Description: White noise is a random signal (or process) with a flat power spectral density. In other words, the signal contains equal power within a fixed bandwidth at any center frequency. White noise draws its name from white light in which the power spectral density of the light is distributed over the visible band in such a way that the eye s three color receptors (cones) are rather equally stimulated, so the white Gaussian noise the values that the noise can take on are Gaussian-distributed.-This file includes matlab source and explanation report Platform: |

Description: Based on the spectrum of the vuvuzela sound, this denoising technique simply computes an antenuation map in the time-frequency domain. Then, the audio signal is restored by computing the inverse STFT. See [1] or [2] for more detail about the algorithm.
