But I distinctly recall that when we recorded tapes for sale
> using the tape deck from my Sanyo stereo (not on a PET BTW - this was a
BBC
micro) we
found that Dolby noise reduction had to be disabled for it to
work...
Did you try recroding with Dolby and then replaying on a machine with
Dolby noise reduction (turned on), or replaying on the normal cheap
cassette recorder that you use with computers? If the former, then I am
not suprised it didn't work - the frequency response would have been
rather odd. The latter should have worked, though. I can't
remember if we recorded with and played back with - I imagine that would
work
Should work. Because what Dolby does to the sound it undoes afterwards and
you theoretically have a recording closer to the original than normally
possible - without the extra hiss due to the recording process.
Theoretically you shouldn't lose any hiss from the original. But, even if
you did, the computer doesn't really need it.
- but we definitely couldn't get it to work recording without and
playing back with, although this actually works quite
well for music.
I've noticed exactly the opposite. Recording with and playing without gives
a 'crisper' sound.
But, doing any of these two would be altering the sound.
I would be
suprised if you couldn't make a CD that could be loaded. I
can't try it because I have no way of writing to a CD.
I never meant to imply that you couldn't make a CD that could be loaded.
What I meant was you probably have to be more sophisticated than old
cassette -> digitised audio -> audio CD. I'd recommend old cassette ->
signal restoration -> digital signal (0s and 1s sampled at some highish
speed) -> possibly prefilter to pre-emptively undo the CD player's output
filter -> digitised audio -> audio CD.
Possibly a better result. If you know
what you are doing.
