Audio
Create music, sound scenes, and voiceovers.
How do I generate audio?
Use Audio Studio to create music, a mixed Sound Scene, or a narrated Voiceover.
- Open Create and select Audio.
- Audio Studio contains Sound Scene and Voiceover, with Sound Scene selected by default when the feature is enabled.
- Music is also available for enabled accounts.
- Sound Scene turns a direct brief into one mixed audio track with speech, ambience, and sound effects; you can add compatible audio references and choose the requested duration.
- When Image is available, you can use one image instead of audio references to guide the scene.
- Switch to Voiceover to paste or write a script and choose a voice; Voiceover keeps character billing.
- The form shows the price before you submit.
- When processing completes, play or download the MP3 from Audio Studio or Library.
If a request is still being checked, keep the saved request and do not submit it again.
