Definition
A device that compresses audio signals before transmission and expands them after reception, reducing noise and improving signal quality over long distances. This portmanteau of 'compressor' and 'expandor' was crucial in early telecommunications, squishing signals down for efficient transmission then puffing them back up on the other end. It's audio engineering's version of vacuum-packing your voice for shipping.
Example Usage
The old telephone system used compandor technology to maintain call quality across miles of copper wire, which is why your grandmother's landline sounded better than your spotty Zoom connection.
