Hi Eli,

I've been following this discussion but haven't weighed in until now. I do all of my transfer work - from both analog and digital sources - to a Tascam DA-3000 digital recorder. I then copy the files from the recorder's memory card to my computer for editing and processing. The Tascam DA-3000 has a built-in, switchable, sample rate converter, which should have no problem dealing with your 32 kHz input. What I don't know is how it will deal with the 12-bit, non-linear datastream. But, if you knew someone who had this recorder, it would be interesting to give it a try. 

One other thought: Is there pre-emphasis on those recordings? If so, the sample-rate converter in the DA-3000 will automatically do the de-emphasis during transfer, at long as the DAT player passed the pre-emphasis flag to the S/PDIF output. There's no mention of this in the Tascam manual - it's one of those "undocumented features."

I've used the DA-3000 for some transfers of old PCM-F1 format digital tapes, using a PCM-601 digital processor, which has an S/PDIF output. The DA-3000 takes care of the sample rate conversion from the F1's odd-ball 44.056 kHz sample rate, and does the de-emphasis. 

It might work for you - it's just a thought.

Best,
Gary Galo

Hi Eli.  I was recording DA-88 (48K), not DAT.  My setup was a Digidesign
192 I/O using TDIF from the DA-88.

You have a special case with the 32K DAT.  Keep us posted.  Regarding clocking, you shouldn't need work clock.  Your card should be able so sync to the incoming S/PDIF.
