What's New in v0.2.4

• Stem-Targeted Harmonies: Generate 3-part diatonic harmonies on either LEAD_VOCALS or BACKGROUND_VOCALS directly from the mixer channel strip.
• Dynamic Stem Indicator: Vocal Studio HUD displays the exact active target stem and musical key.
• Go Gateway Proxy Fix: Direct reverse-proxy forwarding through port 7860 for all harmony, spectral repair, and vocal character endpoints.
• Continuous Phase Vocoder Auto-Tune: Zero audio slicing, zero chunk boundaries, zero boundary clicks, and zero comb-filtering.
• High-Speed 3-Part Vocal Harmonizer: Generates +3rd Diatonic, +5th Power, and -8va Sub-Vocal stems in seconds.
• Adaptive Light/Dark Mode: Vocal Studio and Spectral Repair modals dynamically restyle for both light and dark themes.
• Consonant & Sibilance De-Ess Guard: Prevents sizzling/sparkling phase fuzz by automatically detecting and bypassing pitch-shifting on unvoiced consonants (s, sh, t, k, p, breaths), keeping them 100% pure acoustic audio.
• AI Singer Gender & Duet Detection: Real-time vocal acoustic classifier detects Male, Female, and Duet/Polyphonic vocal intervals.
• 3-Tier Color-Coded Karaoke Teleprompter: Words dynamically light up in Electric Neon Cyan (Male), Radiant Hot Pink (Female), and Golden Amber (Duet / Both), accompanied by active singer badges on the TV stage prompter ([♂ SINGER 1], [♀ SINGER 2], [👥 DUET / BOTH]).
• Interactive Singer Override: Clickable [♂ HE] / [♀ SHE] / [👥 DUET] pills on every lyric line in the teleprompter editor allow instant manual reassignment with automatic saving.
• 1080p MP4 Video Produce with Burned Multi-Style Subtitles: Advanced SubStation Alpha (.ass) rendering engine burns exact singer colors directly into exported videos via FFmpeg.
• Continuous Pitch Performance Scoring: Overhauled scoring engine evaluates pitch accuracy and rhythm on 50ms hop windows across the full vocal take with cents-level vibrato tolerance (no hardcoded scores).
• AI Spectral Repair & Stem "Healing Brush": Interactive 2D STFT spectrogram viewer ($20\text{ Hz} - 20\text{ kHz}$) with click-and-drag marquee box selection and 3 surgical inpainting algorithms: Attenuate (-18dB), Ambient Fill (Wiener), and Harmonic Interpolation.
• Next-Gen Vocal Studio & Diatonic 3-Part Harmonizer: Generates discrete +3rd Diatonic, +5th Power, and -8va Sub-Vocal stems locked to the detected song key and chords, adding them directly into the DAW mixer as controllable faders.
• Formant-Locked Voice Character Morphing: Apply Female Bright, Male Warmth, or Vintage Radio profiles without chipmunk distortion.
• Native Rust DSP Core (crates/wilsonix-dsp): SIMD RealFFT inpainting engine and GCC-PHAT transient phase alignment for zero-latency C-speed audio computation.
