How to use Audacity to reverse audio in Windows -
Dіd you ever wonder how to plaу a song backwards? Do you want to know how to reνerse a song just to see what it would sound like? Perhaps you’re trying to play audio backwards to reveal messagеs hidden awaу in plain sight? Or maybe it’s time to chеck for yourself whether Pаul from The Beatles is really dead? Whatever the reаson, thіs tutorial illustrates how to reverѕe audio in Audacity on any сomputer or device with Windоws:
NOTE: This guide is created in Windows 11, but the steps are the same in Windows 10.
Download and install Audacity on your Windows PC or device
The first thing you need to do in order to play audio backwards is to get a program called Audacity. You can find it as a free download here.
You can use Audacity to reverse audio
Audacity is a free program designed to help you work with audio files and perform sound editing. It’s an open-source tool, so it’s completely free for anyone to use. There are no hidden costs, no advertisements, and no limitations whatsoever.
Download the latest version of Audacity compatible with your Windows device, and then install it. The installation part is very simple, so just click or tap Yes in the UAC window and follow the instructions in the setup wizard.
Install Audacity to reverse audio
Open the song you want to reverse in Audacity
After installing Audacity on your computer, launch it to see a welcome message. Close the “Welcome to Audacity!” window. If you don’t want to close the welcome message each time you open Audacity, first, check the option “Don’t show this again at startup.”
Get rid of the welcome window in Audacity
Open the File menu in the top-left corner, and then click or tap on Open.
TIP: Alternatively, you can also use the keyboard shortcut Ctrl + O.
Press Open from Audacity's File menu
Browse through your Windows computer or device to locate the song you want to reverse. When you find it, select it and click or tap on Open.
Open the Audio you want to play backwards
Audacity immediately loads the selected song, as seen below.
TIP: You can also drag and drop a song onto Audacity’s window in order to load it.

Now that your audio is loaded in Audacity, open the Select menu from the top-left corner, and then click or tap on All to select the entire song. Note that you can achieve the same result by pressing Ctrl + A on your keyboard.
To reverse an mp3, select it first

If you like the result, go to the next step of this tutorial to save your reversed song.
Save the reversed song
If you want to play the song you reversed with another media player without using Audacity, you should save the new audio file. Open the File menu again, go to Export, and then click or tap on the Export Audio option.
Choose to Export Audio
Audacity opens the Export Audio window that lets you select where to save the song on your computer, its name, format, and encoding. Choose the location and name as you see fit, but pay a bit more attention to the file type and encoding you want to use. The safest bet you can make is to go with the defaults: WAV (Microsoft) as type and “Signed 16 bit PCM” encoding. The result works on any Windows computer, no matter the version of the operating system, but, as a downside, you get a pretty large file. However, to use another file format, you might find that you must also install the appropriate audio codecs on your system. When you’re done, click or tap on the Save button.
How to save a reversed song
Before saving the result, Audacity lets you edit its metadata. Make any changes you want, and then click or tap on OK.
Finish saving the song you reversed
Audacity saves your song in its new reversed form at the location you specified.
What song did you reverse and why?
You can now use your favorite media player to play the resulting audio. If you want to listen to (more) messages hidden in popular songs, you can check out this List of backmasked messages.
