Yes of course and actually it's not a good idea, I was trying it and it coloured my reverb.Well, if you sum it back to 1D (or throw away one of the components) then it's no longer spectrally white.
However I'm now feeding either a FDN or the figure 8 loop by this feed forward diffuser (but not mixing the output of the diffuser then) and I get a cool true stereo reverb with a shapable attack, that's super cool !
Now I'm trying to see how I can smartly control the channel cross feeding, if ever it can enhance the stereo.
Thanks for sharingThat sounds like Miller Puckette to me: http://msp.ucsd.edu/techniques/v0.11/bo ... de111.html
If the CPU doesn't matter, then the fdn with 32 delaylines would be the late reverb component, better than the figure eight, the fdn produces a really dense noise, totally colorless.The filters (typically one-poles) should be free on modern CPUs. The CPU cost boils down to the memory accesses and how well you take advantage of the cache. Whatever you do though, anything that has a core of say 6-16 delays (not counting diffusion) should be totally fine, CPU-wise. You could even use a lot more, but I doubt it will help perceptually.
