- Brossier, J. P. Bello and M. D. Plumbley. Real-time temporal segmentation of note objects in music signals, in Proceedings of the International Computer Music Conference (ICMC 2004), Miami, Florida, USA, November 1-6, 2004.
Abstract: Segmenting note objects in a real time context is useful for live performances, audio broadcasting, or object-based coding. This temporal segmentation relies upon the correct detection of onsets and offsets of musical notes, an area of much research over recent years. However the low-latency requirements of real-time systems impose new, tight constraints on this process. In this paper, we present a system for the seg- mentation of note objects with very short delays, using recent developments in onset detection, specially modified to work in a real-time context. A portable and open C implementation is presented.

Abstract: We present a new system for the estimation of note attributes from a live monophonic music source, within a short time delay and without any previous knowledge of the signal. The labelling is based on the temporal segmentation and the successive estimation of the fundamental frequency of the current note object. The setup, implemented around a small C library, is directed at the robust note segmentation of a variety of audio signals. A system for evaluation of performances is also presented. The further extension to polyphonic signals is considered, as well as design concerns such as portability and integration in other software environments.
