IEEE Workshop on Applications of Signal Processing to Audio and Acoustics
作者: Bharitkar, S Kyriakakis, C Univ So Calif Integrated Media Syst Ctr Los Angeles CA 90089 USA
Typically, room equalization techniques do not focus on designing filters that equalize the room responses at perceptually relevant frequencies. Thus, by performing Bark warping of the room responses and using lower o... 详细信息

32nd IEEE International Conference on Acoustics, Speech and Signal Processing
作者: Holters, Martin Pabst, Oliver Zoelzer, Udo Helmut Schmidt Univ Univ Fed Armed Forces Dept Signal Proc & Commun Hamburg Germany
We propose an extension of ADPCM that includes adaptive pre- and post-filtering to achieve spectral shaping of the coding noise. The advantage of this coding scheme is that it allows a realization without algorithmic ... 详细信息
