Abstract (en)
The apparatus is designed for distorting, on selections operated by the musicians, an audio signal such as that generated by an electronic musical instrument, and permits such distortion to be achieved, particularly in an automatic mode, without any substantial change in the volume, base content or treble content of the audio output. The apparatus comprises means (18, 20, 22, 24) for distorting the audio signal by a controlled degree. The distortion causes variations in the volume of the output as the degree of distortion increases and also causes increases in the bass and treble content of the output with increasing distortion. The volume variation is compensated for by providing means for automatically maintaining the volume of the audio signal outputted from the distortion element substantially uniform regardless of the degree of distortion, the compensation occuring solely as a function of the selected degree of distortion. The circuit may comprise a compressor prior to distortion. Adjustable filtering may also be applied at the input to the distortion element. <IMAGE>
