A single-ended noise suppressor designed to eliminate or reduce noises due to imperfections in and damage to sound recordings in all analog audio media and their digital reproduction, including cylinder, disk, film wire and tape recordings, both monophonic and stereophonic.
Model 325 contains three processors designed to suppress transient noises (ticks, pops, clicks, crackle, scratch) encountered in some 100 years of phonograph recordings, wherever and however made, as well as the audible hiss familiar in all audio media prior to the development of successful encode/ decode noise suppression systems and, more recently, digital audio.
