The paper addresses the problem of modifying the playback speed of audio recordings while maintaining high signal quality and naturalness (i.e. time scaling while preserving frequency domain characteristics). An automatic time-warping method is proposed which is based on a criterion of maximal local similarity between original and time-warped waveforms. Tests on time domain and subband domain representations of audio are discussed and show the practicality of the approach taken.
