Abstract
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.
