Audio cleaning procedure? particular, procedure, recommend, effective

andy

Can anyone please recommend an effective procedure for cleaning up the audio in a VHS cap?

In particular, I'd be looking to de-hiss and possibly amplify it as I can't seem to get high enough audio levels during capping (using an AIW9000pro, SB Live and iuVCR).

Should I use VDub to extract the audio track to a WAV file, before cleaning it up then re-muxing during the encoding step in TMPGEnc?

Thanks,
Bob

For adjusting the audio levels and de-hissing in the wav file try CoolEdit2000.

Hi,

First you should try to make caps without hiss, so check your connections, the volume recorded, try other capture programs and drivers...

If that fails, demux your audio (or save wav) and do the corrections in another program before converting and muxing again, as bobspliff already said, you can use Cooledit or Steinbergs Wavelab for that.

I always use CoodEdit for this. Noise cleaning is pretty simple and very effective..

First you mark little part of your audio stream that should be completely silent..after that you open noise-reduction window (effects/noise reduction/noise reduction) and click 'get profile from selection' and after that you click 'close' NOT ok.
Then select the entire clip and go again to that noise reduction window and click 'ok'. Processing starts...

After this I also have to resample file to 2-channel stereo cause I have to capture only mono-file but maybe that's not the issue in your case..anyway always reduce noise always from single channel first if this is also your case cause it's little bit faster.

edit: of course you can try to de-noise only for little part of your audio too if you just wanna try the effect. Just dont mark the whole file when you start de-noise process..btw, I use default values in noise reduction -tab.
