I've never had a chance to use one of these things, so i'm not sure what the effect actually sounds like. i do have an Aphex Aural Exciter (Type C) and think i understand it's principles of operation. (synthesizing harmonics) But from what i've read, spatial enhancers split up the signal into bands and delay them differently to 'enhance' the signal. This almost sounds like something that could be tried at home with a DAW, some HP,BP,LP filters and delays. (while we're at it, we could make a multi-band compressor too). Would this work? For an enhancer, does anyone know what kinds of values we'd be working with? (e.g. delay <100hz, 10ms; 100-250hz, 5 ms; >250hz, 0 ms) Is there anything proprietary going on here, or is it just a lot of work getting the values that sound right. Why would delaying the lower frequencies enhance the sound? Any takers? C.
