This audio compander circuit schematic is equiped with NE575 produced by Signetics, it is working with a 3 – 7V battery and has a current consumption of 3.5mA at 3V and 5mA at 7V. The companding process ( input compression, output as expander) is improving the signal/noise ratio on a communication line.

Audio compressor is much used in disk or tape recording, and can be interposed between the output of a mixer and the input of a tape recorder in order to ensure that the maximum recording level is not greatly exceeded. The unit can be used as the volume control between the pre-amplifier and the power amplifier in an audio system.

A Compander is a non-linear circuit which provides high amplification for low input amplitude signals and low amplification for high input amplitude signals. A compander operates in a transmitter to compress audio signals before they are transmitted and in a receiver to expand the audio signals after they are received.
