Re: [ARSCLIST] Archiving at double speed
Kevin,
Pretty much a bad approach all the way around. You would need a
reproducer with exceptional HF response to maintain anything even
approaching flat response over about 12 kHz. Also, if the tapes are
Dolby encoded, the decoder will not work properly, as you have shifted
the knee of the filter curve up an octave. (DBX, being a broadband
compander, might work, but I wouldn't count on it).
We have a Studer reproducer that will get out to about 30 kHz, and can
run at 3 3/4 IPS, but even that won't reproduce the full response band
that cassettes are capable of. On the other hand, if there is no NR
used, and you don't mind the HF loss, you could conceivably go this route.

Here's an ethical / quality question, if one wanted to speed up the archiving of a batch of standard cassette tapes by playing them back at double speed (3 3/4 ips), recording into a workstation, then resampling the saved files so they are at normal speed, what would be the consequences / loss of quality?
Thanks.
