Wavelets Based Denoising

25 Nov 2004 (Updated 29 Nov 2004)

This program shows wavelets based denoising of audio file and arbitrary signals.

File Information
Description	This program demonstrate abilty of wavelets to denoise audio data as well its effectiveness on different type of signals at different SNR. I have tested this program on windows xp and MATLAB 6.1 it works perfectly
Required Products	DSP System Toolbox
MATLAB release	MATLAB 6.1 (R12.1)
Other requirements	Windows, Matlab 6.1
