A song could clip at the output without anyone noticing: a track and a
sound item at +12 dB each add up to +24 dB. The Song tab now shows how
loud each track and the whole song are, and a fixed limiter behind the
master keeps every sample under -1 dBFS in the editor and in the game.
- Each track head has a stereo meter up its right edge. The head is
190 px wide instead of 176.
- Out sits in the corner above the heads, with the loudest peak since
Play in dB. In the tab header it made the row too wide for a 1280 px
window, and the inspector lost its fields.
- The meters read AnalyserNodes beside the buses, one per side after a
channel splitter, so a peak panned hard is not halved. They are tapped
only while the song plays and its tab is shown.
- A clip lamp lights past 0 dBFS and stays through Stop. The next Play
or a click on the meter puts it out.
- The meter of a track that mute or solo keeps from being heard is grey.
- Music always plays through a bus of its own, with or without a sound
FX. That bus is what Out measures.
- The limiter is the one from #326 and needs the FX worklet. Until that
is loaded the master goes straight out.
- It is 5 ms late. latency() counts that in, so the playhead and the
alignment of a recorded take follow it.
- Unit tests build SoundLibrary without the limiter, as their wiring
checks follow every node of a voice.
- Out shows "-inf" while nothing was loud. The UI font has no infinity
sign, which the font test found.
Tests:
- Unit meter-view 8 new, sound-library 112 (2 new), 3 counter-tests
each red
- e2e 65 (melektaus-atx): ALL PASSED, 55 checks (3 new). Out wrote
+16.6 dB, behind the limiter the loudest sample was 0.8913
- Gate (melektaus-atx): 272 files, 4209 tests, one red in the font
test. Fixed after it, then the font and meter tests ran green.
