Problems Recording from Dat player

Post by Hydroscope » Wed Oct 07, 2009 8:44 pm

Hi,
I have been dumping dat tapes into Audacity version 1.3.9 being run on a 2.8ghz Intel Core 2 Duo IMac with OSX 10.5.6. I don;t have any problems until i try to transfer from DAT tapes that had been recorded in "long" mode @ 32,000khz. When I set Audacity to Rec/Pause, there is no sound though I see the meters moving on the DAT. I checked the prefs and set both Hardware and Software playthrough in "Recording" and tried different sample rates in "Quality" section. I don't have any problem with DATs recorded in 44000 and 48000khz, only with 32,000. Any ideas?
Thanks,
Dan

I assume you're using the digital input on the iMac? If you're using analog in then I'm stumped.

In the Finder, go to Applications/Utilities/ and open Audio Midi Setup. In the Audio Input section set Source to Digital In and then see if it will let you set Format to 32000.0 Hz. If not, you're stuck using analog in for the LP DAT tapes.

Are you using the SPDIF connection on your Mac? That makes one in a row. I don't know anybody else who does that. DAT machines speak Broadcast AES/EBU sound and so does your Mac. We have DAT in our video machine room and it will speak to any of the multi-thousand dollar video decks with no effort.

At home, it's harder. Almost everybody in the world transfers work with the headphone port and some sort of analog connection. Macs do this particularly well as the analog Line-In connection is top quality. If you were reduced to doing that, there's no reason you would be able to tell the difference.

Extended Play is a curse. Everywhere.

I wonder if Audacity supports 32000 and DAT supports 32000, but SPDIF doesn't. There's no reason I know of why just those tapes would be broken.


Oh, wait. Never mind. Audacity does not support 32000. Do you have QuickTime Pro? QTP adds recording abilities and that may be the Get Out Of Jail card.
