Intel P4 3.4Ghz
I'm having a problem with PristineSpaceLight and I'm not sure what's causing it. When I have a sequencer project loaded, I usually hear nothing in the headphones at all when the sequencer is stopped (as one would hope!). Anyway, the sequencers (either Tracktion or energyXT, happens in both) run in End-To-End mode, so the effects are still being processed and sent to audio when the sequencer is stopped.
When I added an instance of PSLight, things are fine. When I add an Impulse Response to PSLight, I get a noticeable (but quiet) crackling sound. If I disable PSLight, the sound goes away. If I remove the WAV, the sound goes away.
I've tried using different impulses (mostly from noisevault, some from voxengo) and I get the same rustling sound (though the rustle noise varies depending on the WAV used). I've also tried using different latencies.
I haven't noticed this on either another workstation (with the same Impulse Responses in PSLight) or on my laptop. So I'm not sure what's causing it.
I wondered if it might be something to do with the Intel processor? Hyperthreading etc?
I been doing some more testing. It seems that Hyperthreading is already disabled in the BIOS. I've also tried expanding the latency on the audiocard, but it doesn't seem to make a difference.
I'm certain that it's some kind of motherboard/system inteference of the graphics card and the on-board audio chip.
For instance, when I drag the sequencer gui, or a window in Photoshop, I hear noise in the headphones consistent with graphics card inteference, so I think I should probably invest in a decent PCI audio card for this machine.
