A Hybrid Time-Frequency Domain approach to Audio time-scale modification.
Dorran, David; Lawlor, Bob; Coyle, Eugene
Frequency-domain approaches to audio time-scale modification introduce a reverberant/phasy artefact into the time-scaled output. Such artefacts are generally not present within time-domain implementations; however, high quality time-scaling in the time domain is typically limited to quasi-periodic signals such as speech. A hybrid method of time-scaling is presented which draws upon appealing aspects of both time-domain and frequency domain implementations. The technique described can be successfully applied to a wide range of audio and is both robust and efficient. Subjective testing demonstrates that the technique significantly reduces the presence of phasiness.
