Just pointing out the hypocricy. When the repubs want to reform social security we are stealing from everyone, but when the dems actually are stealing from everyone they call it compansion
According to the psychoacoustics of noise reduction, the ear functions similarly as a spectrum analyzer does, effectively dividing sounds into frequency bands, called "critical bands." In order to simultaneously mask a variety of possible noises occurring in different parts of the spectrum, it is necessary to keep signal levels high at all times relative to the noise level across the entire audio spectrum.
Two elements of the dbx system are key to satisfying this constraint: wideband
compansion and spectral
compansion. The wideband
compansion keeps overall signal levels high during transmission. The spectral
compansion optimizes the spectrum that is transmitted. It acts like a sophisticated, signal-controlled treble control hinged around 1,000 Hz.
