ID3 Reader

A Node.JS ID3 tag reader for audio files, simple but thats what it does.
ID3 Reader now supports the writing of tags!!

ID3 Reader is available through an installation from npm
id3_reader

``
npm install id3_reader
`

#### Reading Tags
`
id3_reader.read(path_to_file, function(err, data) {

console.log(err, data);

})
`
The output from the above is as follows:
`
{
title: 'Nancy the Tavern Wench',
artist: 'Alestorm',
album: 'Captain Morgan\'s Revenge',
year: '2008',
track_number: '4/10',
genre: '137)Heavy Metal',
languages: 'eng',
rip_date: '2008-02-14',
ripping_tool: 'EAC',
release_type: 'Retail',
publisher: 'Napalm Records',
version: '2.3.0'
}
`

#### 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.

Special Thanks

A big thank you to richardadjogah for helping with the writing of tags, it helped to speed up the re-write of this module exponentially.
