Author Topic: Transfers to WAV file faster than recording. (Read 6238 times)

phishn · « **on:** August 05, 2003, 08:28:47 PM »

Hi,

I'm having an issue regarding transferring from DAT to PC. I am using a Sony D8 DAT, an OADE DIGI I/O -A, and a 1 M cable going to my soundcard's SPDIF/IN. I checked the DAT and the record speed is 44.1. I create a WAV file with the same speed, play it back, and it sounds fast. Any ideas what's causing this?

Thanks,

Greg

make sure the sample rate on all three of these things are the same:

1. The Dat
2. Your recording software
3. Your soundcard

hope that helps...

Thanks Hank,

Only problem is that I cannot find a setting for my soundcard. When I play the dat, the sound is fine through the PC speakers. However, if I record a wav file and play it back, it plays fast.

most likely the soundcard settings are somewhere in your control panel.... also, forgive me if I insult your intelligence with this, but it does not matter what the little switch on your D8 says the sample rate is - hold down the play button and the tapes sample rate will pop up. Ive just seen people confuse this before.

But, again, your settings are somewhere in your control panel - I cant give you exact directions since I dont know what kind of card you have and dont really have any hands on experience with anything other than an Audiophile2496.

Thanks Hank. Yes, i pressed the play button and got 44.1. Something must be funky with the sound card.

any luck finding your soundcard settings in the control panel??

Try and find a copy of Creative Lab's WaveStudio...it overrides issues like that and reconfigures your soundcard on the fly if there's a discrepancy between your deck and soundcard....

Peace

What type of soundcard do you have?

phishn · « **Reply #8 on:** August 06, 2003, 05:54:34 AM »

The soundcard is integrated with an Asus A7N8X Deluxe motherboard. Its a soundstorm dolby digital audio chip.

I know its been said, but your issue prolly lies in the sample rate setting of your soundcard.

The reason it sounds fast is because your sound card is sampling faster than the D8 is playing.

I will occasionally make the mistake of not changing it before recording to my hard drive and I get the exact same results. My delta dio soundcard icon is located in the bottom right corner near the clock. Play around with its settings and you may find your answer.

The only other thing I can think of is when you are saving, you have it set to 48. I have also made that mistake. So, when you are saving in whatever software you are using, be sure the SR is set to 44.1 also...

Hope this helps!

Must be the soundcard. Only problem is that I see no settings for the soundcard whatsoever to change the sample rate.

If you cant find it yourself you can always turn back to the handy dandy manual that probably came with the soundcard or call customer support. Just tell them your problem and ask where to find the sound card settings, specifically sample rate.

good luck!!

I have read the manual and opened up a ticket with Asus. This soundcard allows dolby digital 5.1 recordings from sources. Unfortunately, I believe the sample rate is set at 48 Khz for this stuff.(even though I'm not using it.) I'm not sure if its changeable or not. There is no place on the sound control panel or in the manual that has a sample rate setting. Here is what the control panel looks like and what the choices are.

LOL...thanks Hank

The asus is the same card as the Zoltrix Pro 6. I had the same issue with it and never got it to work properly. The bigest issue is that that card did not lock onto a external word clock. SO rather than lock on the DAT it would use it's own or the pc. So there seemed to be some speed issues. I never got the card to work right and went another route. I know folks have gotten the Zoltrix to work stable, but I never could.

The Asus site says The A7N8X uses an onboard Realtek® ALC650 audio CODEC

A different chip - don't think it does bit accurate s/pdif transfers but it doesn't sound like that's your problem anyways. If it was actually sampling at 48k and you were only feeding it at 44.1, I think you'd have lots of zeros in there. If it sounds fast, my guess it that it's actually 44.1k file with a 48k wave header.

Open it up in something like Cool Edit Pro that shows you the sampling rate. If it says 48k, change the rate to 44.1
Note - don't resample it, just change the sampling rate (it should be an instantaneous change - no processing required). If your computer starts working away, stop it...you want the other kind of change.

Thanks David, the audio I have and motherboard is the A7N8X deluxe. Its a nvidia Soundstorm dolby 5.1 chip.

Thank you all for helping out a newbie with this uncharted territory. Looks like I'm gonna purchase an Edioral ua-1d instead. Time to check the yard sale!

RRobar · « **Reply #19 on:** August 06, 2003, 11:05:51 PM »

Now you are probably aware that the UA-1D is NOT bit perfect this may be a non issue for you. But just so you are aware. The UA-1D is a really nice lttle piece of gear. I borrowed Brian Costigan's for my Phish ALpine>Creek run. Came in very handy and was a snap to use. I am considereing getting one for travel just so i can make car copies with the laptop if need be.

phishn · « **Reply #20 on:** August 07, 2003, 06:49:50 AM »

Hmmmm. What transfer method is bit perfect? Any suggestions besides the UA-1D?
