Here's the code that i have tried. the file got converted but is not in binary format.

if (err) throw err;

var encodedmp3 = new Buffer(data, 'binary').toString(2);
if(encodedmp3)

    console.log(encodedmp3);
}

//perform the encryption, then

fs.writeFileSync("music.sam", encodedmp3, function(err) {
    if(err) {

    }

   // console.log(encodedmp3);
}); 

Answer 1

The short answer is that you are looking for a JavaScript library for MP3s.

You are probably looking for the ffmpeg library. You can read a little tutorial on Medium . Alternately, you might look at the Howler.js library if you want a simple interface.
