Signal processing technique which uses both compression and expansion to improve dynamic range and signal-to-noise ratio. A signal is passed through a non-linear transformation prior to transmission. A reverse of this transformation occurs at reception. The transformation is such that quiet portions are boosted and loud portions reduced. Noise is r [..]

Refers to a device that compresses an input signal and expands the output signal in order to reduce noise. (Sound)

Outboard sound equipment. Combination of a Compressor and an Expander.

1) A two section device that is used in noise reduction systems. The first section compresses the audio signal, before it is recorded, and the second section, expands the signal after recording. 2) In [..]

An acronym for COMpressor-exPANDER. A circuit that compresses and then expands the signal in amplitude. Normally a circuit compresses the signal [level] at one end of an interface than expanding the s [..]

Any device used for companding.
