This paper describes the design of a real-time MP4 Structured Audio codec for monophonic signals. The coding of the live input consists of a pitch detection system which returns the MIDI-like data, and an additive synthesis scheme which creates and modifies the current instrument. Both parts are designed to be fast and scalable : the analysis parameters let the user choose the computational cost for both the analysis and the resynthesis. The extracted objects can then be used in live environments for encoding and/or creation.
