Phase reconstruction of spectrograms with linear unwrapping: application to audio signal restoration
Paul Magron, Roland Badeau, Bertrand David
This paper introduces a novel technique for reconstructing the phase of modified spectrograms of audio signals. From the analysis of mixtures of sinusoids we obtain relationships b…
