FLAC Audio File Metadata parser

A simple streaming parser for retrieving metadata from an .flac file.

Install

npm install flac-parser

Use

The parser is simply a stream in objectMode, so you can pipe and binary data into it and it will spit out tag objects.

var FLAC = require('flac-parser')
  , stream = require('fs').createReadStream('./my-file.flac')

var parser = stream.pipe(new FLAC());

parser.on('data', function(tag){
    console.log(tag.type)  // => 'samplesInStream'
    console.log(tag.value) // => 443520
})
