Audacity Forum

Aha,just new too....Glad to see it!Thank you !

while im here, is there such a thing as anti latency, my computer had started recording tracks that didnt slow down but started getting ahead of the rest of the tracks. as the increase in speed was gradual there was no way to line up tracks as the speed was always different. very annoying. any way around this problem? (if my repaired computer still does the same)

This is not a latency problem, but it's hard to say exactly what causes this behavior. It's not common, but we do hear about this issue from time to time.

The best I can figure (and the jury is still out) is that it's an issue with your sound card hardware. If the clock signal for the input and output stages doesn't exactly line up, then you'll get tracks that drift in and out of time as they're being recorded. There are other theories about the cause, but in every case that I've heard the problem went away if the user bought a new sound card or audio interface.

On the other hand, I haven't been around on this board as often as I used to, so if there's a definitive answer out there for this issue I'd like to know please.

Is it solved already?:
I am just doing little research on gradual out of sync problems,
seems we both should try recording at 48000.
Make sure you do recording and playback on the same soundcard.

I think so,
most of the problems i had i think can be attributed to the sound card.
I purchased the behringer UCA 202 as a cheap replacement and so far i have not had any major latency or "anti latency" problems but i havent had a lot of time to play with audacity lately (Having a baby will do that ).

For the record i'm not that keen on the UCA 202. It would be great if all i was doing was converting tapes to digital formats or doing stuff that requires single track recording and small projects, but for multitrack recording its not the best thing on the market (but it does do the job and the price no one can argue about)

Hi,

I was actually experiencing the same problem you mentioned in your post. When i was recording the 30th layer in audacity, the music wont play properly. It did think of a solution but i need all of your advice..

I was thinking of exporting the file as WAV, and then reimport the WAV into audacity again to do another few layers, and then you repeat this process over and over again until you are done. But, i am not sure if this will affect the quality when you playback. Could someone give me some tips on this matter please?

Your computer is reaching its limit (if it's a fairly powerful computer, it's probably disk access speed).

Save your project as "backup.aup" (just in case you need to go back to this point)
Then save your project again as "new_name.aup"

Select some of the tracks that you are absolutely sure do not need any individual edition and from the tracks menu (Audacity 1.3.x) select "Mix and Render". This will mix the selected tracks down into a single (mono or stereo) track.

This is the equivalent of "bouncing tracks" on a multi-track tape machine, except, being digital, does not suffer the same quality loss that you get with tape.

You have now reduced your number of tracks, and so long as you still have plenty of free disk space (check this from time to time) you can continue adding new tracks.

Hey, I know this topic is really old, but I am having the same problems with tracks not lining up
even though I am playing in time. However, this problem happens to me when recording only 2
tracks. I record one, and then when I record the second, it lags. For example, I record a drum
machine set to a tempo of 120 and then I record a guitar riff to it and it is good for about 5
seconds then it starts to lag. To make sure that it wasn't just bad timing on my part, I started
over and recorded the drum beat and then opened another track and recorded the same drum
beat (both using a drum machine set to a tempo of 120) and the second one lagged. I am extremely
frustrated because I love recording but I can't get it to work. I even tried downloading other recording
programs and I have the same problem. What should I do??

thanks,

Miles

It sounds very much like the problem is with your sound card AvenueK.

My guess is that you are using either on-board sound, or a faulty sound card. If it plays back at a different speed to the recording speed, or the speed varies over time, then the problem is caused by the sound cards clock (timing) chip being too inaccurate. If that is the case, then the only solution is to upgrade the sound card.
