Re: 11.1 and 11.2... still getting CPU spikes?!
Hello good people.
I am new to the DUC forum, so please forgive any transgression of responder protocols, such as being too verbose. I have found a pretty reliable workaround to this deeply frustrating flaw, in an otherwise exquisite program. My observations were that plugins acting on audio regions with little or no audio, try to amplify that audio, and the resolution required to do that places a heavy load on the processor causing the spikes. The first work around I found was to insert the Dither plugin at the top of any channel that involved amplification such as Sans Amp PSA, or Eleven. I thought this worked because noise produced by the Dither plugin, although inaudible stopped the plugin trying to process silence and thus prevented the massive processor allocation. But then I noticed that even compressors and limiters had the same effect, causing processor spikes. So work around two was to insert a dither plugin at the top of every channel. This was even more reliable than the previous workaround and pretty much allowed un interrupted work. As I was working with this fix, I wondered if the accumulative effect of all these plugins would result in some kind of audible artefact, so I tried globally bypassing the entire Dither plugin set, and yes there is an audible difference, (actually not a bad difference but a difference none the less). And that led to fix number three. Run with all the Dither plugins in bypass. Don't ask me why it works, it blows my theory out of the water, but on all my systems it does. The Dither plugin uses very little system resources so doesn't really limit the availability of other plgingins. I'll be curious if others find this works for them. I hope this helps Ben |

Your "Dither First" idea is for Denormalization. Be interesting if that's the issue - or one of them.
