OS Waves (3014738359) - Open Rendering Issue

The earlier investigation of this wallpaper listed six differences from the native Windows Wallpaper Engine. Script-driven user settings, text objects, the orthographic "auto" camera and autosize are implemented now, and skipping passthrough images without effects matches the real engine (CImage.cpp, sub_140175830). One item is still open.

Audio spectrum response may differ

The pulse effect on the three OS logos (objects 173, 57 and 61) uses:

  • AUDIOPROCESSING=3
  • audioamount=1.0, audiobounds=0.5-1.0, audioexponent=0.35

Nobody has compared the logo pulse against Windows side by side, so whether our spectrum analysis (Audio/SpectrumNormalizer) drives these parameters the same way is unknown. Checking it needs the same audio playing on both engines at once.
