Re: [ARSCLIST] extracting audio from 32kHz 12bit DAT tapes digitally

[Dave Rice <dave@xxxxxxxxxxxxxxxx>]

I didn't want to do an D-A-D conversion, whether the sound quality is  
good or not. A digital only workflow makes a better workflow since I  
don't need to determine audio quality, set levels, etc. Also some of  
the D-D workflows can happen at faster than real time and retrieve  
the metadata on the tape.

The problem I had was related to DATXtract software. It would give  
errors for long play 32kHz 12 bit recordings.
I have since installed ubuntu/linux onto my Mac, installed read_DAT  
and can now pull off 44.1/16, 48/16, AND 32/12.
It separates the files according to the start/stop markers (which  
running SPDIF out through audacity can't do).
And it generates detail files that provide the metadata of the tape  
including the recording time which is very helpful for cataloguing  
(with an d-a-d workflow this data is also lost or likely never  
identified).
