adminandClaude Opus 5.5 3377524958 Zoom the Parametric EQ's dB with the wheel, saved on its node (#376)
game-maker / gate (push) Successful in 3m48s
game-maker / suite (push) Successful in 14m59s
Close moves of a few dB were hard to set and to see on a curve that
always spans -24 to +24 dB. The wheel on free space now zooms the dB
the curve shows, and the node's small curve shows the same range.

- The range is one of ±3, ±6, ±12, ±24 and ±48 dB, always the same
  either side of 0. Up zooms in.
- It is saved on the node as `range`, so it is back after loading.
  Like the game scale (#226) it is no undo step. EditorState gets
  `setNodeView` for such a setting of a node.
- The lines across the curve follow the range: every 1, 2, 3, 6 or
  12 dB. A handle whose gain lies beyond the range stays on the edge,
  in sight and in reach.
- The wheel over a handle still turns the band's Q. It no longer does
  so anywhere while a band is picked: after opening, a band nearly
  always is, and the zoom would be out of reach.
- `EqArea` carries the range, so the tab and the node map dB alike.
  The spectrum keeps its own scale.

Tests:
- Unit parametric-eq: 16 green, 5 new (range in compile and save,
  node picture, wheel steps, grid lines, handle on the edge)
- Counter-check: the node's picture without the saved range turns
  the new picture test red
- e2e 34 (melektaus-atx): ALL PASSED, 99 checks, 1 new
- Gate (melektaus-atx): CHECK EXIT 0, 275 files, 4252 tests

adminandClaude Opus 5.5 687377682c Draw the EQ's curve in its node and a spectrum behind it (#375, #374)
Both were asked for in #367 "for later". The node of a Parametric EQ
now shows its curve in small, and its tab shows what passes the node
while it is seen.

#375, the curve in the node:

- NodeDef has an optional `picture`: a height, and shapes made from
  the settings as plain point lists (guide, area, line). It is
  general, the Parametric EQ is its first user.
- NodeView draws it in a box below the rows, again only when the box
  or the settings change. A drag in the EQ tab changes them, so the
  node follows it live.
- Without a band the box stays, flat on its 0 dB line, so the node
  does not grow at the first band.
- The axes of the curve, `eqCurvePoints` and `fillShapes` move from
  editor/soundfx/eqView to core/soundfx/parametricEq. Tab and node
  draw the sum from the same function.

#374, the spectrum:

- A node marked `tapped` gets a `tap` stage in front of its own
  stages and one behind them when compiled, in a sound FX and in an
  instrument alike. Its id is asset and node, since a copied asset
  keeps its node ids.
- A tap is a gain of 1. SpectrumTaps (new, viewport/spectrum.ts)
  holds the tap of every voice and bus while it plays.
- While the EQ tab is seen, in the tab row or in a window, the taps
  of that node feed one analyser per side (8192 points). Nothing is
  made before a tap of the node plays, so no AudioContext is opened
  early.
- The tab draws both behind the curve, on a scale of 0 to -96 dBFS:
  the sound coming in faint and grey, the sound going on in the
  colour of a sound port. The analyser smooths it, and once the
  sound has gone the sum still hands it silence, so it falls away.
- Once the tab is not seen, Editor.tick lets the analysers go, like
  the meters of the Song tab.
- A tap does nothing to the sound, so `stats().last.stages` leaves it
  out, and a bypassed EQ keeps its taps.

Decided on my own:

- Every sound passing the node counts: Play of the sound FX tab, an
  instrument's keys, a song, a run. The issue proposed that.
- The spectrum has no labels of its own. Its scale is in the wiki.

Tests:

  Gate (melektaus-atx)     275 files, 4247 tests (11 new), EXIT 0
  e2e 34 (melektaus-atx)   ALL PASSED, 98 checks (2 new), twice

Counter-checks, each put back by copy and compared with cmp:

- The node's curve drawn without its bands: 2 unit tests fail.
- The spectrum without the loudest bin between two points: 1 fails.
- SpectrumTaps.stop leaving the taps linked: 1 fails.
- Taps that never feed the analyser: e2e 34 fails in exactly the
  spectrum check (frames 0). Run in the container only.

The screenshots of the second run were looked at: the blip as one
peak behind the curve, and the dip at 4 kHz in the node.

adminandClaude Opus 5.5 25084f8576 Refactoring round 10: split SoundLibrary, fold sound duplicates (#85)
game-maker / gate (push) Successful in 4m3s
game-maker / suite (push) Successful in 14m52s
Refactoring round 10 covers everything since round 9 (808e1ee): 110
commits with about 47 000 new lines, nearly all of them sound, sound
FX, instruments, patterns and songs. Behaviour is unchanged.

