Enhanced AudioAnalyzer with bass chroma, integrated chroma, and chord frame accumulation for more robust and stable chord detection. Added spectral peak note estimation and note continuity logic. Refined chord scoring and introduced chord lock mechanism to prevent rapid switching. Added methods for tuning reset, set, and snapshot retrieval. Updated SensitivityProfile with chord lock parameters.
In Game1, added keyboard shortcuts and JSON persistence for detection tuning profiles. Improved HUD with confidence bars and new indicators. These changes increase detection accuracy, stability, and user customization.
Expanded chord detection to support 9 chord types (maj, min, sus2, sus4, dim, aug, 7, maj7, min7) with updated scoring and voting logic. Added pitch-filtered FFT path for improved tonal analysis. Introduced real-time, per-mode tuning of detection thresholds (harmonicity, separation, vote consensus) via keyboard shortcuts, with HUD display of current values. Refactored chord display and voting logic to handle expanded chord space. Added thread-safe tuning adjustment and helper methods. Overall, improved flexibility, accuracy, and user control for audio analysis.
Adds temporal voting queues and aggregation logic for note and chord detection, improving stability and reducing spurious results. Enhances chord detection with new harmonicity, peak ratio, and separation checks. Introduces HPS-based fundamental frequency estimation. Updates SensitivityProfile with new tuning parameters. All changes aim to make detection more reliable and musically meaningful.
Added FodyWeavers.xsd, .dotnet-home/.dotnet, .dotnet-home/.dotnet/TelemetryStorageService, and .nuget to .gitignore to prevent tracking of generated and tool-related files.
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.
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.
