My name is Donovan, and I love creating music. I’ve been writing, recording, and producing for years and have a lot of experience working with Logic Pro X. I know through first-hand experience how to reverse an audio file in the app. 

This post will show you how to reverse an audio file in Logic Pro X. I’ll walk you through all the steps to make this happen quickly and provide you with some other information along the way. 

Let’s dig in. 

Key Takeaways

  • You can find the Reverse feature in the Region section of the Track Inspector window. When you select this checkbox, whatever audio track or region you have selected will be reversed. 
  • Reversing an audio file can provide a cool effect to use in your projects, and you can reverse both long and short audio sections. 
  • Reversing an audio file is considered a destructive action, meaning it alters the original waveform of the track or region you use. You should always use a copy of the audio in case you want to revert to the original at some point. 

How to Reverse an Audio File in Logic Pro X

Reversing an audio file in Logic Pro X is a fun tool to use to add unique sounds or elements to your projects. This feature is easily accessible in the Region section of the Track Inspector, but I’ll show you exactly how to use it here.

Before getting started with the instructions on how to reverse an audio file, it’s important to know that you need to turn off Flex Time to reverse a file. If you have this feature enabled on a track, you won’t be able to reverse it. 

To disable Flex Time, simply turn off the Flex button by clicking it in the track window. The button will turn gray when it’s off, similar to the color of the rest of the track window. It will be blue if it’s turned on.  

Follow these steps to reverse an audio file in Logic Pro X. 

1. Open the Logic Pro X project with the audio file you want to reverse. 

2. Make sure that Flex Time is turned off. 

3. Click on the audio track or region you want to reverse. If you only want to reverse a region, or part of a track, you’ll want to trim it first. 

4. Press I to display the track inspector or click on the Inspector button from the main menu. 

5. Click on the arrow icon next to the Region setting a the top left of the screen when you have the inspector open. 

6. Click on the Reverse checkbox to reverse the audio file that you have selected. If you keep an eye on the waveform in the Track Inspector, you’ll see it change and reverse when you select this checkbox.

Quick Tip: You can change the audio file back to its original direction by unchecking the Reverse box. But remember that this is a destructive action on the file, so you won’t be able to change it back around unless you do it this way.  

How to Reverse a Vocal in Logic

You can reverse a vocal in Logic Pro X the same way you would reverse any other type of audio file. Follow the directions in the section above and ensure you have selected the vocal track when you open the Track Inspector. 

You can also reverse a single section of a vocal track if you trim it into a region. This is also known as cutting or splicing a track, and it’s a really easy thing to do by using the Trim tool from the toolbar in the main project window. 

Reversing vocals is a fun editing technique to explore. You can uncover some really weird and unique sounds that don’t sound like vocals at all, and it can provide you with some creative elements to work with in your projects. 

Reverse Apple Loops in Logic Pro X

You can also reverse any Apple Loops in Logic Pro X by following the same steps as reversing other audio tracks. You need to add the loop into an audio track first, but once you do that, the process is the same for reversing it. 

You can access Apple Loops by clicking on the Loops button at the top right of the main project window. The button looks like the loop of a roller coaster. You can then click and drag any loop you want to use into a track within your project. 

Logic Pro X Reverse Polarity

Logic Pro X also has a Reverse Polarity feature that is different than reversing an audio file. You might confuse the two if you are unfamiliar with the app or either of these functions. 

Reversing the polarity of an audio file is also known as inverting, and it can help fix out-of-phase issues that occur when recording. This is a more technical recording and engineering task that beginners probably won’t deal with often. 

To reverse the polarity of an audio file in Logic Pro X, you need to select Functions and Invert from the Audio File Editor menu bar. This will allow you to correct any phase cancellations or other related issues in your tracks.
