Summary on Grant Application Form |
|
Current coding systems for musical audio tend to use transform coding or filterbanks, with bit allocation determined by psychophysical masking thresholds. A recent alternative approach is to decompose the signal Into a parametric encoding, consisting for example of sinusoids+noise or tonals+transients+residuals. In this project, we will develop a methodology for audio coding using higher-level sound objects , consisting of Individual notes or chords played by particular instruments. From a top-down direction, this will be based on our expertise on automatic music transcription. We will explore a range of alternative approaches using different levels of Information, down to sparse coding methods for grouping of low-level parametric coding objects. We will Initially investigate coding of simple monophonic (single-voice) musical audio, extending this work to single-instrument and smallgroup polyphonic musical audio as the project progresses. We will use MPEG-4 Structured Audio as our primary encoding format. While full objectbased coding of complex polyphonic audio scenes (such as a symphony orchestra) is still a long way off, this project is a first step towards this Important long-term goal.
