A Limiter only said what it does in rows of numbers. How much it took
away, and when, could not be seen at all, and a short sound is over
before any needle could show it. Now the node is a device of its own
size, and its screen catches the reduction from the moment a sound
starts and holds it once the sound ends.
- LimiterPanel draws a 720x280 plate of brushed brick. The threshold
knob is large, ceiling and release are small beside it, auto-gain is
a lever. A LIMIT lamp lights while it takes something away.
- The screen hangs the reduction down from the top, 0 to 24 dB by the
square root like the Compressor's meter. The level coming in runs
along the bottom, orange above the limit. Time runs from the start
of the sound over 1, 2, 4 or 8 s, and a longer sound rolls.
- ReductionCapture in limiterView holds the capture after 0.4 s of
silence, without the silence, until the next sound. It writes the
most taken away and when, and NOW or LASTED on the right.
- The Limiter is tapped now, like the Compressor. The face reads the
loudest sample since the last frame on both sides.
- SpectrumTaps.levels takes a lateBy. The side in front is read 5 ms
earlier, so a peak going in is met by what it became.
- limiterReduction leaves the auto-gain out and solves Wet's blend for
the limited part. Less than 0.2 dB counts as none.
- A capture is also held when the node leaves the picture. Changing a
knob or the lever leaves it as it is.
- Hook __gm.limiter.panel(id) for the sound FX and instrument graphs.
Decided myself:
- The capture stays held until the next sound, not for a fixed time.
- The screen has no wet knob, as the Compressor's has none.
- The Limiter's two taps cost two gains of 1 per voice. The analysers
only exist while the node is in the picture.
Measured on stein2: the seeded blip at -4.4 dBFS against -12 dB showed
7.56 dB. Three hits at 0, -8 and -2 dBFS showed 11.9 dB at the first.
In e2e 34 on melektaus-atx, -10.44 dBFS in against -20 dB showed
9.56 dB, the difference to the hundredth.
Tests:
- Unit: limiter-view 13 tests (new), spectrum 6 (1 new), soundfx 67
with the Limiter's taps.
- Counter-test: without Wet's share in the formula the blend test
fails.
- e2e 34: ALL PASSED, 138 checks (1 new).
- Gate: CHECK EXIT 0, 290 files, 4445 tests.
