The previous "Test Microphone" meter only showed a raw 0-100% level bar — it
never ran the gate or any model, and its scale wasn't dBFS, so it couldn't tell
you which threshold to pick or let you hear the models solo. Replace it with a
real tester that reuses the shipped worklets (/public/element-call/denoise/) in
a main-app AudioContext, mirroring the call pipeline (source -> gate -> model).
- denoisePipeline.ts: shared loader for the RNNoise/Speex flat worklets and the
DTLN @workadventure helper, the noise gate, and a dBFS RMS meter helper.
- DenoiseTester.tsx:
- Live monitor: hear yourself through the selected model (+gate) in real time
(headphones) with In/Out dBFS meters and a threshold marker on the In meter
so the gate value is meaningful to calibrate.
- Record & compare: capture a short clip, then A/B the same audio Raw vs
RNNoise vs Speex vs DTLN.
- Wire it into the ML settings block; remove the old raw-only MicMeter. Use real
TDS tokens (--accent-*, --border-color, --bg-card) instead of the invented
--lt-* names + hardcoded hex the old meter used.
