IEEE Workshop on Speech coding Proceedings
作者: L. Tancerel S. Ragot V.T. Ruoppila R. Lefebvre Department of Electrical Engineering University of Sherbrooke Sherbrooke QUE Canada
We propose in this paper a general solution for combined speech and audio coding. Particularly, we describe a speech/music discrimination procedure for multi-mode wideband coding. The speech/music decision is updated ... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: S. Boland M. Deriche Signal Processing Research Centre School of Electrical and Electronic Systems Engineering Queensland University of Technology Brisbane QLD Australia
In this paper, we propose a new combined harmonic-wavelet representation for audio where a harmonic analysis-synthesis scheme is used, first, to approximate each audio frame as a sum of several sinusoids. Then, the di... 详细信息
