What exactly are NoNOISE and CEDAR? How are they used?
NoNOISE and CEDAR are systems for noise removal. Both of them approach the same sorts of noise, but use different algorithms and have different user interfaces, often with differing effectiveness. Noise can be broken down into several categories: IMPULSIVE NOISE: Pops, clicks, thumps, snaps. CRACKLE: The low-level “bacon frying” effect heard on LP’s and 78’s. HISS: Tape hiss, surface noise, amplifier hiss, broadband noise BUZZ: 60 Hz hum, any other steady-state noise that is relatively narrow-band NoNOISE and CEDAR are two (expensive) techniques for removing many of these ailments. It is rare that it is possible to remove all of the problem, nor is it ever possible to remove it with no degradation of the program material.
