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,

welcome to the forum!

Great to have you here!

Sorry, I don’t know.

In processing AND using _minim library_ like shown below.

Warm regards,
