This paper presents a review on techniques for signal reconstruction without phase, ie when
only the spectrogram (the squared magnitude of the Short Time Fourier Transform) of the …

A noniterative method for the reconstruction of the short-time fourier transform (STFT) phase
from the magnitude is presented. The method is based on the direct relationship between …

Envelope representations such as the auditory or traditional spectrogram can be defined by
the set of envelopes from the outputs of a filterbank. Common envelope extraction methods …

With the recent attention to audio processing in the time-frequency domain we increasingly
encounter the problem of missing data. In this paper we present an approach that allows for …

The problem of recovering a signal from the magnitude of its short-time Fourier transform
(STFT) is a longstanding one in audio signal processing. Existing approaches rely on …

This paper describes a new algorithm that solves a particular phase retrieval problem, with
important applications in audio processing: the reconstruction of a function from its …

We discuss the problem that consists in reconstructing a function from the modulus of its
wavelet transform. In the case where the wavelets are Cauchy wavelets, all analytic …

Over the past two decades several hierarchical learning models have been developed and
applied to a diverse range of practical tasks with much success. Little is known, however, as …

A Matlab/GNU Octave toolbox for phase (signal) reconstruction from the short-time Fourier
transform (STFT) magnitude is presented. The toolbox provides an implementation of …

ABSTRACT A novel technique of unmasking to repair the degradation in sources separated
by spectrogram masking is proposed. Our approach is based on explicit knowledge of the …
