TASKS.md is now the index (status table, open items, research pointer). 33 files: 32 task files + 1 research facts file. The full take-saga narrative and all design decisions are preserved verbatim; the catalog makes the queue readable without opening every task body. Schema and AGENTS.md updated to reflect the new layout.

# TASK 7 — Meter scaling amplification (voice meter uses the full bar)
|
||
|
||
> Catalog: [`TASKS.md`](../TASKS.md) — status and requirements live here.
|
||
|
||
|
||
**Goal:** the mic (and game) meters feel light — speech peaks should peg into the red at maxed volume.
|
||
|
||
### Status: ✅ Done
|
||
|
||
1. ✅ `AudioLevelMeter.ToDisplay` now adds **+10 dB of input amplification** before the −60..0 dBFS → 0..1 log mapping (was raw dB): speech peaks (~0.2 RMS, −14 dBFS) read ~0.93 → red zone; normal speech (~0.05, −26 dBFS) ~0.73 → yellow; background noise ≤0.001 linear (−60 dBFS) still reads 0 (the meter never idles on it)
|
||
2. ✅ Unit tests updated to the new mapping + new `ToDisplay_Pushes_Speech_Peaks_Into_Red_At_Maxed_Volume` (0.2 → 0.92..0.95, 0.05 → 0.72..0.75)
|
||
|
||
### Design decisions
|
||
|
||
1. **Amplify at the mapping, not in the VM** — one knob (`ToDisplay`), shared by the mic bar and the game bar; the `× MicVolume` gain-on-noise behavior is untouched (raising the slider still moves ambient noise up the bar).
|
||
2. **+10 dB, not more** — louder boosts push quiet speech into the lower half and make the noise floor visible; +10 puts speech peaks solidly in red while idle stays at zero.
