fix(editor): Apply window to spectrum before IDCT, not after
Fixed comb-like pattern in web editor playback by matching the C++
synth windowing strategy.
Root Cause:
- C++ synth (synth.cc): Applies window to SPECTRUM before IDCT
- JavaScript editors: Applied window to TIME DOMAIN after IDCT
- This mismatch caused phase/amplitude distortion (comb pattern)
Solution:
- Updated spectral_editor/script.js: Window spectrum before IDCT
- Updated editor/script.js: Window spectrum before IDCT
- Removed redundant time-domain windowing after IDCT
- JavaScript now matches C++ approach exactly
Result:
- Clean frequency spectrum (no comb pattern)
- Correct audio playback matching C++ synth output
- Generated Gaussian curves sound proper
