Partials now predict their next frequency (`freq + velocity`) during the search phase, improving tracking for fast glissandos and vibrato. + - **Peak Prominence Pruning**: Added `prominence` parameter (default 1.0 dB) to filtering. Discards peaks that don't stand out sufficiently from their surrounding "valley floor," reducing noise. + - **Least-Squares Bezier Fitting**: Replaced heuristic 1/3-2/3 control point placement with a proper least-squares solver for cubic Bezier curves. Minimizes global error across the entire partial trajectory. + - **UI Update**: Wired up the "Prominence" input in `index.html` to pass the value to the extraction engine. + - **Documentation**: Updated `tools/mq_editor/README.md` with new parameters and algorithm details. + - **Files**: `tools/mq_editor/mq_extract.js`, `tools/mq_editor/index.html`, `tools/mq_editor/README.md` + ## Recently Completed (February 17, 2026) - [x] **MQ Spectral Editor Phase 2: JS Synthesizer** |