Duplicate code (jscpd over src, 50 tokens, TypeScript only, measured
on 808e1ee and here alike: 47 clones / 426 lines before, 33 / 245
after; round 9 itself ended at 22 / 160 by this count):

- PreviewParams (new, editor/soundfx) is the header's parameter bar
  of the Sound FX and the Instrument tab: values, defaults, fields
  and the voices a moved field reaches. Both tabs had it line for
  line.
- fxWorklet: an Effect base runs the bit crusher, phaser, flanger,
  limiter, LFO and bus shifter, a Source base the pitch player and
  the Chip. Start is the one wait for a voice's first sample, which
  four processors wrote out each.
- nodes/shared has checkPort, detachedPort, fxParamsPort and
  letRingPort. The Play and Stop nodes of sounds, notes, patterns and
  songs spelled each port out, up to five times.
- parameterValues builds both Sound FX parameters and Instrument
  parameters, which differed in name and text only.
- SetLoopCommand sets the ruler loop of a pattern or a song. It
  replaces SetPatternLoopCommand and SetSongLoopCommand.
- addLink in music/routing is the one rule for a link that both the
  song routing and the Master routing keep.
- eqCurves works out each band and their sum for the EQ tab, which
  did that in its drawing code. It replaces eqCurveDb, which only a
  test called.
- Smaller ones: the eight neighbour directions of a tile cell, and
  drawFloatingBox for the shadowed box of Popup and FloatWindow.
- Left on purpose: Play pattern and Play song stay two parallel node
  definitions, and the smaller clones under ten lines stay.

Architecture:

- SoundLibrary.ts goes from 2897 to 2188 lines. What a stage of a
  sound FX becomes as Web Audio nodes, and how the knobs of a playing
  voice move, is now viewport/fxNodes.ts. None of it keeps state of
  the library.

Dead code (TS language service, references per export and member):

- soundRefIds, LFO_SHAPE_INDEX, TREMOLO_ROWS, VIBRATO_ROWS and
  REVERB_ROWS had no reader. The four routing node defs are
  registered without an unused exported name.
- soundFileOf and portTypeOf were called by tests only. The tests
  now ask findSound and portOf, which the editor uses. DRY moves
  from src into the one test that uses it.
- 51 values used only in their own file lose their `export`. Types
  and the node catalogues stay exported.
- Kept on purpose: neighboursOf is the cell by cell reading the
  indexed neighboursIn is checked against, and PitchShifter.latency
  is the test's one view of how late the shifter is.

Comments and docs:

- Seven comments told history ("no longer", "any more", "as
  before", "of before #354"). Nine comment blocks ran far past the
  line width. Proof that this changed no code: the bundle was md5
  identical, and the touched tests and e2e modules were identical
  after esbuild.
- README: sound FX, instrument, pattern, song and bus in the asset
  list, the pages Instruments, Patterns and Songs, 1919 checks.
- Wiki: see its own commit.

Tests:

  Gate (melektaus-atx)    274 files, 4236 tests, CHECK EXIT 0
  e2e 34, 64, 65          ALL PASSED, 180 checks
  Unit, touched areas     16 files, 804 tests

No check was added, the e2e sum stays at 1919. Counter-checks, each
put back by copy and compared with cmp:

- addLink without the loop rule: 2 tests fail, one per routing.
- eqCurves with the sum of the last band only: 1 test fails.
- Start in the worklet never waiting: e2e 34 fails in exactly the
  four checks that hang on a voice's first sample (Flanger, Tremolo,
  Chip, a pitched note planned ahead).

adminandClaude Opus 5.5 1f13794b0c Shape a sound with a Parametric EQ and its own curve editor (#367)
game-maker / gate (push) Successful in 4m17s
game-maker / suite (push) Successful in 16m14s
A sound FX or an instrument had a 5-Band-EQ with fixed bands and a
Filter with one band. The Parametric EQ holds up to ten bands of any
type, and a double-click on the node opens an editor that draws the
curve they make together.

- The bands are a list on the node (`bands`): type, frequency, gain,
  Q and slope. A hand-edited project is held to the editor's ranges
  and to ten bands.
- Each band compiles to the existing `pass` stage, so the audio core
  is unchanged. A peak or a shelf at 0 dB is left out.
- The curve is worked out in `parametricEq.ts` with the biquad
  formulas of the Web Audio spec, so the editor draws what is heard.
- The editor is a window that floats over the editor without a
  backdrop, so the tab's Play stays usable. A double-click adds a
  peak, a drag moves a band, the wheel turns its Q, a right-click
  removes it. Fields below the curve set the picked band. It opens in
  the middle of the screen and moves by its title bar.
- A drag or a scrub writes the node as a preview and makes one undo
  step on release. The panels hear of the preview once a frame, and
  the window lays itself out only when one of its texts changes.
- The area under the curve is filled as one shape for each side of
  0 dB. As a single shape it crossed itself and came apart.
- The curve works out each band's coefficients once and adds the sum
  up from the bands. A drag took 295 ms of script time in a profile
  before and 64 ms after.

Decided on my own:
- Bands are added by a double-click, so a single click can let go of
  the picked band without adding one.
- The cuts are labelled "Low cut" and "High cut" as in an EQ, not
  "High-pass" and "Low-pass" as on the Filter.
- The bands have no input, so no parameter or Envelope moves them.

Tests:
- Unit parametric-eq (new) and soundfx: 69 green. Counter-probe with
  no stages emitted: the compile test red. Counter-probe with one
  fill shape: the fill test red.
- e2e 34 (melektaus-atx): ALL PASSED, 96 checks (3 new).
- Counter-probe e2e: no stages emitted, the playing check red.
- Gate (melektaus-atx): CHECK EXIT 0, 274 files, 4230 tests.
