https://www.electronics-tutorial.net/Mini-Projects/COMPANDER/
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 …

Noise Reduction with Companders – Electric Druid
https://electricdruid.net/noise-reduction-with-companders/
“Compander” is a compound of “Compressor” and “Expander”, since those are the two parts of that process. The compressor is the part that makes quiet signals louder (“compresses the dynamic range” in the jargon) and then the expander reverses the process and makes them quiet again (expands the dynamic range).
