Audio gets recorded BEFORE where it should be.

    Hey, first post here... I'm still a n00b at audio recording, so bare with me please... I've got an Audio Kontrol 1, using it with Cakewalk Sonar X1, and just starting to get it going. I've been watching some tutorial video to get me started, and after I learned some basics, I figured I'd give recording a quick shot. Well, I got a weird problem. After I put in a drum track, set the BPM and the metronome, record some audio and play it back, it actually appears BEFORE where it should be. The whole recording is like half a second ahead of where it should be. I've heard of latency, but it seems like I'm getting some kind of reverse latency.

    Any ideas? Any help would be much appreciated.

    Btw, I have a 2.4Ghz quad-core, 4gb ram, 2tb hd, windows 7 64-bit. Let me know if you need any more info.

    Latency refers to the delay in the monitoring of a live source between the time the sound is made and the time it is heard. What you are experiencing is not latency. In Sony Vegas it's called record offset and it can be adjusted in the preferences. Other software has other names for the same thing.

    Heh, I was sorta joking about the "reverse latency" thing, but I'll look for something in Sonar that looks like "record offset". Thanks.

    Under "Sync and Caching" preferences, below "Synchronization", "Full Chase Lock" is selected and the "Timing Offset" is on 0.000 msec. There is also a "Record Latency Adjustment" with a manual offset on 0.

    There is also something else called "Remove DC Offset."

    I also found a "Synchronization Overview" in the help file, so I probably need to go through that. I think the problem I'm having is with synchronization. Anyone have any tips about that or fixes to common problems?

    It won't be sync or DC offset. Record latency may be it. Does it allow positive and negative values? Does it specify a unit for the value, like ms or samples?

    Nope only positive values, and the unit is samples. It seems like something is not synchronized. I uploaded a pic of the preferences screen.

    Record Latency Adjustment sure looks like it. Maybe they didn't account for your problem, the new track being ahead of the earlier ones. Maybe some change in another setting will make it closer. Have you tried changing the Record I/O Buffer Size or Write Caching?

    You might want to try switching to ASIO drivers instead of WDM, assuming that's an option.

    Yep, fool with the driver and see what happens. I've had it happen that changing from one driver to another and back fixed things.

    Sync is a common problem with many causes. If you don't use headphones as a monitor, you can easily fix sync problems using this program... Synchronicity - Home

    Or you could just address the root problem so your tracks are always properly synced.

    UPDATE: I have temporarily made the program available completely free of charge so that people can use it and let me know what they think. Here's the link...

    I put the download link right at the top of the page. Enjoy!
