Clark of AT&T in 1928 (filed in 1925): In 1942, Clark and his team completed the SIGSALY secure voice transmission system that included the first use of companding in a PCM (digital) system. In 1953, B.

Smith showed that a nonlinear DAC could be complemented by the inverse nonlinearity in a successive-approximation ADC configuration, simplifying the design of digital companding systems. In 1970, H.
Kaneko developed the uniform description of segment (piecewise linear) companding laws that had by then been adopted in digital telephony. In the 1980s (and '90s), many of the music equipment manufacturers (Roland, Yamaha, Korg) used companding when compressing the library waveform data in their digital synthesizers.
