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. We present two new phase-vocoder-based techniques which allow direct manipulation of the signal in the frequency-domain, enabling such applications as pitch-shifting, chorusing, harmonizing, partial stretching and other exotic modifications which cannot be achieved by the…

Polyphonic Pitch Modification Using Phase Vocoder Techniques

In the field of digital music processing, the phase vocoder is a well-established tool for pitch shifting and time scaling. Dolson and Laroche (1999) suggest a peak based phase vocoder, which opens…

Interpolated intermediate frames are introduced to compensate for missing signal information and have linear interpolated amplitudes and the desired characteristics could be achieved by a high quality implementation of the new method.

PITCH SHIFTING OF AUDIO SIGNALS USING THE CONSTANT-Q TRANSFORM

Pitch-scale modifications of polyphonic music are usually performed by manipulating the time-frequency representation of the input signal. Most approaches proposed in the past are thereby based on…

Estimation of Frequency for AM/FM Models Using the Phase Vocoder Framework

The robustness of the estimation against noise is studied, both theoretically and experimentally, and the performance is assessed in comparison with two state-of-the-art algorithms: an unmodified version of the reassignment method and a quadratically interpolated fast Fourier transform method.

Phase Vocoder For Time Stretch Based On Center Frequency Estimation

The proposed phase correction algorithm uses peak phase-locking and a method to find an appropriate dominant peak frequency, and it requires only a single sized FFT and has the advantage that it can be easily applied to various applications thanks to its structural similarity to the classical phase vocoder.

This paper describes the design of a practical, real-time pitch quantization system intended for digital musical effects signal processing, and employs tools such as an octave resolver and range limiter, grain boundary expansion and contraction, and transient detection to enhance the performance of the system.

A comparative evaluation of pitch modification techniques

Despite its higher compression level, the Deterministic plus Stochastic Model of the residual signal technique is shown to give similar or better results than other methods, especially for male speakers and important ratios of modification.

Improved phase vocoder time-scale modification of audio

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.

An improved formulation of the phase vocoder is proposed for which the first difficulty does not arise; and a means of phase-locking adjacent channels of the resynthesis is proposed which alleviates the second one.

Variable-frequency synthesis: An improved harmonic coding scheme

Harmonic Coding is synthesized in the time domain, as a superimposition of "harmonics" whose instantaneous frequency varies continuously along an interpolation curve, within each frame, so that fast pitch variations can be tracked with no difficulty.

A unified approach to short-time Fourier analysis and synthesis

The effects of modifications made to the short-time transform are explicitly shown on the resulting signal and it is shown that a formal duality exists between the two synthesis methods based on the properties of the window used for obtaining theshort-time Fourier transform.

Speech analysis/Synthesis based on a sinusoidal representation

A sinusoidal model for the speech waveform is used to develop a new analysis/synthesis technique that is characterized by the amplitudes, frequencies, and phases of the component sine waves, which forms the basis for new approaches to the problems of speech transformations including time-scale and pitch-scale modification, and midrate speech coding.
