Drum Event Detection by Noise Subspace Projection and Classification

Abstract

Pre-processing of stereo signals A pair of gains is selected for each channel, in order to maximize an impulsiveness criterion on the envelope of the remixed monophonic signal. The impulsiveness measure I is computed as follows: Firstly, an envelope signal s′(t) is obtained by half-wave rectifying, decimating, low-pass filtering, and differentiating s(t… (More)
