omnisonix, omnisonic imager is the original 3d sound in which bob carver came up with his own version, it was around 1979, and sonic holography in 1980. Whether you know it or not, many sound processors of today used by pro gear and on tv, home theater manufacturers use a form of sonic holography in the form of BBE, BEHRINGER, PEAVEY KOSMOS, DBX, aphex and the more known SRSLABS with their WOW surround. It's basically simulated surround. Several years ago, acoustic research came out with the TDS 202 spatial enhancer. In the early 90's hughes came up with their version. Some people like their music FLAT and unprocessed, people like myself who like to expand their sound, use sound processors to enhance the dynamics and soundstage of our system. It's not everyone, just like pure audio is not for everyone. Not everyone is going to enjoy tubes or stereo only or unprocessed. Even in the 80's with the dbx expanders, not everyone was into processing or expanding their tape decks or turntables. From my over 33 yrs of experience of using sound processors and being in audio, sound processors such as equalizers, reverbs, digital delay, omnisonic imagery, dbx range expanders, and sonic holography have always brought out signals in the recording I normally don't hear listening to a regular flat unprocessed amplified sound from whatever source be it a turntable or a cd player. People think that using unprocessed amplification from a source is the natural way, maybe if it was a live performance, but even with a live performance or a recording, engineers and musicians always use sound processors in the mix and therefore it is never really UNPROCESSED, that is why people is not natural aren't really making any sense to me unless the recording is that of a single instrument musician such as a solo guitar performance which would be an exemption to the rule, where as most band or group recorded music has sound processing in the mix therefor NOT SO NATURAL!
