ICASSP 2025accepted

Ultrasonic vocalizations (USV) convey information about individual identity and arousal status in mice. We propose to track USV as ridges in the time–frequency domain via a variant of time– frequency reassignment (TFR). The key idea is to perform TFR with empirical Wiener shrinkage and multitapering…

Adversarial Generation of Time-Frequency Features with application in audio synthesis

Andrés Marafioti, Nathanaël Perraudin, Nicki Holighaus, Piotr Majdak

ICML 2019oral

Time-frequency (TF) representations provide powerful and intuitive features for the analysis of time series such as audio. But still, generative modeling of audio in the TF domain is a subtle matter. Consequently, neural audio synthesis widely relies on directly modeling the waveform and previous at…
