- Add BarkEngine and ChatterboxEngine as new vocal synthesis backends, supporting neural TTS with verse-level synthesis for natural prosody - Enhance VocalProcessor with SSML support for Edge TTS, content-aware pitch/rate variation, and improved humanization (per-sentence jitter) - Add comprehensive tests for new engines and vocal processor features Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add llm_generator.py with Ollama-powered lyric generation (falls back to template generator when Ollama is unavailable) - Add prompts.py with mood-specific prompt templates for the LLM - Wire lyrics engine selection into pipeline and config defaults - Update config defaults for levels, swing, and velocity variation - Update pipeline to pass sentence texts for content-aware processing Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Rewrite drum patterns with hip-hop grid (16th-note resolution), ghost notes, and multiple variations per style for organic feel - Add 'triphop' pattern style with 16th-note hi-hats (~16 events/bar) matching Vegyn/Headache production density - Enhance arranger with per-bar pattern rotation, swing model on off-16th positions, per-instrument velocity variation and jitter - Make verse sections use config-driven drum style instead of hardcoded - Rework drum synthesis: warmer kick, tighter hi-hat, normalized clap - Fix tests for updated pattern API (list[dict] return type, durations) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add analyzer.py: extract sonic fingerprint from any audio file (BPM, 6-band frequency balance, spectral shape, dynamics, stereo, MFCCs) - Add comparator.py: side-by-side comparison with per-metric severity scores and weighted overall similarity (0-100%) - Add parameter_mapper.py: translate analysis deltas into actionable config parameter suggestions (e.g. "raise kick +3dB") - Add report.py: formatted terminal output matching quality.py style - Rewrite CLI with subparser support: 'mood-machine analyze <ref.wav> --compare <gen.wav> --suggest' while keeping backward compatibility - Add 39 tests using synthetic audio (sine, clicks, bandpass noise) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Calibrate synthesis and mixing against 'The Beginning of the End' (Headache, 2023) using the new analysis module. Similarity improved from 48% to 72%. Synthesis: - Add upper harmonics (4th, 5th partials) and octave-doubled layer to pad synth, pushing energy into 500Hz-2kHz mid-range band - Low-mid gap closed by 7.7dB, mid gap closed by 7.3dB Mixing: - Add Haas effect (1-2.5ms L/R delay) on hi-hat, clap, snare for stereo image from mono drum stems - Widen drum panning (hi-hat 0.12→0.20, clap counter-panned -0.10) - Add configurable stereo_widen_amount (was hardcoded at 0.6) - Add subtle master stereo widening in the bus chain Config: - Tune melancholic.yaml: BPM 75→70, triphop drums, raised pad/kick/ hihat/bass levels, pad_filter_cutoff 1400→1800, velocity 0.20→0.38 - Add spotdl and chatterbox as optional dependencies - Add reference_tracks/ to .gitignore Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
