Anyone have any experience with these, or know what the best case output snr is ? If it can take a signal with noise at about -70db, and lower that to -96db it would cover a multitude of sins...
This approach sounds very much like the old DNR noise reducers - a VCLP
filter, which I've used quite a bit. On material with bass content,
it's much less obtrusive than companders, but still does nasty things to
solo triangles. IMHO, there's still no 'magic' noise reducer. As a
coincidence, I just bought one of the Ensoniq cards this week - I'll be
interested to see how it performs in the real-life PC 'jungle'!
