Unit 9, the one that matters most for this creator. MASTER STRIP (top, nearest the preview): - one ladder fed by the MEASURED mix — `AudioMixer` now measures the buffer the encoder receives (`MasterLevel`, `MasterImbalanceDb`), so the master cannot show a source instead of the output - `-12.4 dB` readout, and ONE L/R flag that appears above a 6 dB gap instead of a second ladder - bitrate / FPS / dropped / duration from the existing health poll MONO OUTPUT: - `AudioFold.ToMono` averages each stereo pair into both channels, applied after the limiter and the sync delay, so the stream AND the recording get what was folded - `MonoOutput` is persisted (`Audio.MonoOutput`) and restored at startup: an accessibility switch that resets each session is an accessibility failure - one click in the strip, remembered forever Guard: AudioFoldTests (hard-left reaches the right at half amplitude, hard-right — the inaudible case — reaches the left, centred material keeps its level, mono buffers untouched) and MasterStripTests (the strip binds the measured mix + the switch, the store round-trips it, and the fold is the tested helper rather than new arithmetic). 33 audio tests green.
