Removing audio whine? at DVinfo.net

Matthew Groff · April 21st, 2003, 07:19 PM

Hi,
I have a GL-1 and most of my audio has a noticeable whine that seems to come from the camera itself. Has anyone figured a clean way to remove this? (ie. eliminating a certain frequency). I have SoundForge and am decently skilled with regard to audio. Thanks.

I use Cool Edit Pro. With it I sample the noise and then use that sample in the noise reduction tool. Not sure if Sound Forge works the same.

If it is at a specific, single frequency that is outside the range of desired program you could apply a notch filter.

I just relpied to a similar post here is a copy:

First off I'm a audio geek at heart (of 20 years) and have dived into video in the last year to great success thanks to Vegas.

Sonic Foundry Noise Reduction is exactly what you need. Feed it some of the hum or noise and it builds a "noiseprint". It will then remove it from your recording. You can even solo just the noise that is being extracted to make sure you're not removing important stuff. I use it when I transfer LPs to my computer. My B&O turntable has a bad connection somewhere and it's a bit noisey, SF Noise Reduction takes that hum out and still leaves the rest of the frqs. It like magic. It's one of those plugins I have that sent shivers down my spine when I first used it.

good luck
