Re: [ARSCLIST] Archiving at double speed

["Scott D. Smith" <lists@xxxxxxxxxxxxxxxx>]

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.
