Writing Tags

var params = {
  path: 'path_to_music_file',
  tags: {
    title: 'New tag title',
    artist: 'New Artist',
    album: 'New album',
    track_number: '4/10'
  }
}

id3_reader.write(params, function(err, data) {
  
  console.log(err, data);

})

Buffers

id3_reader now supports buffers, to use a buffer when reading tags use it as follows:

id3_reader.read(buffer, function(err, data) {
  
  console.log(err, data);

})

Writing tags buffer usage is as follows:

var params = {
  path: buffer,
  save_path: 'path_to_save_buffer_to', // optional
  tags: {
    title: 'New tag title',
    artist: 'New Artist',
    album: 'New album',
    track_number: '4/10'
  }
}

id3_reader.write(params, function(err, data) {
  
  console.log(err, data);

})

The save_path parameter is optional and if it is not supplied the buffer will be returned with the new tags. If the save_path is supplied the module will write the buffer to the supplied location.
