Time Compression/Expansion
(AudioSuite Only)
The Time Compression/Expansion plug-in ad-
justs the duration of selected regions, 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.
Source and Destination The Source fields display
the length of the current selection before pro-
cessing 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
subtracting very small portions of audio mate-
rial and very quickly crossfading between these
alterations in the waveform of the audio mate-
rial.)

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