Microphone Tester

A guided local workflow for mic testing: capture or upload audio, tune the visualizer, then export PNG/WebM/MP4 on-device.

Visualizer behavior and mode vocabulary are inspired by the open-source party-mode project by preziotte.

Start in Capture: pick your microphone and verify signal first.
