Cubase 12 metallic squeaks

I’m encountering an odd problem where a high metallic squeak will happen at random times during playback. I was able to capture it via real-time export. Here’s a short example:

Edit: another example:

Couple observations:

  • The squeaks do not occur if doing an offline export.

  • It does not happen during playback when playing the the same sessions in Cubase 11.0.41

Have there been any reports and do any solutions come to mind? I’m having a hard time pinpointing the problem but since it doesn not happen in Cubase 11, that leads me to believe that it’s something with Cubase 12.

System:
16" M1 Max Macbook Pro
Monterey 12.3.1
Cubase 12 (Rosetta)

Thanks

Adjust your buffer size.

I changed it from 2048, to 1024. Seemingly no difference. Tried 768 and 512 and the squeaking seems to occur less frequently. Hard for me to spend time playing the same songs over and over again to see if a squeak occurs.

Again, the sessions play fine in Cubase 11.0.41 at any sample rate.

Noting that I’m still experiencing this bug in Cubase 12.0.10.

just out of curiosity in Studio>Studio Setup, what is the clocksource set to?

Clock set to Internal. Just checked 11.0.41 and the settings are the same.

Okay cool, because if clocks are out of sync weird sounds can happen…

hmm…

just a thought, have you tried a different interface or just Windows device?

Appreciate your suggestion though! I haven’t been able to try another interface and don’t own a windows computer. However, since the sessions run perfectly in cubase 11.0.41, that leads me to believe that it’s not a problem with the interface or computer.

It could be a combination of new versions and interface/ASIO who knows.

It’s interesting to me that your Clock Source can’t be selected, why is that? What is your AD/DA setup? on V11 I can open that menu.

Also, have tried starting v12 is safe start mode?

Hi @NoiseCo , I cannot hear the metallic squeaks in the wave file you provided. Also, the frequency analysis shows no suspicuos transients. Can you repeat with a signal generator and record the metallic sound in a 200 Hz sine? I’ll have a look at it. Thanks!

@Anj - Not sure why my Clock Source can’t be selected but its the same way in Cubase 11. I’m using an Antelope Orion 32 HD via MADI to a RME HDSPe MADI.

Have not tried safe mode. Anything I should try specifically with safe mode?

@Chriss I’m unable to capture the squeaks with the signal generator. I’ve exported a different song via realtime export to capture and chopped up a few sections showing two squeaks. Since the song isn’t out yet I’ve kept the example short out of respect to the artist.

Another data point - switched the interface to built in audio and the squeaks still occur.

Unfortunately the squeaks still happen in 12.0.20.

Sorry to say, but with your examples it is very hard to provide any help…

I’m not sure that I identified the problem in your sample,
but what I possibly hear as the problem, could be a processing artefact,
not related to a bug or something similar.

Listened to both example files. Can’t hear anything that sounds like a squeak. :person_shrugging:
