Enhancing time-frequency resolution with optimal transport and barycentric fusion of multiple spectrogram
David Valdivia, Elsa Cazelles, Cédric Févotte
Time-frequency representations, such as the short-time Fourier transform (STFT), are fundamental tools for analyzing non-stationary signals. However, their ability to achieve sharp…

Audio signal interpolation using optimal transportation of spectrograms
David Valdivia, Marien Renaud, Elsa Cazelles +1
We present a novel approach for generating an artificial audio signal that interpolates between given source and target sounds. Our approach relies on the computation of Wasserstei…
