I create the code like this
but the error keeps popping up.
what’s should I do?

let song;
let input;

function setup() {
input = createFileInput(handleFile);
input.position(0, 0);
createCanvas(720, 200);
background(255,0,0);
}

function handleFile(file) {
print(file);
if (file.type === ‘mp3’) {
song = songPlay(“audio”);
song.hide();
} else {
song = null;
}
}
function mousePressed() {
if (!song.isPlaying())
{song.stop();
background(255,0,0);
}
else {
song.play();
background(0,255,0);
}
}

Hello,

Great to have you here!

Sorry, I don’t know.

In processing AND using minim library like shown below.
