During CES 2010 Tom Merrit and Rafe Needleman of CNET sat down with Karlheinz Brandenburg, co-inventor of MP3. Brandenburg is a professor at the Institute for Media Technology at Technical University of Ilmenau and also serves as director of the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau.
MP3 is short for MPEG- 1 Layer 3 and is enjoyed by millions of people daily. Audiophiles often discredit MP3 for compressing and removing audio data found in the original recording.
Interview Discussion: (video is roughly 17 min.)
- Origins of MP3 (what was it trying to solve, how was it named, file extension?)
- Reasons for success of MP3
- Problems with MP3 (pre echo issue with percussive material)
- MP3 vs. AAC (“AAC is what MP3 should have been from the beginning”)
- How MP3 works (Psychoacoustics, masking, quantization noise)

- Blind testing
- Future of MP3… MP3 Surround, MP3 metadata databases
