Freeware Program To Eliminate Hum From Wav Files?

[kelticwizard]

I recorded from a cassette to the computer, turning all the individual songs into wav files. This is on a friend's computer.

We have done this before, with success.

This CD we burned from those wav files, however, had a hum on all the songs. When we play the original cassette, there is no hum.

I should point out that his cassette and amp are located about 10 feet or so from the computer. I have never appreciated that long a run from his preamp output to his soundcard, but it never seemed to much of a problem before.

I was wondering if there is a freeware program that eliminates all 60 Hz or 120 Hz tones from a wav files without going through the effort of playing the wav file in "real time".

If there is no such program, does anyone know of a freeware equalizer program that has a slider set for both 60 Hz and 120 Hz exactly?

What I am trying to do is to eliminate the two tones that hum normally takes place while affecting other frequencies as little as possible.l

Thank you for any help or advice you can give me on this issue.

Its a long time ago I used those progs, they are really great,
I think Cooledit 2000 could do the trick.
You can download a limited version, but if memory serves, there are enough filters to get rid of your hum.
Personally, I would try to make a new, better recording of the original files. Always better than cleaning up things.

You could also use goldwave it is similar to cool edit but less powerful.

Make 2% wide notches at 60Hz, 120Hz, 180, 240, 300 etc to 540Hz. Makes a big difference. CoolEdit '96 can be found here and there and the demo version has enough functionality to do this and way more.

"Samplitude Producer" is a fully fledged recording and editing suite.
It has as narrow as you like it FFT filters to home in on and notch any frequency you like.
