Early 1970s:
Prof. Dieter Seitzer of Erlangen-Nuremberg
University in Germany begins
wrestling with the problem of compressing music over phone lines. Initially
refused research money to pursue the goal, he establishes a group of
technicians and scientists interested in audio coding research to tackle the
problem
1979: Prof.
Seitzer's team develops a first digital signal processor capable of audio
compression. During subsequent development, a student of Prof. Seitzer,
Karlheinz Brandenburg,
developed and enhanced basic principles for perceptual audio coding exploiting
the hearing properties of the human ear as described in psychoacoustics. Under
Seitzer's guidance, Brandenburg
and the team continuously developed a number of coding algorithms.
