Initially I was trying to connect my phone to play music into my p5 sketch using the audio-in. The factor that caused the project to collapse was that my browser didn't allow the option for choosing the mic I wanted. My process for building off of audio input was to figure out how to structure my input in a way that could help me think of a creative visual. I ended up creating a very simple game using the microphone volume.
The process of making this game was pretty simple but effective. I had the ball moving downwards an increasing speed, and in order to lift the ball the person has to make loud noises.
For me, I still want to somehow be able to play any song and have it play into my p5 sketch and make something off of that.
Reminds of this project, which includes screaming and smashing:
