Complete checklist for submitting sound effects, music, and audio assets to Epic's Fab marketplace
Based on Fab Technical Requirements
Audio products MUST have a way for buyers to preview the sounds before purchase.
Audio products MUST include an audio preview URL in the Long Description.
Audio preview should accurately represent the quality and style of included files.
Buyers should be able to listen without creating accounts on third-party sites.
Technical requirements for audio files in Unreal Engine projects.
Audio files must be imported into the engine as .wav files.
Audio files must not contain unintended hitching, clicks, pops, or distortion.
Provide audio files in the highest quality possible.
Audio files in a pack should have consistent, normalized volume levels.
Looping audio should loop seamlessly without clicks or pops.
Remove excessive silence at start and end of files (keep intentional timing).
Content-only projects have specific folder requirements.
Remove Binaries, Build, Intermediate, Saved, and Plugins folders.
All assets in ONE folder under Content. No other files directly under Content.
Organize sounds by type, category, or usage.
Name files clearly to describe what they are.
All asset paths must be 140 characters or less.
Use only English letters, numbers, and underscores in names.
Fix all asset redirectors before submission.
Adding Sound Cues or MetaSounds increases product value and usability.
Pre-configured Sound Cues add value for users.
If including Cues, document what they do.
If providing attenuation, ensure distances are appropriate for sound type.
A demo map showing audio in context is helpful but not always required.
For ambient sounds or music, a demo map can showcase the audio in context.
If including a map, it must load without errors or consequential warnings.
Audio-only content has straightforward version support.
New products must support the latest version of Unreal Engine.
Maintain support for one of the three latest engine versions.
Marketing and metadata requirements for audio products.
All text must be in English with correct spelling and grammar.
Document exactly how many sounds and what types are included.
Include sample rate, bit depth, and file format information.
Use relevant tags for the type of audio content.
Disclose if generative AI was used to create the audio.
Ensure you have rights to distribute all audio content.
All audio must be original or properly licensed for redistribution.
If using third-party samples or tools, declare it.
Ensure all critical items (🚨) are checked before submitting your audio product!
