Credits

This library is heavily inspired by audio-cutter

The encoder used is mp3-lame-encoder-js

Works better with an example !

Here is a more concrete example on how to use this library

function getMyMp3Cut(blob) {
	let cutter = new mp3cutter();

	cutter.cut(blob, 0, 30, function(cuttedBlob) {
		console.log("My blob has been cutted! ");
		console.log(cuttedBlob);
	});
}
