Notifications on sound input?

Hi All!

I have an RPi4 and the latest Hass.io build (thanks all!).

I’d like to add a sound sensor & recorder / playback component that allows me to record ambient audio, sense certain attributes (transitions from/to quiet/loud, volume, pitch, duration, etc.) and start recording the sound, then notify on my hassio iPhone app with a dialog to play the sound.

I suppose you could think of this like a video doorbell with sound only…maybe? Where movement or occupancy notifications are replaced by sound transition notifications.

Perhaps I could distribute remote mics around my space and do an automation: “if sound starts in living room and continues into kitchen, turn on kitchen light” or similar?

Any ideas would be helpful!

Cheers,

Ambi
