[2] In 1984, Lexicon won an Emmy Award for Engineering Excellence for the Model 1200 Audio Time Compressor and Expander, widely used in the television industry.

[5] He was part of a team working on the first Digitally Controlled Milling Machine [6] In 1955, Lee joined the Bizmac Computer Division of RCA.

[7][8] In 1963, Lee accepted a one-year appointment to work on Project MAC, a time-sharing Multiple Access Computer being developed at MIT under the direction of Robert Fano.

[9] Fano launched Project MAC with a 6-week summer session that drew 57 people (including Lee) from universities, industry, and government for brainstorming and collaboration.

[11] Six years later, Lee presented "Study of Look-Aside Memory," at the IEEE (Institute of Electrical and Electronics Engineers) conference: Transactions on Computers, held in June 1969.

A digital delay device would allow heartbeats to be monitored with a continuous moving image on a cathode ray terminal (CRT).

Lee brought in Professor Stephen K. Burns, an MIT colleague with a strong interest in bio-medical electronics, to help develop the machine, patented in 1971.

At the time, sound delay technology (used to create deliberate echo effects) relied on tape loops and recording devices.

[33][34] Lexicon's Time Compressor Model 1200 received an Emmy in 1984 from the National Academy of Television Arts and Sciences for its technical contributions to editing.

[35][36] Critics argued that the Time Compressor technology, particularly when applied to movies and older television programs, amounted to "defacing" a creative work, analogous to colorization.

[3] Film director Elliot Silverstein argued that, "To use these devices before the artist completes his work makes it part of the creative process.

Stanley Kubrick, for example, used the time-compression device to speed up the sound of guns firing in Full Metal Jacket to intensify the battle scenes.

[3] American musician and producer Chris Walla used the early model, Varispeech, to create audio effects, such as making "everything sound like Dr.
