Emmy Award IEEE Jack S. Kilby Signal Processing Medal Thomas Greenway Stockham (December 22, 1933 – January 6, 2004) was an American scientist who developed one of the first practical digital audio recording systems, and pioneered techniques for digital audio recording and processing.

While at MIT, he noticed several of the students using an MIT Lincoln Laboratory TX-0 mainframe computer installed at the campus to record their voices digitally into the computer's memory, using a microphone connected to an analog-to-digital converter and a loudspeaker connected to a digital-to-analog converter, both attached to the TX-0, running the Expensive Tape Recorder application that fellow MIT students David Gross and Alan Kotok wrote for the TX-0 from 1959 to 1962.

Soundstream Inc. was the first commercial digital recording company in the United States, located in Salt Lake City.

Stockham played a key role in the digital restoration of Enrico Caruso recordings, described in a 1975 IEEE paper.

Stockham's team reached agreement on seven conclusions detailed in their 87-page report to Chief Judge John J. Sirica: 1.

The continually lowering price of compact discs led to DAT being used only in certain roles, and its last major manufacturer, Sony, phased out development starting in 2005.
