CHAPTER 30. COMPUTER AUDIO RESOURCES AND STRATEGIES 511
For frozen Session clips, only two loop cycles are included in the frozen clip, which means
that clips with unlinked clip envelopes may play back differently after two loop cycles when
frozen.
The samples generated by the Freeze Track command are stored in your temporary recording
folder until you save your Live Set, at which point they are moved to the following project
folder sub-directory: Samples/Processed/Freeze. Please note that freeze les for tracks that
contain an External Instrument or External Audio Effect will be discarded immediately when
unfreezing.
You can also decide to atten frozen tracks, which completely replaces the original clips and
devices with their audible result. The Flatten command is available from the Edit menu.
Besides providing an opportunity to conserve CPU resources on tracks containing a large
number of devices, the Track Freeze command simplies sharing projects between comput-
ers. Computers that are a bit low on processing power can be used to run large Live Sets as
long as any CPU-intensive tracks are frozen. This also means that computers lacking certain
devices used in one Live Set can still play the Set when the relevant device tracks are frozen.
30.2 Managing the Disk Load
A hard drive's access speed (which is related to, but not the same thing as rotational speed)
can limit Live's performance. Most audio-optimized computers use 7200 RPM or faster
drives. Laptops, to save power, often use 5400 RPM or slower drives, which is why projects
on laptops usually have lower track counts. The amount of disk trafc Live generates is
roughly proportional to the number of audio channels being written or read simultaneously.
A track playing a stereo sample causes more disk trafc than a track playing a mono sample.
The Disk Overload
Indicator.
The Disk Overload indicator ashes when the disk was unable to read or write audio quickly
enough. When recording audio, this condition causes a gap in the recorded sample; when
playing back, you will hear dropouts.
