: audio help?

Hi folks,

I have some very old VHS tapes from 1987 - the clients recorded on the LP setting so the quality is not so great for both audio and video. I've done what I can on the video, but there's a buzz on the audio which I can't seem to eliminate enough to my liking.

I've used the 31 channel EQ setting in Final Cut (5.1.4 is the version I have) and it's reduced, but I can't seem to get it entirely. Reducing -63 and -4000 to 0 has helped, but it's still there. I can't quite make out if it's electronic humming from the original camcorder used or if it's just b/c the tape is so old and recorded at the wrong speed (meaning lower quality).

I'm in the midst of posting a sample to provide a link so you can hear it first hand, but in the meantime, any other suggestions ie. filters? or otherwise?

cheers,
Keebler

just thought i'd bump this in case some folks didn't see due to server switcheover.

If you have a section of the hum/buzz by itself -- even a short sample where there's no other noise but the buzz -- Amadeus Pro and SoundSoap can both identify and filter it out pretty effectively.

I use SoundSoap for a variety of different audio purposes and it works quite nicely.

thanks guys. I actually like SSoap, but i think this is the best I can do. I'll try with SS. I showed the clients and compared to the original track (in which the buzz is downright terrible - in fact, it drowns out most of the spoken audio). They're happy with it now, but I told them I would try one more run.

Thanks!

I've tried your audio sample with a combination of equim and izotope eq and izotope noise removal and managed to get most if not all of the noise out.
