noise removal in Matlab

Hi,

I'm currently having trouble removing noise from my recorded signal with
Matlab. The recording is a piece of live guitar performance recorded at a
restaurant environment.

I'm wondering if anyone of you can give me a hand on how to design a noise
removal tool in Matlab? Your advice and help will be highly appreciated!!

Regards,
Ada

Hi Wang King,

Thanks for the tip! I've already tried using some audio editing package
like audacity to remove the noise. But the result is not satisfactory at
all. That's why I wanna give it a try with Matlab. 

^_~ thanks a whole bunch though!

What precisely is your noise ?
Is it white noise or "background signal" (e.g. talks of people) ?
If your noise is actually "background signal", then you need source
seperation
package to do that.
A possible way is to use ICA.
You can search in google for the matlab code.
Some codes could be helpful here:

Hi! Thanks for the link! My noise is the so-called "background signal".
Since my recording was taken in a noisy environment, I had lots of people
talking/walking in the background.
