Add option to get Sound Level in decibels (dB) #170

Closed microbit-carlos closed 2 weeks ago

microbit-carlos commented 6 months ago

CODAL has the option choose between 8-bit and dB for the LevelDetector. We had a couple of requests and it's already built in CODAL, so it'd be good to have it in the next beta.

API Options:

Adding an argument to microphone.sound_level(), possibly microphone.sound_level(db=True)?
Creating a new function like microphone.sound_level_db()
Change units via different method, e.g. microphone.set_sound_level_unit(microphone.SOUND_LEVEL_DB)
- This would be my least preferred option

My preference would be microphone.sound_level_db(). It's simple. And it makes it very clear what the units are.
