The name is a portmanteau of compressing and expanding. While the compression used in audio recording and the like depends on a variable-gain amplifier, and so is a locally linear process (linear for short regions, but not globally), companding is non-linear and takes place in the same way at all points in time. The dynamic range of a signal is compressed before transmission and is expanded to the original value at the receiver. The electronic circuit that does this is called a compandor and works by compressing or expanding the dynamic range of an analog electronic signal such as sound. One variety is a triplet of amplifiers: a logarithmic amplifier, followed by a variable-gain linear amplifier and an exponential amplifier. Such a triplet has the property that its output voltage is proportional to the input voltage raised to an adjustable power. Compandors are used in concert audio systems and in some noise reduction schemes such as dbx and Dolby NR (all versions). Companding can also refer to the use of compression, where gain is decreased when levels rise above a certain threshold, and its complement, expansion, where gain is also decreased when levels drop below a certain threshold. Companding is used in professional wireless microphones to improve the dynamic range of the microphone (the dynamic range of the microphone itself is higher than the dynamic range of the radio transmission). The use of companding allows signals with a large dynamic range to be transmitted over facilities that have a smaller dynamic range capability. Companding reduces the noise and crosstalk levels at the receiver. Companding is used in digital and telephony systems, compressing before input to an analog-to-digital converter, and then expanding after a digital-to-analog converter. This is equivalent to using a non-linear ADC as in a T-carrier telephone system that implements A-law or \u03BC-law companding. This method is also used in digital file formats for better signal-to-noise ratio (SNR) at lower bit rates. For example, a linearly encoded 16-bit PCM signal can be converted to an 8-bit WAV or AU file while maintaining a decent SNR by compressing before the transition to 8-bit and expanding after a conversion back to 16-bit. This is effectively a form of lossy audio data compression."@en , "Compans\u00E3o \u00E9 uma t\u00E9cnica de compress\u00E3o e expans\u00E3o de sinais para efeitos de redu\u00E7\u00E3o de ru\u00EDdos e quantiza\u00E7\u00E3o."@pt , "Kompandor to urz\u0105dzenie do zmiany dynamiki transmisji, stanowi\u0105ce zesp\u00F3\u0142 sk\u0142adaj\u0105cy si\u0119 z kompresora umieszczonego na pocz\u0105tku toru i ekspandora umieszczonego na ko\u0144cu toru."@pl ; rdfs:comment "In telecommunication, signal processing, and thermodynamics, companding (occasionally called compansion) is a method of mitigating the detrimental effects of a channel with limited dynamic range.
