A Bitcrusher only said what it does in rows of numbers. How coarse
its steps and holds are could not be seen. Now the node is a device
of its own size. Its screen sends a sine through the node's own crush
and draws what comes out in cells, as tall as a step and as wide as a
hold, so the coarser the crush, the coarser the picture.
- CrusherPanel draws a 680x280 plate in bubblegum pink. Bits and rate
are large knobs, wet is small. Rate gives its low end more of the
turn, 8 kHz sits just past the middle.
- crushTrace runs a 440 Hz sine at 0 dBFS through Crusher at 48 kHz
and blends it as the worklet does. Where each hold starts comes from
Crusher too: a ramp through it at 16 bits takes a new value per hold.
- cellOf shapes a hold. From 5 px a step or hold gets a grid line and
a gap. Finer steps give a 2 px bar. A cell is never more than twice
as tall as wide, so 1 bit gives bars at -1, 0 and 1.
- The screen shows two periods, or 6 holds where the rate is low. The
sine going in is a grey ghost. Below wet 1 the heard line lies over
the cells.
- Above the screen a word for how crushed it is, CLEAN to BROKEN.
Under it the noise the bits leave and where the rate folds back.
- 16 lamps show the bits kept, the highest on the left. A CRUSH lamp
beside the name glows the more it crushes.
- COLUMNS_OF gives the Bitcrusher 4 columns in the presets.
- Hook __gm.bitcrusher.panel(id) for the sound FX and instrument
graphs.
Decided myself:
- The screen is still. Nothing on it moves, so tick() says false.
- How crushed counts whichever of bits or rate takes more, the rate in
octaves, times wet.
Found: at 8 kHz the first hold is 7 samples long, the rest 6. Six
sixths add up to just under 1 in Crusher. The worklet does the same,
so the screen shows what is heard.
Every sfxr effect preset ends in a Bitcrusher and gets 3 columns
wider. The Laser preset still fits whole on Fit.
Tests:
- Unit: crusher-view 13 tests (new). The screen matches Crusher with
its wet on three settings.
- Counter-test: without the wet in the blend the worklet test fails.
- e2e 34: ALL PASSED, 143 checks (1 new).
- Gate: CHECK EXIT 0, 292 files, 4484 tests.
