The producer-feedback round: stable note tracking, the NOTE pitch source with
Key lock and Follow bends, unsure-means-neutral fallbacks, Anvil's Enhance
mode, MAIN and ADVANCED pages, Ballast on Grid by default, and Crucible's
sure-note slice names with a song key.

Adds docs/pitch.md for the shared pitch source, updates every changed
plugin's README and changelog, the release table, the editor previews, the
website bullets, and the status in docs/ideas.md.

nvrl 01fd3241eb feat(ui): MAIN and ADVANCED pages, Anvil main page around Mode, Split and Sub level
Producers found the panels crowded: every control had the same weight. The
header now carries a MAIN / ADVANCED switch (common-ui header_paged). The
main page keeps the controls a first result needs; the advanced page shows
everything, as before.

- Anvil: Mode (Replace or Enhance), Split and Sub level, plus Octave, Ghost,
  Keep and Output. Kick lock, Dynamics, Drive, Glide, Phase, Gate and the
  pitch switches move to Advanced. The note readout says when the original
  sub plays because tracking is unsure.
- Lathe, Temper, Knurl, Planish, Braze: tracking and fine-tuning controls
  (Gate, Smooth, Snap, Harmonics, Push at, Floor, Bright, Normalize, band
  gains, Phase) move to Advanced. Lathe labels the octaves of the note in Hz
  on the harmonic axis.
- Forge passes the page to its module pages.
- Weld: the main page shows the level won back at full height, Mode,
  Response and Output; the phase plot, Sections, Low, High and Gate move to
  Advanced.
- editor-check renders the advanced pages with --advanced.

nvrl adfb2c0287 feat: stable note tracking, NOTE pitch source and unsure fallback
Producers found the tracked plugins jumpy: the shared tracker switched notes
after 10 ms and retuned every 5 ms, so growls and formant basses flickered
and every tracked plugin acted on wrong notes.

Shared tracker (common-dsp):
- A new note needs a steady read for 40 ms; an octave down 80 ms, an octave
  up 200 ms (an octave-up read still fits the note's period and counts as
  agreeing). Inside a note the tuning only moves past a 0.25 semitone
  deadband. Follow bends keeps the old fast behaviour as an option.
- A trust score turns the note unsure while reads disagree; Tracker::active
  and NoteState report it, and Fallback latches "step back" across note ends.
- Notes end when the window start stays below the gate's release level for
  20 ms, so short gaps between notes are seen without waiting for the gate.
- PitchSource replaces the old (midi, gate, glide) arguments: Audio, MIDI or
  Note mode (a set note, no detection), plus a key lock (minor, major, root
  only) that snaps reads to the key.
- stems.rs: synthetic stems (growls, wobble, reese, formant, 808 slide,
  layered drop, noise riser) and a score; examples/tracker_report scores the
  corpus or real WAV stems. On the corpus the old behaviour makes up to 28
  extra note starts per second; the stable default makes none.

Plugins:
- Anvil, Lathe, Temper, Knurl, Planish, Braze and Forge gain the NOTE pitch
  source, the key lock and Follow bends (shared common-params crate and a
  shared header switch in common-ui).
- Unsure tracking: Anvil brings the original sub back in place of the sine,
  Lathe passes the audio through, Knurl fades its texture out; Temper,
  Planish and Braze hold their last sure tuning. Readouts show the note only
  when it is sure.
- Anvil gains Mode: Replace or Enhance (keeps the original sub and adds the
  sine under it).
- Planish slides its band edges over 6 ms on a new note instead of snapping.
- Ballast defaults to Grid parts, which need no tracking.

- Anvil 0.3.0: Ghost harmonics, Phone listen, Kick lock and the offset
  audition. Anvil now has a Kick sidechain input.
- Weld 0.3.0: delay spread display.
- Braze 0.1.0: first release.
- Mark the released items in docs/ideas.md and add Braze to the release
  table.

nvrl a42bca0e92 style(weld): format the delay spread tests 2026-11-06 14:16:42 +01:00
nvrl d536e3127a feat(weld): show the alignment's delay spread
Weld's allpass sections add group delay between 500 Hz and 4 kHz, where
listeners hear it best. Liski et al. (2021) measured a threshold of about
0.64 ms for a positive group-delay peak on clicks. Weld now reports how much
its delay varies over that range and, above the threshold, suggests
comparing attacks in SUM and SUM DRY.

Common fits from Weld's own tests spread 0.82-1.03 ms, so the line is a
neutral note, not a warning: sustained bass hides much more than a click.

- Fit::group_delay (analytic, per section) and Fit::smear_ms in weld-core.
- Report::smear_ms, filled by the analyzer from the applied fit.
- Tests against the numeric phase slope and the analog 4Q/w0 peak.
- Display only; the audio path does not change.

The io.storyboard.* IDs were a leftover from Motif Storyboard and named
old functions (motif, sub-anchor, layer-align) instead of the products.
Every plugin now uses io.narl.bass-foundry.<product>, and IDs are frozen
from here on, even across renames.

Hosts see the new IDs as different plugins: delete the old .clap files,
rescan, and add the plugins again in existing projects. Rivet session
JSON and Patina parameter IDs are unchanged.

- Rivet 0.5.0, Patina 0.3.0; Anvil, Crucible, Lathe, Temper, Weld and
  Knurl 0.2.0.
- Docs, changelogs and the release table describe the change.
- Website: upgrade note in the Install section.

Weld hears the other bass layer through the sidechain and fits polarity
plus up to four RBJ allpass sections to the measured cross-spectrum, so
the layers sum instead of cancelling. No latency; the layer on its own
keeps its sound.

- Worker thread: Welch cross-spectrum and coherence, Nelder-Mead fit with
  1/f weighting, a per-band loss penalty and model selection by share of
  the achievable gain; GCC-PHAT lag detection flags a late layer.
- Audio thread: allocation-free chain with a 40 ms warm-up and 40 ms
  crossfade per new fit; mono blocks go to the worker through a lock-free
  queue.
- Follow / Learn / Hold; the fit is persisted and restored without a
  crossfade.
- Editor: per-band loss and recovery against a perfect alignment, phase
  before and after, recovered dB, time offset and status.
- Tests for flat magnitude, crossfade, fit targets, Follow hysteresis,
  Learn, silence, realtime allocation and the persisted fit in the host.

Set the CLAP vendor of all seven plugins to "Bass Foundry" and name the
combined preview ZIP bass-foundry-windows-x86_64.zip. CLAP IDs and saved
state stay unchanged.

Bring development.md and releases.md up to date with all seven products,
the shared crates, the test types, the steps to add a product and the
published releases. Add texture problems and seven texture plugin ideas
to ideas.md.

nvrl e3286f9094 feat(weld): add sidechain test build
Weld will phase-align a bass layer to another layer it hears through the
sidechain. This first build only checks that FL Studio delivers the
sidechain to a CLAP aux port: it passes the main layer through unchanged,
meters the sidechain and offers Layer/Sum/Sum dry listening. No latency.
