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 left to confirm on real hardware.

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

The spectrum these read now follows the real engine's pipeline, taken from wallpaper64.exe (Audio/SpectrumAnalyzer and Audio/SpectrumProcessor): same FFT size, band layout, per-group level tracking, smoothing and separate left/right channels. Still unverified: a side-by-side comparison with Windows playing the same audio, and whether WE's loopback capture and the Linux monitor source both see the signal before or after the system volume.
