drifting tracks... please help!

Posted on

Member Since: Feb 03, 2005

I bought a Sony Vaio VGN-A150 with recording in mind. It has 512 MB of RAM. Soon after, I bought a Creative SoundBlaster Audigy 2 NX. When recording into any program, one track always drifts. They never, ever match up, making recording nearly impossible. I read that the SoundBlaster cards aren't great for recording, so I tried recording straight into the mic input on my laptop and had the same results.

Can I solve this problem by buying a new sound card? More RAM? This is driving me crazy. Please help!

Thanks,
Jonathan

Depends on the software being used. Some software such as Audition have a Correct for Drift feature.

By drift, I take it to mean that at the first of a song, the tracks are in sync; but by the end of the same song, the tracks are out of sync?

Or do you mean that you record one track, play it back while recording another track, and when both are played back the second track is out of sync with the first? If so, then this is caused by latency.

I have a feeling that you're talking more about latency. With latency over a certain number of milliseconds, the lag between you playing a sound and it being committed to hard disk becomes extremely annoying to work with.

If your Sound Blaster card supports ASIO, then select that as your input while recording. If not, then there are some drivers out there that greatly reduce the latency of SB cards. They're not officially supported, but you can try them out here: kxproject.lugosoft.com/index.php?skip=1

also here's something I just found that's kind of a shoehorn for ASIO support for WDM drivers: michael.tippach.bei.t-onl...4all/intro.html

yikes, soundblaster and vaio both in one issue, a double wammy...

well, the SB isn't a good device for recording, but it is most certainly better than the mic in on your laptop would be.

Also, isn't the kx project something about better ASIO for SB's?

As far as I can tell, KX project is improved WDM drivers, while the ASIO4ALL has something to do with using ASIO with WDM cards. I'm not sure how that works tho...

:edit:
upon closer inspection in the FAQ for KX Project, it does appear that it adds full ASIO 1 support and partial ASIO 2 support to WDM cards such as the Audigy 2 in question.

I do have a problem with latency and it is annoying, but you were right the first time: I match the beginning of the tracks up and they are off by the end. do you have any idea what could be causing this? I have tried everything I can think of.

if the links provided can help with this problem, I will try them as soon as I return home next week and let you know the results.

thanks for all of the help.

my audigy nx2 is external and therefore does not work with the kx drivers. and, as I mentioned above, the problem IS with drifting tracks, not latency... so, any other ideas? you guys are my last hope before I bitterly crawl back to my four track recorder.

OK Jonathon, sorry I missed this one.

First question I have is this. Does the added track seem to go further out of sync as the song progresses, or does it stay just a certain amount out of sync?

Even if you have matched the track up it may still be a latency issue.

One suggestion I do have is to check and make sure you are using the audio I/O as the recording and playback timing master. If you are not this can cause an issue such as what you are experiancing.

Something's wrong with the ADAC if you're left channel is recording a different length from the right channel (of a stereo source). It's not converting the analog to digital equally on both sides. Bad card. Bad, bad card. You didn't get any voltage thru it, did you, like from an amplified source instead of line?
