When checking microphone SoundEvents there is no way to "stop listening" #169

Open microbit-carlos opened 7 months ago

microbit-carlos commented 7 months ago

For example simply running microphone.current_event() turns on the microphone and there is no way to turn it off. Event with the new microphone.stop_recording().

@dpgeorge I was wondering if we should change microphone.stop_recording() to simply be microphone.stop() so that it could also apply for this use case where we might not want to listen for microphone events in the background?

We could add a separate microphone.stop_listening() method. Then the microphone will have two modes that it can independently start/run/stop: listening and recording.

I'm not sure how useful it is to have them separated. Is there ever a case where you always want to be listening for SoundEvents, even during recording, and when recording stops you want to keep listening? Maybe.

Also, if you use microphone.record_into(wait=True) and it stops automatically, or you use microphone.record() (which is blocking), does it implicitly turn off listening when it finishes recording?

Agreed, the user might want to control the microphone events and recording independently, so we should have two independent functions: stop_recording() and stop_listening()
