An Entropy Based Method for Local Time-Adaptation of the Spectrogram

Autor: Liuni, M., Röbel, A., Romito, M., Rodet, X.

Publikováno v: CMMR 2010, LNCS 6684, pp. 60-75, 2011

We propose a method for automatic local time-adaptation of the spectrogram of audio signals: it is based on the decomposition of a signal within a Gabor multi-frame through the STFT operator. The sparsity of the analysis in every individual frame of

A Reduced Multiple Gabor Frame for Local Time Adaptation of the Spectrogram

Autor: Liuni, M., Röbel, A., Romito, M., Rodet, X.

Publikováno v: Proc. of the 13th Int. Conference on Digital Audio Effects (DAFx-10), Graz, Austria , September 6-10, 2010

In this paper we propose a method for automatic local time adap- tation of the spectrogram of an audio signal, based on its decomposition within a Gabor multi-frame. The sparsity of the analyses within each individual frame is evaluated through the R
