[Dtb-talk] DTB Here and There

[T. Joseph Carter]

Wow Greg, what is your audio sampling rate to do it that quickly?  
If you played a C-90 back at 3.75 inches/second with 44.1 kHz, your 
effective sample rate is 11.025 kHz, which is reasonable given the 
source material, but even if you were reading all four tracks at once 
(doable with not too terribly uncommon gear), it's gonna be 23 
minutes or so.

At 96 kHz you could go to 7.5 inches/second with the same quality, 
but again you're looking at a little over 11 minutes of digitizing 
time.

I'd love even the four track 2x setup.  Presently I'm doing it two 
tracks and 90 minutes per tape.
