Build Status

Installation

Install via npm:

npm install musicmetadata

Supports

mp3 (1.1, 2.2, 2.3, 2.4), m4a(mp4), vorbis (ogg, flac)

API

var fs = require('fs'),
    musicmetadata = require('musicmetadata');

//create a new parser from a node ReadStream
var parser = new musicmetadata(fs.createReadStream('sample.mp3'));

//listen for the metadata event
parser.on('metadata', function(result) {
  console.log(result);
});

This will output the standard music metadata:

{ artist : 'Spor',
  album : 'Nightlife, Vol 5.',
  albumartist : [ 'Andy C', 'Spor' ],
  title : 'Stronger',
  year : '2010',
  track : { no : 1, of : 44 },
  disk : { no : 1, of : 2 },
  picture : [ { format : 'jpg', data : <Buffer> } ]
}

If you just want the artist - listen for the artist event:

parser.on('artist', function(result) {
  console.log(result);
});

You can also listen for custom metadata types that are not part of the standard metadata as defined above. For example if you wanted to read the TLEN frame from a id3v2.x file you can do this:

parser.on('TLEN', function(result) {
  console.log(result);
});

You can also listen for the 'done' event, this will be raised when parsing has finished or an error has occurred. This could be used to disconnect from the stream as soon as parsing has finished, saving bandwidth.

parser.on('done', function(err) {
  if (err) throw err;   
  stream.destroy();
});
