Product literature - Dynamic Noise Filter Model 1000 - March 1974.pdf How it works -A Dynamic noise Filter for Mastering - Audio June 1972.pdf Burwen Laboratories Noise Eliminator Model 2000 - 1970s This was Dick's toughest engineering challenge - a 3:1 companding noise reduction system that added 50 dB dynamic range to an analog tape recorder. It did not quite sell to A & M Records who loved the performance, but decided not to try to lead the recording industry to a new recording standard instead of Dolby. Dick made many live classical concert and studio recordings via the Noise Eliminator before digital tape became available. Unfortunately the oxide on analog tapes of that era deteriorated. A few years ago Dick threw out a roomful of these wide dynamic range tapes because he did not want to spend the rest of his life baking tapes to restore them.
