Previous: Digital Audio and MIDI
- We have seen the need for compression already in Digital Audio -- Large Data Files
- Basic Ideas of compression (see next Chapter) used as integral part of audio
format -- MP3, real audio etc.
- Mpeg-4 audio -- actually combines compression synthesis and midi to have a
massive impact on compression.
- Midi, Synthesis encode what note to play and how to play it with a small number
of parameters -- Much greater reduction than simply having some encoded bits of audio.
- Responsibility to create audio delegated to generation side.
