Audio Troubleshooting in Unreal Editor for Fortnite

How do I add custom audio?

The easiest way to add custom audio is by dragging your audio assets from your desktop into the Content Browser to get them into your project.

Use an Audio Player device and make sure to select the right audio file. Set the device to Auto Play, or trigger Play through User Options - Functions.

You can import audio up to 300 seconds long. You must own the copyright for any audio you import or it will fail content validation and/or be flagged. Your imported audio is also expected to follow our Fortnite Developer Rules.

What audio formats are supported?

The supported formats are: WAV, AIF, OGG and FLAC.

How can I loop audio?

You can loop audio indefinitely by using the Looping setting of the Wave Player node in a sound cue. You can also add a looping node in a sound cue and set the number of times you want to loop.

See how it’s done in this video and follow the steps in the documentation to create a sound cue.
