The function calculates the averaged power spectrum with proper normalization, and even if the signal is given in volts, the value is the power value. Requirements: - MATLAB 7.7 or higher Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

The two-step noise reduction (TSNR) technique removes the annoying reverberation effect while maintaining the benefits of the decision-directed approach. However, classic short-time noise reduction techniques, including TSNR, introduce harmonic distortion in the enhanced speech. To overcome this... Platforms: Matlab

This 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... Platforms: Matlab
