Ad Lib, Inc. was a Canadian manufacturer of sound cards and other computer equipment founded by Martin Prevel, a former professor of music and vice-dean of the music department at the Université Laval.[1] The company's best known product, the AdLib Music Synthesizer Card (ALMSC), or simply the AdLib as it was called, was the first add-on sound card for IBM compatibles to achieve widespread acceptance, becoming the first de facto standard for audio reproduction.[2]
