There are some drawbacks to increasing the Total buffer size. It requires more of
your computer’s memory and, if you have set a large Preload size, there can be
small delays when starting and stopping playback.
PRELOAD SIZE
The Preload size option in the Wave page (Preferences folder, Options menu), tells
Sound Forge XP how much sound data it should prepare and load into your
sound card driver before starting playback. This preloading is performed
between the time you press the Play button and the time you hear the sound play.
Turning this option on may help skipping (audible gaps) on initial playback
of a sound.These gaps usually occur with slow or fragmented hard drives.The
trade-off for enabling this option is a slight delay before play begins; the delay
time is greater for larger preload sizes. This option does not affect operations
other than playing.
Some Windows sound drivers do not support this option correctly. If you are
experiencing noise or dropouts at the very start of playback, try disabling
this option.
PLAYBACK CURSOR AND RECORD COUNTER
The playback cursor and record counter options in the Performance page
(Preferences folder, Options menu) allow you to configure whether or not the
numeric counters (position information displayed in status fields) will be
updated during playing and recording. If you are recording or playing at high
sample rates (44,100 or 48,000 Hz) and are experiencing gapping or skipping
problems in the data, try disabling the playback cursor and/or record counters
to decrease overhead.
METERS
The Record Meters in Sound Forge XP take a small amount of processing
overhead during recording. If you hear gaps in the sound while recording
and you have the Monitor option enabled in the Record dialog (Transport
command, Special menu), try turning off the Record Meters by clearing the
Monitor check box.
