DAE Playback Buffer Size
The DAE Playback Buffer Size determines the
amount of memory DAE allocates for disk buff-
ers. The optimum DAE Playback Buffer Size for
most disk operations is Level 2.
DAE Playback Buffer Size settings lower than
◆
Level 2 may improve playback and recording
initiation speed, but may make it difficult to
play or record tracks reliably with sessions con-
taining a large number of tracks or a high den-
sity of edits, or with systems that have slower or
heavily fragmented hard drives.
DAE Playback Buffer Size settings higher than
◆
Level 2 will allow for a higher density of edits in
a session or a higher track count when using
slower hard drives. However, a higher setting
can also cause a time lag to occur when starting
playback or recording, or longer audible time lag
while editing during playback.
Using a larger DAE Playback Buffer Size
leaves less system memory for other tasks.
The default setting of Level 2 is recom-
mended unless you are encountering -9073
("Disk too slow or fragmented") errors.
To change the DAE Playback Buffer Size:
Choose Setup > Playback Engine.
1
From the DAE Playback Buffer pop-up menu,

select a buffer size.
Click OK.
