N2 - Frequency-domain approaches to audio time-scale modification introduce a reverberant artifact into the time-scaled output due to a loss in phase coherence between subband components. Whilst techniques have been developed which reduce the presence of this artifact, it remains a source of difficulty. A method of time-scaling is presented that reduces the presence of reverberation by taking advantage of some flexibility that exists in the choice of phase required so as to maintain horizontal phase coherence along frequency-domain subband components. The approach makes use of appealing aspects of existing time-domain and frequency-domain time-scaling techniques.
