Audio Agent

Aura can generate sound effects, music, and ambient audio, then save them directly into your Unreal project. It can also create and configure MetaSound assets to add playback controls, randomization, and procedural behavior on top of any generated audio.

ℹ️ Make sure you're in Agent mode to use the Audio Agent.

💡 Audio generation can take a moment to process. Remember you can work in multiple chat threads at the same time!

Generating Audio

Just describe the sound you need and Aura will generate and import it into your project.

Examples

• "Make a grenade explosion sound."

• "Generate 4 different footstep sounds on gravel."

• "Create a 30-second ambient forest soundscape with birds and wind."

• "Generate a short upbeat music loop for a happy game."

Generated audio is automatically saved to your project. You can customize the save folder in Edit > Editor Preferences > Aura > File Settings > Audio Generation Save Folder.

MetaSound Creation

Aura can wrap generated (or existing) audio in a MetaSound asset with configurable playback controls — volume, pitch, randomization, looping, and more.

Examples

• "Wrap this sound in a MetaSound with volume and pitch controls."

• "I have 4 footstep sounds selected — create a MetaSound that randomly picks one on play."

• "Generate a 15-second music loop and build a MetaSound with volume and pitch controls."

💡 To use existing sounds with MetaSound, select them in the Content Browser or drag them into your chat as context before asking Aura to work with them.

Workflow Tips

• Audio generation length must be between 0.5 and 30 seconds. Any requested duration outside this range will automatically be clamped to the nearest min/max value.

• Be specific about length. Telling Aura "make a 30-second ambient track" gives better results than a vague description.

• Generate variations separately. Ask for multiple sounds in one request (e.g., "4 footstep variants") and Aura will create them as separate files rather than overwriting a single one.

• Build MetaSounds on top of generated audio in the same thread. Aura can reference sounds it just created without needing them dragged in as context.

Current Limitations

• UE 5.3: Currently not supported for sound generation.

• UE 5.4–5.6: Known issue — the Wave Player node may not properly assign the generated sound asset. Manual reassignment may be required.

• Procedural MetaSounds (no audio source, fully synthesized) are experimental and may not always produce working results.

• Complex MetaSound graphs with many nodes may occasionally have incorrect connections. Review the graph if playback doesn't behave as expected.

• Aura may take extra steps to figure out MetaSound structure before producing a result — this is normal.
