This value determines the buffer
characteristics for transfers to and from
the disk. Changing this value does not
affect audio latency, but will affect the
disk throughput for audio tracks. The
default setting is 64. If you have audio
problems, try 32 and then 16. If audio
problems persist, try 128, 256, 512, or
reset to 64 and try a different remedy.
Check this option if your audio hardware
is supposed to support simultaneous
record and playback, but for some reason
is unable to do so.
A driver underrun results when your
computer cannot fill the audio buffers in
the amount of time allotted. You can
choose whether Cakewalk stops
playback or keeps playing when this
occurs.
In general, enable this option if you are
trying to achieve the lowest possible
latency that your sound card is capable
of.
When this option is enabled, Cakewalk
will "clip" every mixed output sample
instead of letting it "wrap," or overflow.
This often reduces the audible results of
mixing too hot, and creates a warmer,
more pleasing type of distortion when
you overdrive tracks. You may find it
especially useful on guitar-heavy mixes.
Enabling this option adds more overhead
to the mix engine, so you may notice a
reduction in the maximum number of
playable tracks.
You can use this option when you import
24-bit audio into a 16-bit project. The
dither signal is added to the 16-bit signal
to approximate what the 24-bit signal
would sound like. This effect is not
usually heard by most people, and it adds
processing time. You can disable it during
mixing and enable it during mastering.
Disabling this option may provide a slight
improvement in real-time effects
performance.
