Harman announced and demonstrated a new audio processing format called QuantumLogic. Extremely complex, what it offers, on both the recording and playback end, is the ability to manipulate the signal in unprecedented ways. For example, it can isolate a solo singer, or just the orchestra, or even just the ambience, and process and move it around in the sound field in almost any way the user (or the recording engineer) desires. The extraction process is nearly total. The process provides extreme flexibility for enhancing (or, it must be said, compromising) the sound, again either on recording or playback. You'll be hearing a lot more about it both here and elsewhere in the future.
The first product to include QuantumLogic will be Lexicon's new MP-20 Media Processor. It has also been implemented in a Ferrari which was on display on the show floor, but that's hardly a mass market item (nor is the five-figure processor!).
