1983: Oscar Bonello
One of the First Practical Data Compression Systems
Started with “the psychoacoustic principle of the masking of critical bands first published by the German acoustics scientist Eberhard Zwicker in 1967 in his Das Ohr als Nachrichtenempfänger. (The Ear as Message Receiver)”
Created first software/hardware on IBM-PC in 1983 (Audicom) then software-only.
“Bonello’s compression system is used in all the lossy audio bit compression systems, including MP3″
