Audio signals rectified by diodes develop bias across R1 and C1 such that diodes are back-biased. Diodes thus conduct and clip only when noise signal peaks exceed bias level.Component values depend on impedance of audio circuit；table gives values for thre common load resistors. Diodes are fast-switching silicon such as 1 N 916. To minimize residual clipping distortion. use value for CF that gives 3-dB rolloff at about 2.5 kHz.-P. Lovelock. The Audio Bishop. 73 Magazine. Sept. 1974. p 75-76
