A ready-to-run sample screen exercising MobAudioCapture, shipped so a generated app can kick the tires the moment the plugin is activated. Declared in the plugin manifest's :screens. Delete it (and the manifest entry) in a real app.

Tap Start and accept the system capture-consent dialog; the meter then shows the device output mix's live level (rms / peak dBFS) while any app plays audio, and silent when nothing does. Android only — on iOS every call reports unsupported.
