EnableCacheWriteThru=<0 or 1>, default = 1
This Aud.ini variable enables disk write thru caching, on by default. When write thru caching is on,
data recorded to wave files is written to the hard disk immediately, circumventing the hardware disk
cache. Having write thru caching off can be more efficient for disk I/O but can result in data loss if
your system crashes.
MIDI Prepare Buffer Size and automation
If your project contains several track/clip automation envelopes, setting your MIDI playback buffer
size too low (in Options > Global > MIDI) can cause audio to crackle if your audio latency is also set
very low. This problem will be somewhat worse if you enable multiprocessing in the audio engine. To
minimize or eliminate these crackles, please be sure to keep your MIDI playback buffers at or above
the default setting of 500 msec.
