Title: Dignoise! But not on master! WTF!? M1 + AP-2496 content.
Post by: sullen on June 10, 2005, 06:02:09 AM
Ugh.

I need some advice, im new and not very technicaly inclined!

Keep getting sharp, but not often, bursts of dignoise on a tape ive been trying to transfer!

This is not on the master tape.

Each time i try to transfer it, it appears in the same exact spot
really starting to drive me crazy,any advice would be great.

I thought maybe it was a cable moving around or from touching the computer while transfering.
second transfer i secured all cables and didnt touch the comp through the whole tape, and they were still in the same spot.

Any help/advice would be Greatly Appreciated, and DONT tell me to get a JB3, not going down that road.

4 second wav file attached. and pictures of ap's control panel

Running:
M1>sony 7pin>monster digicoax>maudio "breakout" cable into AP2496>sony viao p3 desktop>soundforge 6

Im also transfering a 48k master tape to 41k for cd audio, could that be it?


here is a 4 second sample of diginoise in wav format (less than half a MB in size)
right click save as

THese always appear in the same exact spots which arent on the tape.


Here are some screen shots of my soundcards controls:

I had a similar problem with digi-noise after installing a firewire card on my pc which ended up sharing the same IRQ with my 2496. I would also change the sample rate to match your master tape and switch the digital output format back over to "consumer". See if that helps.

First of all not sure what soundcard you have but most of them do not do on the fly 48KHz>44.1KHz resampling.  You will need to transfer the DAT at 48KHz and then resample it with software, myself I use Soundforge but there are many other quality programs out there. 

Secondly if you are getting digi-noise in the EXACT same spot each time then listen to the tape itself to see but it sounds like whoever cloned you the DAT did it then (if as you say it is not on the master DAT).  If that's the case then you'll need to get him/her to make you a copy of the show again.

But wouldn't that cause random digi-noise?  He siad that his problem is in the exact same spot everytime.

I'd also switch it over to consumer but it probably won't fix your problem.

I dont know what an IRQ is, but the 2496 is just connected into a port in the comp alone......
ill try to change the sample rate and consumer and see what happens thanx!

I'm using soundforge as well.
So you mean, set the S/PIDF sample rate on the card to 48K
and the "recording attributes" in Soundforges wav recorder to 44.1k?

It's my master.
I listen to it on the Dat deck and hear none of these noises.
I listen to the wavs the computer creates and there is the dignoise.
Did two transfers and the noise is in the exact same spot.....


Thanx for the replies!

Set the S/PIDF sample rate to 48K and the recording attributes to 48K.  EVERYTHING has to be set at 48K.  Once the show is on your hard-drive at 48K THEN you use Soundforge to re-sample the 48K wav file to 44.1K.

Sorry I thought I read somewhere that yours was not the master.  I don't know what to tell you if you keep getting digi-noise at the EXACT same spot every time and your master is clean.  That shouldn't be happening.  Maybe someone else can suggest something about this problem.

The m-audio website has lots of info on this very problem:

Pray for your sake that those suggestions do the trick.  The IRQ stuff on the website is a big headache.

Crap, I also meant to add that maybe the way the diginoise is happening in the same spot every time is due to differences in the clocks (internal and external).

Everything you have set is the same on mine.  Sounds like it's on the master.  Is it only that one spot if so just take care of it with soundforge.

HI!!!!


If it helps anyone out, i did just this ^^^^^^^^^^^^^ as Burnt said.

Set the SPDIF to restore defaults and professional.

Set the SPDIF sample rate to 48k on the maudio control panel.

Set the recording atributes in Soundforge 48k.

Recorded in soundforge at 48K

Downsampled in Soundforge and everything went fine w/ no speed/pitch issues or dignoise.

Thanx to all.
BIG thanx to Burnt

Hey Sullen
Glad it finally worked out for you.   :realhappy:
Just make sure that whatever sample rate the DAT is that you have everything else set to the same sample rate.   ;D

I use this same card, and have once or twice experienced this problem when forgetting to change the sample rate as occured here.

As for the comment quoted above, this is true.  If you use SEK'D Samplitude Studio, however, you can resample on-the-fly as the playback is being recorded to your hdd.  Just a tip that saves a  step.  SoundForge does not support this?
