App 2.43.3: sound check on the Logs tab

Browse Source 
One tap listens for 10 seconds with Android's audio analyser on the output
mix and reports the levels, to learn whether it hears Bluetooth, CarPlay and
radio before the Halloween pumpkin's light follows the music. Levels only, no
sound kept, no microphone. Heard a test tone on the emulator. Not tried on
the car.

- 2026-10-31 — App 2.43.3: **sound check** on the Logs tab (`SoundProbe`, `SoundLevels`), asked for before the Halloween pumpkin's light follows the music (owner: "make the light in the pumpkin react to the equalizer/sound of the music"). One tap: 10 seconds of levels from `Visualizer` on session 0 (peak, bass, mid, treble, rms), saved and sent like a recording; no sound kept, no microphone. New in the car build's manifest: RECORD_AUDIO and MODIFY_AUDIO_SETTINGS. Grounds for trying: Bluetooth played with `isMusicActive` true (28 October check), `libCarPlayPlatformAudio.so` uses AudioTrack and no direct PCM. Whether the analyser hears anything on the car is what this is to find out. Tested: unit tests, lint, emulator (silence says nothing was playing; a pulsing 110 Hz + 1 kHz test tone from another app is heard, peak 0.27–0.91, bass strongest, the tone kept playing, no prompt, no crash). Not tried on the car.

- 2026-10-31 — App 2.43.2: Halloween's teeth are triangles hanging from the grin's upper lip, each in the colour of the rib behind it (the right one was the darker orange on the lighter rib; owner: "the color on the right side is off"). Two screenshots redone. Tested: unit tests, lint, emulator with sample values (drawing in panel and full screen, regenerating in full screen) and with no data. Not tried on the car.
