Non-parametric techniques for pitch-scale and time-scale modification of speech
Eric Moulines,Jean Laroche +1 more
TL;DR: This contribution reviews frequency-domain algorithms (phase-vocoder) and time- domain algorithms (Time-Domain Pitch-Synchronous Overlap/Add and the like) in the same framework and presents more recent variations of these schemes.
Journal ArticleDOI
Improved phase vocoder time-scale modification of audio
Jean Laroche,Mark Dolson +1 more
TL;DR: This paper examines the problem of phasiness in the context of time-scale modification and provides new insights into its causes, and two extensions to the standard phase vocoder algorithm are introduced, and the resulting sound quality is shown to be significantly improved.
Proceedings ArticleDOI
HNS: Speech modification based on a harmonic+noise model
TL;DR: HNS (harmonic plus noise synthesis), an analysis/modification/synthesis model based on a harmonic plus noise representation of the speech signal, is presented and informal listening-tests demonstrate the effectiveness of this approach for time-scale modifications.

Process for identifying audio content
TL;DR: In this paper, a fingerprint of an audio signal is generated based on the energy content in frequency subbands, which is then compared to a database to identify the audio signal, which will be useful for signals altered subsequent to the generation of the fingerprint.
Proceedings ArticleDOI
New phase-vocoder techniques for pitch-shifting, harmonizing and other exotic effects
Jean Laroche,Mark Dolson +1 more
TL;DR: The phase-vocoder is usually presented as a high-quality solution for time-scale modification of signals, pitch-scale modifications usually being implemented as a combination of timescaling and sampling rate conversion.
