audioconcat

Tiny node.js module to concat multiple audio files using ffmpeg

audioconcat provides a programmatic interface to do basically the same as calling ffmpeg via CLI like:

ffmpeg -i "concat:audio1.mp3|audio2.mp3" -acodec copy out.mp3

Requirements

• ffmpeg with additional compilation flags --enable-libmp3lame

You can download static builds of ffmpeg from here.

If you want to use audioconcat in Heroku, you could use the ffmpeg2 buildpack

Install

npm install audioconcat

Usage

var audioconcat = require('audioconcat')

var songs = [
  'beatles.mp3',
  'greenday.mp3',
  'u2.mp3'
]

audioconcat(songs)
  .concat('all.mp3')
  .on('start', function (command) {
    console.log('ffmpeg process started:', command)
  })
  .on('error', function (err, stdout, stderr) {
    console.error('Error:', err)
    console.error('ffmpeg stderr:', stderr)
  })
  .on('end', function (output) {
    console.error('Audio created in:', output)
  })
