Improving Phase-Vocoder-Based Time Stretching by Time-Directional Spectrogram Squeezing

ICASSP 2023accepted

Time stretching of music signals has a crucial problem, i.e., smearing of percussive sounds. Some time stretching algorithms have addressed this problem by detecting percussive components and manipulating them differently from the other components. However, conventional methods cause artifacts. In t…

Harmonic and Percussive Sound Separation Based on Mixed Partial Derivative of Phase Spectrogram

ICASSP 2022accepted

Harmonic and percussive sound separation (HPSS) is a widely applied pre-processing tool that extracts distinct (harmonic and percussive) components of a signal. In the previous methods, HPSS has been performed based on the structural properties of magnitude (or power) spectrograms. However, such app…
