Fast labelling of notes in music signals

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.
