Two things came up on the new tab. Floated and sized down, it spilled
its knobs out of its window, and sized up it left the window empty.
Auto-gain lifted far too much: it brought 0 dB back to 0 dB, which at
-40 dB, 4:1 and knee 6 is +28.1 dB, so a sound at -24 dB came out at
-6 dB. And as a knob from 0 to 1 it blended between makeup and
auto-gain, so at 1 the makeup knob did nothing.
Layout:
- The knobs stay on the bottom line, centred, with the help line
above them.
- The levels fill the height left above. The curve is a square at
their right, centred up and down. It grows with the tab from 180 to
360 px and takes no more than 40 % of its width (picturesLayout).
- A floated window cannot be sized below what its pane needs. A pane
says so in its minWidth and minHeight, and the Compressor's is every
knob and the smallest pictures. Other panes keep 320 x 200.
- A pane put into an open window that is too small grows the window.
Auto-gain, as decided in #378:
- A Compressor's auto-gain gives back what it takes from a sound at
-18 dB, so that one comes out as loud as it went in. At the numbers
above that is +14.6 dB.
- Auto-gain is a switch on the Compressor, the Limiter and the
Saturation alike, a setting and no longer an input. The makeup or
output is added on top of it instead of being blended with it.
- A project from before reads a number as on above 0. Nodes never
set keep their defaults: off on the Compressor, on on the other two.
- The tab shows the switch at the right of the knobs, with the dB it
gives below it. With it on, the curve has a line at -18 dB from the
curve up to the diagonal.
- Every level reading keeps the gain of its time. Before, the whole
picture was read by the current makeup, so after a change the
tinting of the last seconds was wrong or missing.
Findings:
- My first e2e run of the layout clicked Dock where it was before the
window was sized up, so the window stayed open and the next check
went red. The check reads the button again.
Tests:
- Gate (melektaus-atx): 282 files, 4344 tests (6 new)
- e2e 34 (melektaus-atx): ALL PASSED, 118 checks (2 new)
- Offline in Chrome: a sine at -18 dB through -24 dB and 4:1 came out
at -17.92 dB with auto-gain on and -22.42 dB with it off.
- Counter-checks: the curve set at the top instead of the middle, and
every reading read at a gain of 0, each fail exactly their test.
- Looked at the window in screenshots: at its least every knob and
the switch show. At 1280 x 797 the levels fill the height, the
curve is centred at the right and the knobs are at the bottom.

A Compressor had only its number rows in the node. Its numbers are
easier to set by feel on a dial, and what it does is easier to judge
when the level going in and the level going out are seen side by side.
- Knob is a new widget in the toolkit: a slider bent into a circle,
its name above and a number field below. A drag up or down turns
it, Shift a tenth as far, a notch of the wheel a fiftieth of the
turn, a double-click sets the default, the number takes a typed
value. A taper gives the low end more of the turn.
- The Compressor's tab opens on a double-click, one per node, like
the Parametric EQ's. It has a knob for each of the seven numbers,
greyed while its input is linked.
- Its curve shows level in to level out from -60 to 0 dB. The point
where it bends sets the threshold, the end of the curve sets the
ratio that ends there.
- Its levels show the last 4 s on both sides of the node. Where it
takes more than 0.5 dB away, the stretch below the level coming in
is tinted. The makeup is left out of that.
- The Compressor is tapped like the EQ. SpectrumTaps listens to more
than one node at once and reads the loudest sample of the last
25 ms on each side.
- The node tabs share one map in the editor (nodeTabs), so a third
kind needs no new plumbing.
Findings:
- CI task 614 for 23922ee was red on the memory check of the stream:
the tab's renderer grew by 94 MB with nothing decoded. Play mode
made garbage of its own and was read before a collection. Both
readings in play now come after one, and the check compares the
growth streamed with the growth decoded (3.7 MB against 59.8 MB).
- The ratio handle sat on the right edge of the picture, where a
widget's hit area ends. The curve is inset by the grab radius.
Tests:
- Gate (melektaus-atx): 282 files, 4338 tests (17 new)
- e2e 34 (melektaus-atx): ALL PASSED, 116 checks (6 new)
- Counter-checks: an inverted ratio search, stop() letting go of
every node and a drag without its least step each fail exactly
their test.
- Looked at the tab in a screenshot: a blip at -4.4 dB came out at
-16.7 dB, the gap tinted, the threshold line at -24.
