Hi everyone,
I've been trying to recover the original VHS dub of a cartoon I've grown up with.
I'm almost done, but I have a ~15-second "hole" that was missing from my first VHS (maybe the tape had gone bad or was recorded over). So I've bought two second hand copies just to digitize those last 15 seconds.
Both those copies have really bad audio, with an almost constant electrical buzz going on throughout them. It's a crackly noise that looks like this on the spectrogram:
I've attached a sample of the very audio I'm trying to recover. It's the same 20 seconds captured 4 times, followed by a clean sample of the buzz from a "silent" bit of the tape.
The VCR I use is a Panasonic NV-HS1000 that's been great for all my other tape captures, both audio and video wise. I'd love to try another VCR to test the audio there but I don't have another working one.
I've tried the Audacity Noise Reduction tool but it's been useless. the buzz is till very much there.
Is there any way of cleaning this through software?
Thanks for your help!
