How this service works
Transform an existing audio file guided by a text prompt.
Output
Returns a transformed audio file (mp3 or wav) generated by the Stability AI stable-audio model, where the input audio has been restyled according to the text prompt with the specified transformation strength and inference steps.
Example use cases
Restyle guitar riff as synthwave
“I have a recorded guitar riff — can you transform it to sound like a retro synthwave track with pulsing electronic beats and neon vibes? Use a transformation strength of 0.7 and give me the output as an mp3.”
Convert podcast voice to radio broadcast
“Take this podcast audio clip and restyle it so it sounds like a polished 1940s radio broadcast with that warm, vintage announcer character. Use stable-audio with a high number of inference steps and output it as a wav file.”
Transform ambient sound to horror atmosphere
“I've got a simple rain and nature recording — please transform it into a tense, eerie horror atmosphere with dark undertones and unsettling ambient textures. Use a transformation strength of 0.85 and return it as a wav file.”

Endpoint
POSThttps://stability-ai.mpp.paywithlocus.com/stability-ai/audio-to-audio?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to restyle or transform an existing audio file guided by a natural language prompt, using Stability AI's stable-audio models. Prefer it over text-to-audio endpoints when you have a source audio file you want to preserve as a base and modify rather than generating audio from scratch.
