Got some wonderful help here before so I thought I'd post about a new problem I've encountered, this time concerning audio.
I am converting PAL VHS tapes to digital files, using a JVC HR-S8500 (with TBC) hooked up with an S-video cable and RCA audio direct from the outputs (no SCART converter), capturing them to AVI files which I then process.
I have gotten an audio artefact that I think is identified as a "crackling" - could be wrong though. Seems to mostly affect dialogue for some reason. See the attached sound clips for examples (clip 2 has sound that is fine until the voice is heard).
At first I thought the input audio levels were too high, resulting in a peaking or "going through the roof". But even when adjusting the settings in the capture software to really quiet levels the problem still occurs...
The VCR is set to HIFI L/R with Spatializer Off. I want to keep the HIFI sound as the "normal" audio mode sounds pretty bad. Turning on Spatializer seems to worsen the artefacts slightly.
I've tried using different software (Goldwave, ClickRepair, Audacity, WaveMax) to restore it, with different pop/clip/crackle filters and using a frequenzy analyzer to attempt to find the noise, but to no avail.
So my questions are:
1. Can this be prevented in the capture process?
2. If not, can it be fixed with processing?
Thanks in advance!
