Real-time detection of musical onsets with linear prediction and sinusoidal modeling
John Glover, Victor Lazzarini, Joseph Timoney · EURASIP Journal on Advances in Signal Processing · 2011
Real-time musical note onset detection plays a vital role in many audio analysis processes, such as score following, beat detection and various sound synthesis by analysis methods. This article provides a review of some of the most commonly used techniques for real-time onset detection. We suggest ways to improve these techniques by incorporating linear prediction as well as presenting a novel algorithm for real-time onset detection using sinusoidal modelling. We provide comprehensive results for both the detection accuracy and the computational performance of all of the described techniques, evaluated using Modal , our new open source library for musical onset detection, which comes with a free database of samples with hand-labelled note onsets.
