This is another free dynamic EQ recommended by others on the site. I have used it and it is cool.

I have used it to successfully reduce 60 cycle hum to an almost inaudible level.

The "Q" setting on this will allow you to focus in on a very narrow frequency.

Try to find the frequency where it is squeaking and see if you can squash it out.

If you can, share you settings and let the rest of us know!

Otherwise, you may have to go into audacity and do a lot of time consuming squeak removal, if you don't use Mario's tricks.
