how to improve voice record quality?

[birang]

hello
my friend has been recorded some classes under the .mp3 format in low level quality and there are so much echos and noises on the files
i need to somehow improve the teachers' voice and reduce those echos and noises from the files
can you guys recommend me some program to do that job?
thanks in advance!

Hi Birang - to be honest, once there is reverb/echo on the files, you won't really be able to remove it as such - you might be able to remove some of the underlying noise using any one of a number of audio programs.

A free program to try would be Audacity - http://audacity.sourceforge.net/

Hope this helps.

Cheers.
