Abstract

An onset detection system that exploits MPEG-7 audio descriptors is proposed in this paper, with investigations into the feasibility of MPEG-7 based onset detection performed across a diverse database of music. Detection functions were developed from both individual MPEG-7 descriptors and combinations of descriptors (joint detection functions). The results indicated that individual descriptors could achieve respectable detection performance (maximum F-measure of 0.753) with basic waveform features. Average detection performance could be improved by up to 11.2%, however, when joint detection functions were comprised of diverse combinations of MPEG-7 descriptors. This may be attributed to the increased capability of detection functions, composed of different spectral and temporal features, in capturing the variation in onset characteristics from different musical styles. It is thus concluded that the proposed onset detection system could be plausibly integrated into an existing MPEG-7 audio analysis system with minimal computational overhead.
