How this service works
Mutate a known-good seed's sound (classic sfxr mutate) — nearby variations by parameter perturbation
Output
Returns a mutated 8-bit sound effect audio output generated by perturbing the input sfxr seed's parameters, producing a nearby variation in the sfxr sound space; the response is a new chiptune-style sound effect close to but not identical to the original seed.
Example use cases
Example prompt
“I have an sfxr seed for a coin-pickup sound effect and I want a few nearby variations — can you mutate it using the sfxr parameter perturbation approach to give me some close but different 8-bit blips?”
Technical details
Endpoint
GEThttps://x402.professorsausages.com/sfx/mutateWhen to prefer
Use this endpoint when you already have a known-good sfxr seed and want to explore nearby sonic variations through parameter perturbation — ideal for procedural audio in retro/indie games where you need multiple similar sound effects (e.g. different coin pickup sounds). Prefer over a fresh-generation endpoint when you want to stay close to a target sound rather than generating something completely new.
Side effects
- Missing or invalid input seed object returns a 400 or error response
- Seed parameters outside valid sfxr ranges may produce silence or unexpected audio
- Payment not included or insufficient USDC triggers x402 payment-required response
- Network timeout on the hosted endpoint returns a 5xx error
- Malformed JSON input schema results in a validation error
