OPTIMIZING FOR SOUND FORGE CHP. 2
Increasing preload size
The preload size value determines how much sound data Sound Forge prepares and loads into the sound card
driver prior to starting playback. Preloading occurs between the time you click the
Play button ( ) and the
first sound of playback.
Increasing preload size may eliminate the dropouts evident at the beginning of playback that are
characteristic of slow and/or fragmented hard drives. The trade-off for increasing the preload size is a delay
prior to the start of playback. The length of the delay is proportional to the size of the preload.
1.
From the Options menu, choose Preferences. The Preferences dialog appears.
2.
Click the Wave tab.
3.
Use the Preload size slider to configure an appropriate preload size value and click OK.
Note:
Certain Windows sound drivers do not support this
option. If you detect noise or dropouts at the start of playback
and the system’s sound drivers do not support preloading,
turn off this option by setting the Preload size to 0.
Turning off the playback cursor and record counter
The playback cursor and record counter options determine whether these displays are updated during
recording and playback. If you detect dropouts and skipping at high sample rates (greater than 44,100 Hz),
turn these displays off to minimize processing overhead.

Click the Perform tab.
3.
Clear the Show the position of the playback cursor and Show the record counter while recording check boxes and
click
OK.
Turning off the play (output) meters
Sound Forge’s play meters use a small amount of processing overhead during playback. However, if you
detect dropouts during playback and previous fixes have failed, try turning off these meters.
From the
View menu, choose Play Meters. The check mark adjacent to the command is cleared, indicating
that the play meters are turned off.
Turning on passive updating for video and time displays
Passive update options lower the priority of redrawing the video and time displays during playback. When
these options are turned on, the displays update only if there is ample time. Frequently this goes unnoticed,
and enabling these options minimizes playback overhead with little or no inconvenience.
Turning on passive updating for time displays
From the Options menu, choose Time Display, and choose Passive Update from the submenu. A check mark
appears next to the command to indicate that this option is turned on.
