Those are some loud noise bursts! Even if you found a good filter to reduce the clicking/buzzy parts of the audio, I would think the audio underneath those loud noises would also be drastically reduced as well. I say that because the noise is as loud, if not louder, than the audio you want to keep. Possibly it could be done if the voices and the noises are in two completely different parts of the sound spectrum.
Sound Forge has ways to show the noise profile, which may tell you what frequencies the noise is strongest in. If you got lucky and found the noise was at say 7 KHz, you could apply a filter to drastically reduce those frequencies and not impact voices, which are at much lower frequencies.
But before trying to do that in
Sound Forge, which is an awesome tool, I would first try what was suggested by timtape to get a better audio capture to start with. This involves trying to adjust tracking and/or changing the audio track from HiFi to Normal if the HiFi doesn't play click/buzz free on any manual tracking setting.
If not already available on this site, here's a link to page 18 of the manual for your VCR model
https://www.manualslib.com/manual/84...page=18#manual This shows you how to do manual tracking and to change the soundtrack selection. Other pages, such as page 16 (and others) show the remote layout. Looks like you've got the same button layout on your remote, but some of the keys have different symbols/letters on them. Hopefully those key positions on the remote still behave the same even if the symbols/letters in the manual don't perfectly match.
First, keep the player in HiFi mode and try many different manual tracking settings, ignoring the change in picture quality, to see if there is any setting where this audio interference goes away. If you find a setting that does this, use that and recapture the video even if the picture's bad. Why? The HiFi audio is far superior if you can get it without that interference. If you are successful with the audio, but the video's worse than the other capture, you can take the video from the first capture and replace it with the audio from the second capture. To do that, you open 2 instances of
Virtualdub and clip whatever beginning and ending frames you need off the files so that they both start and end on the same frame with the same number of frames total. Then you can save the audio only to a .wav file from that second capture. Then you can change the Audio setting in
Virtualdub to use that .wav file as the audio for the video you opened in the other copy of Virtualdub. Use Direct Stream Copy mode in the video menu so that you skip any video re-encoding. Once those settings are selected, just do a File Save As to a new .avi file.
If you cannot get a good HiFi capture from adjusting the tracking, then use the Soundtrack Selection feature to put it in NORM mode. This should play the non-HiFi audio track instead of the HiFi track. The fidelity won't be as good and the audio may be at a lower dB level, but it would hopefully be free of the clicking and buzzing. You should start with Auto Tracking re-engaged first. If you still get audio noise, try manually adjusting the tracking again to try and remove that. If you are successful with this, you can either use the audio meter in Virtualdub and your audio capture settings to increase the sound level so it's closer to where you want it, or you can use Sound Forge later to add a few dB to the entire audio to get it closer to the levels you had for HiFi.
Best of luck to you!
