Freeze tracks and synths
The Freeze feature allows you to temporarily bounce your track, including soft synths and effects, to reduce the amount of CPU power needed. The Freeze feature also works for synths patched in the Synth Rack.
The following are the available commands for track freezing:
Freeze Track. Bounces the audio in the track to a new audio clip or clips, applies any effects,
and disables the effects bin.
Unfreeze Track. Discards the bounced audio, restores the original audio to the way it was before the last Freeze or Quick Freeze command, and enables the effects bin.
Quick Unfreeze Track. Hides and mutes the bounced audio, restores the original audio to the way it was before the last freeze or quick freeze command, and enables the effects bin. Bounced audio is retained, however, and toggling between Quick Freeze and Quick Unfreeze should be
instantaneous.
Quick Freeze Track. Only available after a Quick Unfreeze, the Quick Freeze function redisplays and unmutes the bounced audio instantaneously and disables the effects bin.
The following are the available commands for synth freezing:
Freeze Synth. Audio from a soft synth is bounced and placed on the synths track. Output from the synth is disabled, as is the effects bin on the synth track.
Unfreeze Synth. Discards bounced audio, enables the synth and track effects bin. Bounced audio is discarded, and will be re-bounced if you choose Freeze again.
Quick Unfreeze Synth. Hides and mutes the bounced audio, enables the synth and track effects bin. Bounced audio is retained, and toggling between Quick Freeze and Quick Unfreeze should be instantaneous.
Quick Freeze Synth. Only available after a Quick Unfreeze, the Quick Freeze function redisplays and unmutes the bounced audio instantaneously, disables the synth, and any effects on the synth track.
Note 1: An Unfreeze or Quick Unfreeze command restores the audio on a track to the way it was before the last Freeze or Quick Freeze command. Any editing you do to a frozen track is discarded when you Unfreeze or Quick Unfreeze the track.
Note 2: You control the bit depth of all rendering operations (bouncing, freezing, applying effects) in Edit > Preferences > File - Audio Data, in the Render Bit Depth field. The default value of 32 is the best for most situations. See Bit depths for rendering audio on page 1112 for
more information.
