I want to know how I can perform spectral subtraction of a speech signal in order to denoise it.Pls tell me about the process and steps involved
Thanx,
Madhumitha.

Hi Madhumitha, this topic has been discussed in the newsgroup--For example:

http://www.mathworks.com/matlabcentral/newsreader/view_thread/245548#631954

Also, search the file exchange with "spectral subtraction" and you will find user-contributed Matlab code.

Hope that helps,
Wayne

Yes u can do Noise reduction using Specrtal Subtraction ..but this is
not useful for most of the noises....i done it in my project....
