mp3-split

Split audio (and video) files

Install

Make sure you have ffmpeg installed and added to your path then run:

npm install [-g] mp3-split

If you don't have ffmpeg installed, you can install this package which comes with a bundled ffmpeg, and mp3-split will automatically detect and use it.

npm install [-g] ffmpeg-binaries

CLI

mp3-split comes with a built in CLI tool. Type mp3-split -h to list all options and see an usage example. For input you can use either a YouTube link or a local file.

The template file format should be in the following format. For more info, checkout ffmpeg's duration syntax page.

[([hh:]mm:ss[.ms...])] My Music Name

A template file usually looks like this:

[00:00] eli filosov [ p h i l o ] - oneofone_rwrk

Library

You can also use mp3-split as a library. Ex:

let mp3Split = require('mp3-split');
let options = {input: 'myaudio.mp3', audios: ['[01:30] My audio']};
let split = mp3Split(options);
split.parse().then((sections) => {
  for (let section of sections) {
    console.log(section.name);      // filename
    console.log(section.start);     // section start
    console.log(section.end);       // section end
    console.log(section.trackName); // track name
  }
});

mp3-split emits the following events.

// emitted before splitting a file section
mp3Split.on('beforeSplit', (info) => console.log(info));
// emitted after splitting file
mp3Split.on('afterSplit', (parsedInfo) => console.log(parsedInfo));
// emitted when a video is found within the given url
mp3Split.on('url', (videoInfo) => console.log(videoInfo));
// emitted when the "sections" option is parsed and BEFORE splitting the file
mp3Split.on('data', (data) => console.log(data));
