Implemented musical note detection in AudioAnalyzer, exposing dominant note and strength in AudioFeatures. Updated HUD to display detected note. Added "NOTEDROP" fractal preset that animates detected notes as colored glyphs. Extended bitmap font to support sharps. Increased fractal preset count and adjusted HUD layout.
Implement real-time BPM (beats per minute) estimation in AudioAnalyzer by tracking beat intervals and smoothing the result. Display the current BPM in both the window title and the on-screen HUD. Update AudioFeatures to include a Bpm field. Adjust HUD layout to accommodate the new BPM information.
