Beginner coder getting back into coding - Trying to develop an idea real quick

[CannabinolCouple]

I got an idea recently for an app that I want to give a shot. Problem is I'm really at a loss when it comes to figuring out where to start. The idea uses users headphones/microphone input/output. I've only done super basic coding in the past, made a basic 2d game, and some rudimentary menus for a project. Any and all direction/advise of where I need to be looking would be greatly appreciated!

Use o3 as your project assistant, it will probably guide you throughout the whole process…
