Apologies if this subject has been covered before, a search has yielded no results on the issue.
Firstly I’m using Cubase 13 pro, latest version.
I have all my projects set as default to sample rate 48k (24 bit).
I was tracking recently and noticed the track was detuned and running at a different tempo.
A quick check revealed the sample rate was at 44.1k (24bit) not the 48k I’d started the project at.
Obviously I changed it back and then had convert all the files. Everything was fine but obviously this was odd.
Yesterday I was overdubbing with a client on a different track and upon loading the project, the whole song was pitched up and running at a faster tempo. Yes, the sample rate has once again changed to 44.1k.
Obviously there’s no keyboard short cut to changing the sample rate that I could have accidentally pressed, so I have no idea why this is happening but I can’t keep converting back and forth every time this glitch occurs.
Anyone got any thoughts on what would cause this please?
I do switch between drivers. UAD and ASIO depending on where I am and what I’m doing but surely that’s not changing the sample rate.
I can’t say I know why you sometimes experience a sample rate mismatch but I would guess it has to do with:
I also wonder,
Why would you have to convert the audio files? It is only when there is a mismatch between the project sample rate and the audio files you would get playback at the wrong speed. Just changing the project sample rate should take care of that.
That’s the confusing part, that even when switching back to my original sample rate, the audio needs converting. The first time, it was only a quarter of a step out of tune. Not even a semi tone. Second time sounded like a drum and bass remix, with Mickey mouse on vocals…
But even when switching sample rates, it wasn’t corrected.
I’m pretty sure you’re right, it has to do with driver switching and it’s only happening since I switched from an SSL interface, to a UAD one. On UAD interface, the sample rates aren’t selected within cubase but on the UAD console software. I’d speculate that’s the issue.
I suspect something else was going on. I have never heard of a case where Cubase decides to change the sample rate of audio files all on its own.
If it does happen again, check the Audio Pool. It will tell you the sample rate the files/clips were recorded in. Then change the project sample rate (and interface if necessary) accordingly.
That is likely the issue then. I suppose you just have to be diligent and make sure the UAD sample rate is set correctly before staring Cubase.
Also which, I missed out from the original post, when I checked the project sample rate in Cubase settings, there was an exclamation mark (!) next to the sample rate. So cubase knew that there was an error with thesample rate. Anyway, definitely swaying towards the UAD software resetting sample rates. I guess I’ll have to check every time I launch it…
Thanks for your input and taking the time to respond…
