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.
To hear the result of this algorithm, go directly to: http://soundcloud.com/choc29/vuvuzela-correction-with-matlab

Description: Wavelet Toolware is a companion software package to the book An
Introduction to Wavelets by Charles K. Chui. It is designed for the
reader to gain some hands-on practice in the subject of wavelets. The
objective is to provide basic signal analysis and synthesis tools that are
flexible enough for the reader to easily increase the capability of the
Toolware by adding processing algorithms to tailor to specific areas of
application. Wavelet Toolware contains, among other algorithms and
codes, the one-dimensional (1-D) and two-dimensional (2-D) Discrete
Wavelet Transforms (DWTs) and their inverse transforms, as well as
computations of the Continuous Wavelet Transform (CWT) and the
Short Time Fourier Transform (STFT).-Wavelet Toolware is a companion software package to the book An
