Hey Nick,

That problem is indeed solved. Thanks!

But I have two new questions:

  • You had a good proposal above about audio compression via webm, ... (which I hadn't thought about so I started struggling with mp3 in the past). But I see this in the current code:

    mediaRecorder = new MediaRecorder(stream,  {mimeType: 'audio/webm'});

    Does this mean you already use webm?
    But then I wouldn't expect to get WAV chunks? I'm lost ...

  • And it is not clear to me how this field works:

    I understand from the MediaRecorder documentation, that the timeslice is being used as the length of EACH chunk:

    But when I specify N seconds, then I get the audio only after N seconds in my Node-RED flow. And after N seconds the recording stops automatically. I would have expected to get every N seconds an audio chunk (N seconds long chunks), until I press the button to stop recording. Or am I mistaken?

Thanks again!
