The circuit expander compressor furnishes both the functions-compression and expansion (often expressed by the term compander)-easily. The expander compressor uses an opto-isolator. The LED from the opto-isolator is connected to the speaker terminals via a current limiting resistor in conjunction with potentiometer VR 1 to sample the program material from …
Cost-Effective Compander Circuit V571D/M
https://www.coolaudio.com/docs/COOLAUDIO_V571_DATASHEET.pdf
Circuit Description The V571D/M compandor building blocks, as shown in the block diagram, are a full-wave rectifier, a variable gain cell, an operational amplifier and a bias system. The arrangement of these blocks in the IC result in a circuit which can perform well with few external components, yet can be adapted to many diverse applications.

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. An electronic circuit implementing the compander consists of a logarithmic amplifier at the transmitter for compression and an anti-logarithmic amplifier at the receiver to nullify the effect caused by the …

Compressor Circuit with 570/571 Compandor IC. September 5, 2011 Rust. Compressor circuit provide high gain for low amplitude input and provide low gain for high amplitude input. This action, in effect, produce a nearly constant amplitude even though the input has very high dynamic range (very high amplitude variation from time to time). The action of compression like this is …
