Can someone help me with sound

[npcoombs]

Hi

Im just putting the finsihing touches on my edit of Bela Tarr in Conversation and am hoping someone here can lend me a hand with sound - something I am useless at.

In the auditorium there were ambient regular noises that are really dsitracting when you hear the film on a good sound system. I think the sound was coming from a fan that was near the stage.

But unlike normal ambient noise the regularity of this sound is really distracting because it sounds like a fault in the recording more than a syncretic feature.

Is there any sound whizzes out there that could find its frequency range and expel it from my sound file?!

Please help!

You need a noise filter rather than trying to EQ it which can make your voice track sound unnatural.

Have a look at this tutorial for noise removal in soundtracks:

Don'f forget to make a backup of your original audio before you tweak it.

Good luck.

i would try a combination of an adaptive noise filter and a simple noise gate, which is often very effective. it depends on the acoustics of the room though; if there's echo you need to look elsewhere since the gate will be fooled by that.

ps. audacity is my tool of choice for most simple audio stuff like noise reduction and speed changes. the tutorial posted above uses it too it seems.

To this day, Syntrillium's Cool Edit Pro has the best noise reduction I've ever used. It's not available anymore but it DID sell new for $250. It's been bought by Adobe and turned into the slowest, biggest resource hog on the planet. Fortunately I still have my CEP v2.0 CD.
