Improves audio analysis by introducing adaptive normalization and per-mode sensitivity profiles for spectrum, level, and band features. Adds temporal stability to note and chord detection, reducing jitter and false positives. Enhances note detection and visual feedback for whistling frequencies (800 Hz–5 kHz). These changes make both analysis and visualization more robust and responsive to varying input conditions.
Implemented chroma-based major/minor chord detection in AudioAnalyzer and exposed results in AudioFeatures. Updated HUD to display detected chord names. Added a new "CHORDS" fractal preset that visualizes the current chord with large pixel text, modulated by confidence and beat. Extended pixel font for chord display. Ensured graceful handling when no chord is detected. These changes enhance both analysis and visual feedback for harmonic content.
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.
Introduce a RenderQuality enum (Low/Medium/High) and allow users to switch quality at runtime via keyboard shortcuts. The fractal renderer now adapts its internal resolution, particle counts, and computational workload based on selected quality and real-time performance, aiming to maintain a target FPS. HUD and window title display current quality and FPS. Renderer buffers and limits are dynamically resized on window or quality changes for improved performance and flexibility.
Expanded fractal preset range to 20 with unique names and rendering functions for each. Added new visual effects including equalizer bars, metaballs, galaxy, aurora, vortex, laser grid, rain ripple, ink smoke, mosaic, ribbon, and grain bars. Improved CRT feedback with audio spectrum integration. Introduced utility and ring drawing functions. Updated preset selection and naming logic.
