Title: Slow DAT Recording Help.
Post by: momule on October 12, 2004, 06:34:16 PM

I Have one DAT that reads as 48 in my machine, but when recorded
it sounds slow.  I've checked the recording sample rates and all seemed
to be in ordder.  My thinking was maybe the machine was mis-informed
so I tried recording a piece of it at 44.1 and it also sounds slow.

So, it sounds fine when played, but when recored (in Cool Edit 2000)
at 48 or 44.1 it sounds slow.

Sony A6
Audiophile 2496

Sample rated have been cheked/adjusted in the control panel for the
Audiophile and in the software.

Ideas?

TIA.

Adjusted from / to what?
What is the actual sample rate of the WAV file?
Have you tried changing the sample rate (not resampling, just changing the WAV header's sample rate)?

you can try this:

if u have wavelab, record it at 48.k, then go to Edit>audio properties>cycle through the sample rates and see if you can get it to sound right.  You could also rec at 44.1 and do the same thing.  I've had luck doing this before on some files w/ some wierdness...

in response to Brian:

M Audio Delta Control Panel


(Harware settings tab)

Master clock = s/pdif in

s/pdif sample rate = 44,100
(note: if I set this to 48,000 I get zero signal from the dat)


Cool edit 2k

New @ 48, stereo, 16 bit


The actual sample rate of the recorded .wav file is 48

No I have not tried changing the sample rate in the header of the .wav file
How do I do this?

this is your culprit. your recording is at 48k and you're telling your 2496 that the incoming signal is 44.1k.

(note: if I set this to 48,000 I get zero signal from the dat)

try playing the dat first and change the sampling freq.
the 2496 should show "Locked" on the S/PDIF window.

also, in your Windows Control Panel>Sound Devices>Recording Devices should be set to 2496 S/PDIF in.
