Splitting stereo files into mono in Logic Pro X

Depending on the type of projects that you work with, there are times when you’ll be sent stereo audio files. These could be stems from another studio, or they could be samples which you would like to manipulate. Logic will enable you to manipulate the individual channels, but finding out how is not clearly marked. As the old adage goes “It’s always in the last place you look”!


Pre-flight check


1. An empty logic project

2. A working audio interface to hear back the audio

3. A sample form the apple loops library

Once logic has done it’s preflight checks, it will open up the start screen to select a project. For the purposes of this tutorial, select an “EMPTY PROJECT”.

Select “LEFT” or “RIGHT” to listen to the corresponding channel. Once a side is selected, Logic will display two coloured dots. The side that is being played will be displayed by a light grey circle. The side that is not being displayed will display a dark grey circle.
