OPTIMIZING FOR SOUND FORGE CHP. 3
Increasing total buffer size
The total buffer size value determines the amount of RAM used for recording to/playing from the hard drive.
A total buffer size of 512 KB is recommended, but increased buffering may be necessary if you detect gaps
during playback.
Increasing the total buffer size
requires additional memory. Combined with a large preload size, this may
result in a delay when starting and stopping playback. For more information, see Increasing preload size on page
26.
1. From the Options menu, choose Preferences. The Preferences dialog appears.
2. Click the Wave tab.
3. Use the Total buffer size slider to configure an appropriate buffer size value and click OK.
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.
1. From the Options menus, choose Preferences. The Preferences dialog appears.
2. 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 meter s
Sound Forge’s play and record meters use a small amount of processing overhead during recording and
playback. However, if you detect dropouts during recording or playback and previous fixes have failed, try
turning off these meters.
