Audio Analysis
Microphone Stream
Records a clip from your browser's microphone (Web Audio) and hands it to the flow as an audio file.
When to use it
Use it to try a voice flow on your own speech, to capture a short dictation, or to test a sound classifier without finding a recording first.

Worth knowing
- Press Record in the node's settings; the browser asks for the microphone the first time. The clip is saved in My files › Recordings.
- Every run uses the latest recording, so a scheduled run analyses the same clip until you record a new one.
