I have a problem with Wavelab and Izotope plugins, and I suspect they are related to Wavelab, as the same audio with the same (only one) Izotope plugin (in this case the Neuton 4 Advances EQ) does not cause any problem with Adobe Audition - the computer remains silent and performant.
My setup in a nutshell:
Macbook Pro Retina 13" early 2015
macOS Monterey 12.7.1
16 GB Ram
512 GB SSD
Wavelab Pro 11.2
Izotope Music Production Suite 6
Normally my Macbook runs absolutely silently.
However, when I load e.g. the Neutron 4 EQ in the master section of the WL Editor, the fan starts to work pretty heavy, the sound of the fan is disturbing (the computer does not get hot, the fan works fine), and the CPU load of WL increases by more than 70% (that of the WindowServer process by approx. 15%). The Neutron 4 EQ window is hidden to avoid generating even more load.
As can be seen in the screenshots, the audio processor load in Wavelab is not high.
At first I thought that my Macbook might not have enough power, so I did a test with Adobe Audition, which I don’t normally work with, and - as mentioned above - it runs perfectly and silently.
Do you have any idea what the problem could be?
Thank you in advance and best regards
