Recording new track to saved project in sync, when playback new track is out of time but in time by itself seperately

[Keeldaprezin2016]

Hello, new to forum, but used to record with audacity back in '09/'10 and really loved the user friendly software!
I have a macbook pro 2010 release running el capitan os. I used dell pc until recently. I have just began making music again recently using a discontinued korg ms1, acoustic electric dean bass and an audiobox 96 for my interface connecting to macbook pro via usb. I am plugged directly into the audio interface from ms1 via quarter in jacks. My problem is i have recorded a few tracks syncing up just fine, but after saving project one night, then opening the sav3d project next day and trying to record new cymbal track, which sounds perfect as i am r3cording, when i stopped and play back the new track is out of sync with the saved project. I have read up on this briefly and one suggestion was that it was the sound card. But having a macbook pro, shouldnt that not be the case? And i thought i should mention when i recorded the first time i used my speakers for playback and monitoring, then after saving and coming back to the project
And recording the cymbal track the second time i used my vintage MDR V2 headphones. Doesnt seem important but i dont know! I am new to this after being away from music production since 2010 and also new to mac OS!

Thank you for this wonderful software and very cool forum and support system!

To record overdubs successfully, it is necessary to set up "latency correction" so that Audacity can adjust for the amount of time that it takes for audio to get in and out of the computer. See here for how to do that: https://manual.audacityteam.org/man/latency_test.html

If you use the same hardware, same sample rate etc. then you will normally be able to set this and forget it. However, if your hardware changes or you use a different set up, then you will need to readjust the latency correction.

You are listening to the Audiobox 96 during the production, right? The Audiobox is producing the performance mix and you have to listen with analog headphones. No fair using wireless earbuds or digital headphones. Digital sound is coming from the computer not the Audiobox and it's always going to be shifted, late, or with an echo.

I'm curious how you set recording latency (the one in the Audacity setups). My favorite way is to jam my headphones against the microphone and record a rhythm or click track. The latency setting is the difference between the two tracks, added to the existing setting.





If there is no microphone, you can do it the slightly sloppier way of playing a live instrument in time to a backing track. Average out your response time and tiny timing errors.

MacOS Big Sur V 11.1 5(0C69) SSD hard Disk Audacity 2.3.3 Great Software !!!!
I am new ( Thursday Jan. 28 2021 ) on the Forum. At the moment I cannnt find the proper answer, thank yu in advance

Input & output through USB --> Diamon Sound Tube (a simple sound "card")

I observe/mesure exactly a different latency (typically 200-400 ms) , from time to time , when doing many recordings (while playing sumultaneously for play along/playback usage)
though WITHOUT change :
no change of hardware
no restart of Audacity
no change of Sample Rate
what else ?

The only (I believe) things I change are:
* the zoom in the window where I play and record simultaneously for play along or playback usage
* a New Window for the play along and recording tracks
* Put the Mac to sleep (a correct translation for the French "Suspendre l’activité d’un Mac" ? ... acording to gogol...)

Of course, after measuring it , I can compensate exactly (I use click tracks) but it is annoying and time consuming.

Even if no solution, I would be happy to know WHEN / HOW it occurs ????
Any hint ???
Thank you in advance !

Hi, it usually best to start a new topic, rather than hijacking an existing post. (You can always reference it, if it is relevant).

However, in this case, since you have received no replies so far, and since your issue seems to be what is affectionately known as "moonphase", I suspect no one has any insight into this matter for you.

Perhaps you will later find some way to reliably repeat the problem and then share it.

Importantly, you have a solution to the issue.
