produce better
results.
