I agree. The more efficient and faster you make the cycle time minimums in a program, as you are taxing the software with more options and plugins and the like, each little millisecond counts. And when you cannot count on the OS to give you low latency in itself, it makes your efforts futile.

Going back to the issue of latency, it should be pointed out that while it might not be a big deal if your softsynth takes 25 ms to trigger, latency on the PCI bus is a big problem. If you can't get data from your HD (or RAM) to your soundcard fast enough, you _will_ hear dropouts in the audi

Actually you are quite wrong about 192 kHz being a hype. Granted if you are going back down to 44.1 you are not getting much of a benefit. But if you are say creating music for SACD or DVDA formats, it is essential. There are three problems caused by lower bit rates; greater clock jitter disto

And, that 10ms latency is added to the latency of you from the physical speakers. So you could be 6 feet away in timing instead of 3. I also bought near field monitors and I don't even use my guitar amp anymore, the difference of the shorter sound path is very noticable. Rick On Thu, 13 Jun
