@Natan Just out of curiousity.
What is the difference between boxblur and gaussianBlur?
The effect seems the same with the snippets you provided that's all.
I tried the snippet in HISE using my windows 10 virtual machine and eveything glowed like it was straight outta the 1980's. Worked fine!
@ulrik Yep pretty sure I did!
Here's a screenshot of the preferences of a recent project running through HISE on Windows 10 Parallels.
The project makes use of the 'Audio Analyser' floating tile which (if I'm not mistaken) requires IPP to be enabled. As you can see in the screenshot above, the 'Use IPP' flag is ticked and enabled.
Compilation works fine without errors.
