Multi-channel Audio Time-scale Modification
Document Type Conference Paper
Audio Engineering Society Convention Paper presented at the 119th. Convention October 7-10, 2005, New York.
Phase vecoder based approaches to audio time-scale modification introduce a reverberant artefact into the time scaled output. Recent techniques have been developed to reduce the presence of this artefact; however, these techniques have the effect of introducing additional issues relating to their application to multi-channel recordings. This paper addresses these issues by collectively analysing all channels prior to time-scaling each individual channel.
