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

• ffmpeg with additional compilation flags --enable-libass --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

npm install audioconcat

var videoshow = require('audioconcat')

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

audioconcat(songs)
  .output('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)
  })

Take a look to the programmatic API for more details
