Hum in interview sound

Ishnyk wrote on 11/30/2002, 2:14 AM

Hello,
Can anyone tell me if a low hum in an interview sound track can be removed using VV3. I think the hum noise was caused by the lapel microphone not being fully plunged into the camcorder.

Also, Has anyone used the Dells w/Pentium® 4 Processor with HT Technology @3.06GHz

Thanks,
Wally

For the type of noise you describe, you might be better served by purchasing the Sonic Foundry Noise Reduction Plug-in. It's a little pricey, but it sure did a great job of ridding some very noticable camera motor hum and other background noise I had in one of my projects.

I agree that Noise Removal would help. If it's a pretty "pure" tone, one of Vegas' EQ plug-ins might be able to do a fair job as well. There are already some presets for 60Hz hum removal with a notch filter, specifically.

Noise Reduction is a MUST HAVE tool for any video editor or musician from my perspective. Fridges, Air conditioners, AC hum, camera motor noise, lens zoom noise, air vents, car engines, all can be easily removed with exceptionally high quality. On the VASST tour we showed a clip with a fridge hum in the background that was completely removed with 2 passes of the Noise reduction. Wasn't audible, and wasn't visible at all on the finished wave form.

Apply a notch filter at 60Hz at a very narrow bandwidth. If the hum is not filtered completely, try a multiple of that frequency (120, 180, 240, etc)and that should take care of it.

Not to knock SF noise reduction, but a complete forensic audio application can be purchased from Tracer Technologies (Diamond Cut Audio Restoration Tools) for under $200, which includes a very useful spectrum analizer for finding exactly the frequencies you're interested in cutting/enhancing, high pass, low pass, and notch filers, continuous noise filter, impulse filter, compressor, paragraphic EQ, vacuum tube amp emulator, and much more.

"Noise Reduction is a MUST HAVE tool..."

I agree, based on my one-week trial period with the plugin, during which I was transfixed by its possibilities for me, an analog sound engineer from the seventies (am I dating myself??) Alas, until the price is halved or there is a "sale", I am limited to only those memories and the manual techniques that have served well over the past three decades . . . .
