I had actually been thinking about trying exactly that -- I do have a
good quality hi-fi VCR here still, despite the fact that I haven't
used it in years -- so I set it up yesterday and gave it a go. I
hooked my laptop up to the VCR, played the track while recording, then
swapped the connectors around, rewound the tape, and recorded the
audio from the VCR back in to the laptop.
It's amazing just how clean the signal from the VCR is. In fact, it's
so clean that it sounds identical to the original audio to me.
Comparing the signals in Japa, I can see a sub-50Hz hump in the VCR's
audio, and a slight roll off above about 10KHz. There's clearly some
stuff going on in the time domain, too, but it's very subtle, and I
definitely can't hear it myself.
So, an interesting exercise, but perhaps a pointless one :) I can
upload the audio if anyone's curious and wants to do their own
comparisons, though.
I had actually been talking about normal audio tape (1/4" half-track).
Hi-fi VHS is built a little differently, and I'm not sure it responds
the same, or how the media itself compares to audio tape (Ampex 456, for
example).
