Here are some comments about Coherence Technology's approach to music noise reduction: 

“This is my own album, and I’ve heard things I’ve never heard before. This is great!” --M. W., Leader and musician for a Rhythm and blues group

“Copies made on high bias tape were crystal clear with excellent high end reproduction during playback without dolby!” --N. A. A., Producer/Arranger/Songwriter

“By way of analogy, imagine listening to a selection of music with some cotton in your ears and notice the difference when you take out the cotton...suffice to say, I was impressed.”   --S.H., Producer, Recording Artist

“You’ve taken the final objection out of Digital Recordings and CD’s.” --P. B., Executive producer of a leading entertainment production company

“There was greater clarity, distinction, definition in the entire range and band width. There was more spatial depth. Front and back imaging was better. The sound carried farther at lower levels. The piece without your technology sounded tight and restricted; with your technology it was much more full. Much more emotion came through.” --M. S., Musician and Sound Engineer

“The thing that I perceive that is unique in evaluating your technology is the immediate sense of subjective enjoyment.” --J. H., V.P., a manufacturer of Audio Systems


“The music had a freer feeling as if a pressure had been lifted. The sounds were not restricted but moved around with ease. It had a more relaxing effect on my physiology, and, hearing (the version with Coherence Technology’s Quantum Noise Reduction System™ (QNRS™) made me realize that the regular (store bought) version felt full of stress and strain. In general the music sounds happier.” --T. S., Writer for an audio magazine
