1. There is absolutely no way a Micro:bit could run CreateAI, unless you are not talking about the AI image generation thing. Maybe that was a typo?

2. You might be able to figure out what’s going on in this topic from a long time ago: [V2 microphone frequency detection - #2 by bsiever](https://forum.makecode.com/t/v2-microphone-frequency-detection/17143/2)  
But it’s not an extension, so you’ll need to be able to use javaScript and maybe c++ from what I can see.
