Microphone diagnostic
Checks every layer between your microphone and the transcriber, and reports what each one actually produced. Nothing here is uploaded.
Press Run, then talk continuously for about five seconds. Device labels only appear after permission is granted, so the list may fill in on the first run. Whatever you pick here is remembered and used by the other demos.
Live input level
Raw per-channel levels straight from the capture worklet, before any downmixing. This is the ground truth for whether audio is reaching the page.

Full transcriber path
Runs the real MicTranscriber with the same device, so we can tell a
capture problem apart from a transcription problem.
