So, I have this MP3, it was recorded from a vynil and this ****cker (yeah the guy who recorded) hasnt cared about his wiring, so we have this terrible hum, it OK on louder parts cuz MP3 coding hides that, we dont hear it, but on less loud parts its terrible.

The problem is that this hum is somewhat too broad, smthg like 50-150hz constatnt level, event viewing using 65k FFT window size.

Notching 50 or 60 hz and odd harmonics did help alot, if I select smaller Q on paramteric, hum dissapeares, so as the bass :xeye:

But 1 thing is for sure - it must be a ground loop hum, i.e. 50 or 60 hz whatsoever, dont looks like 50 hz coz here it hums "different" :D

Any ideas ? (despite of looking for other file)
