his is a simple method for silence removal and segmentation of audio streams that contain speech. The method is based in two simple audio features (signal energy and spectral centroid). As long as the feature sequences are extracted, as thresholding approach is applied on those sequence, in order to detect the speech segment

用于消噪处理用于研究Mallet算法及滤波器设计分解的高频系数采用db9较好,即它的消失矩较大(for Signal Processing Algorithms for the study Mallet decomposition and filter design using high-frequency coefficients db9 better, that is, its larger vanishing moments)

This code is only intended to explain the basics behind the bandelet transform, and to be able to play with the major concepts and properties of these orthogonal basis. It does not contain any coding scheme, nor a fast implementation(This code is only intended to explain the basics behind the bandelet transform, and to be able to play with the major concepts and properties of these orthogonal basis.
