Hello there!  
I’m currently working on a project that requires the micro:bit to detect specific frequencies, using makecode as my primary platform. I’m honestly really lost with the entire thing and how it would work. I want to implement CreateAI, but I’ve only explored the motion detection features, nothing sound related. If anyone has any ideas or where to start with this process, I’m completely open ears to anything.

Thank you!

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.
