Game ambience & background loop generator
Wind, rain, water, forest, cave — seamless looping background beds.
River (seamless loop)
Howling wind
Rain & distant thunder
The prompt
"running river water over rocks"
MCP tool:
generate_ambiencegenerate_ambience({
prompt: "running river water over rocks",
duration_seconds: 8,
loop: true
})Build the atmosphere of a scene from a sentence — howling wind, rain with distant thunder, a running river, a crackling campfire. Ambient beds default to loop:true, so we crossfade the tail into the head and hand you a clip that repeats with no audible seam.
Drop it on a loop in Unity/Godot/your engine for continuous background ambience. The river clip below is a generated seamless loop.
