Automator workflow for splitting large MP3s into 1hour chunks.
Split your MP3s into 1hour chunks with a single mouse-click and without quality loss directly within your macOS Finder.
This Automator workflow was created for allowing large MP3s to be uploaded into iTunes match. I love DJ sets and those often are too large to get uploaded due to Apple’s limits on iTunes match (max 200mb | 2hours per file).
mp3splt - Commandline utility to split MP3, OGG Vorbis and native FLAC files without decoding.
First, make sure mp3splt is installed. I would recommend using homebrew for that;
brew install mp3splt
Next, simply click on this workflow within your Finder to get it installed.
Navigate your Finder towards the MP3 you want to split.
Control click / Right click on the MP3 to get to the Services menu.
Chose the MP3 Split item.
Let it do its thing and get notified about progress. This should be fast - takes like 5 seconds for a 500mb MP3 on my machine. Once the notification disappears, you are all set.
The results will be a bunch of MP3s where the original name is extended by start and end time of the specific interval. Additionally, the MP3s will have a track-number within the ID3 information so you do not have to do that manually.
