Time Scale Modification of Audio Using Non-Negative Matrix Factorization

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

This paper introduces an algorithm for time-scale modification of audio signals based on using non-negative matrix factorization. The activation signals attributed to the detected components are used for identifying sound events. The segmentation of these events is used for detecting and preserving transients. In addition, the algorithm introduces the possibility of preserving the envelopes of overlapping sound events while globally modifying the duration of an audio clip.
