Audio Peak/Overload

Question

Audio Peak/Overload

Is anyone experiencing random peak/overload of the stereo output?

In my case, it showed a peak of 522dB and 713dB.

It also produces a burst of sound that's very unpleasant.

Any ideas as to what this might be?

Mac mini, macOS 12.6

Recording in 44.1kHz. I use all of them... Let's say in this last incident I only used the Prophet and the DX7.

I've used the same setup on my Macbook Pro for years, and this never occurred.

Also, I've just switched to the Mac mini, and it happened twice now. I'm using a Universal Audio UAD Apollo quad thunderbolt audio interface. Just mentioning it, in case it's helpful.

The burst of white noise has been around since Logic 4.0 when the application was developed and owned by eMagic. Apple purchased Logic in 2002, around the 5.5 version. No one has ever figured out precisely what causes it. Logic's audio engine seems to lose sync with core audio, could be plugins not 100% compatible, could be the audio interface/Logic sync, could be the logic software version or MacOS version. Plugins seem the most likely but as you've found out, it can vary from machine to machine. Be careful the blast can damage hearing and speakers.
