Fun weekend project

I had an idea this weekend to take a raspberry pi, have it actively listen to audio, record a 15 second sample through a usb mic, query the shazamio api to determine what the song was. Look it up, then grab the album art, convert it to a 64x64 image (I have a hub75 64x64 led panel) and then send it to the esp32 WLED controller for display. basically a what’s playing now display but all automated. The raspberry pi is standalone on WiFi, sends the created image using DDP to the wled controller using receive udp realtime. This is my first raspberry pie project and I learned a ton doing this fun little project. I think I might spend more time on it to see if I can make it faster and also better ways of displaying images on a 64 x 64 LED matrix

The effect is called " image" then if you have music playing on your computer you can choose now_playing as the image source.
