Prem's filters are not doing a very good job of taking out a background HUMMMM set up by a single, tolling church bell.

I read a thread a couple of weeks ago about a sound programme that can eliminate this by taking a sample of the 'hum' and then removing that waveband from the rest of the audio.

Someone said that he often calls for a few seconds silence while recording the drone from a motor. This enables him to take it out later on.

Oh yes, I remember reading it but I can't bloody find it!

Any pointers please....

All these programs (Cool Edit, Sound Forge, Vegas etc) will take out a steady sound reasonably well and give up to 12dB improvement. BUT, it must be a steady sound, like mains hum or air con compressor. It won't help you beat a tolling bell because of the change of harmonic structure between the strike note and the hum chords. At best you'll treat the hum chords but then the strike will sound tinny and even more intrusive.

Trust me, I'm a bell-ringer

Thankyou for that advice chaps. I'll download the Cooledit trial anyway, I like the sound of it (no pun).

Good job I recorded the bell soundtrack on my spare camera, as always. At least I have a reserve.

Cheers, Red. (not a campanologist)
