Common questions about alien ambience

Can I loop the alien ambience?

None of these files is a checked seamless loop. For a long scene, crossfade two of them.

Is there a spaceship ambience?

Yes. Start with the Hollow Metallic Alien Ambience Drone files.

In code: GET https://sfxmint.com/api/v1/roles/alien returns a default alien ambience file with alternates, and the MCP tool get_role_sound does the same for coding assistants. No key needed.
