  1. I'm using an advc-100 to convert my VHS colllection to AVI.

    The process of audio noise reduction is not a problem as I run a small recording studio, but how do I accomplish the 'splitting' of audio and video so I can work with the audio directly? And how is the de-noised audio re-integrated with the video after doing this?

    Any software recommendations appreciated.

    Thanks ~ John

    Depends what software you have.

    I use sound forge, which can load .avi files for audio work. You can also use virtualDub (I prefer VirtualDubMod) to dump the audio out to an uncompressed wav file.

    Generally, if I need to work on the whole audio track, I split it off, fix it in SoundForge, then load it into Vegas (my editor) and replace the track that was there. In Vegas I finish the mix, and output as either 2.0 or 5.1 AC3, for loading into my authoring program for DVD compilation.

  4. Goldwave does a great job of cleaning audio from video. It can load the AVI and convert to a wav file. Before saving use the filters in Goldwave to clean the audio, save a wav and reimport the wav back into your NLE.

  5. Wow - that was fast! Many thanks folks.

    I'll try Soundforge for starters. As an effective noise removal tool I find Waves Audio Restoration DX/VST superb, if a little pricey. It strips out all kinds of gunk very easily.

  6. Thanks lordsmurf - got 'em .

    Although I can use Audio Restoration as a plugin in Soundforge.

    Cheers

    I've been playing with Goldwave more and more. It always seems to make the output "tinny". It works better than SoundForge on REALLY HORRID audio (clips where noise is overpowering the audio) but for small corrections I think SoundForge is still far better.

    Goldwave is aggressive. It has definite uses.

    I capture using VirtualDub, then save the .WAV separately from the video, then frameserve VirtualDub to TMPGEnc, creating m2v+mp2.

    The extracted .WAV is first run through Cool Edit 96, where I do any required editing, and then match amplitudes between the left and right channels (the tapes I'm transferring are recorded in hi-fi stereo, and sometimes one side is slightly higher in level than the other). I then run the .WAV through Diamond Cut Audio Restoration Tools, where I usually just have to run a declicking filter to smooth out any impulse noise in the source audio.

    From there I convert to AC3 using ffmpegGUI, encoding at the same bitrate that TMPGEnc encoded the mp2 during the frameserving job. The resultant AC3 will be identical in file size to the mp2, so I'll discard the mp2 in favor of the AC3 for authoring to DVD.

    I suppose that I could tinker with some additional sound enhancement using DC-ART, but thus far the source audio in my original VHS recordings really hasn't needed much work. I'll probably do more with this once I start to tackle 1st generation tapes, that will be either stereo or monaural audio, depending.

    For something small, quick and simple, there's AVI2WAV.
