I am attaching a sample sound noise. It is a lecture. The noise comes from the electric contact. Can anyone help figure out a way to remove the noise using Audacity. I installed the latest version 2.0.5 on window 7. Thanks a lot!
“Effect > Equalization” and use the “Telephone” preset. That will probably stop the noise from hurting your ears, but not much more than that. That’s probably as good as it gets. The damage is really beyond repair.
Thanks! Steven. It is getting better but not as good. See attached new sample. Is there any more complicated way to make the voice more better? Thanks!
