Elimination of Relative Spectral Energy Distortion in Electronic Compressors
The exaggeration of sibilant speech-sounds produced when electronic volume compression is employed in sound-recording channels is shown to be a form of amplitude-selective frequency distortion, which is generated by virtue of the normal mode of operation of the compressor. The practical elimination of this form of distortion is accomplished by equalization of the compressor control-rectifier input circuit, the amount of equalization employed being proportional to the inverse average relationship between rms speech-pressure per cycle and speech component frequency.
