Jonathan Manton, sound archive librarian at the Stanford University Libraries, has just published this article and mp3 file: on September 2nd, 2015, he carried out an oral history interview with John Chowning, Professor Emeritus at Stanford’s Center for Computer Research in Music and Acoustics (CCRMA) and inventor of Frequency Modulation (FM) synthesis.
They discussed Chowning’s background in computer music, his history at Stanford and the inception of CCRMA, his collaboration with Max Mathews.
But, most importantly, they discussed Leon Theremin’s visit to Stanford in 1991, which Chowning organized and oversaw.
