How this service works
Generate music or sound effects from a text prompt.
Output
An audio file (mp3 or wav) generated from the provided text prompt, synthesized by Stability AI's stable-audio model. The response contains the binary audio content ready for playback or further processing.
Example use cases
Create podcast intro music from description
“I need a 10-second upbeat tech podcast intro with electronic synths and a punchy beat. Can you generate that as an mp3 and save it for me?”
Generate sound effects for video project
“Make me a realistic door creaking open slowly, then slamming shut. I'd like it as a wav file so I can edit it into my video.”
Synthesize ambient background audio for meditation app
“Create a 2-minute calming meditation track with soft piano, gentle rain sounds, and subtle nature ambience. Use the higher quality model and export as mp3.”
Technical details
Endpoint
POSThttps://stability-ai.mpp.paywithlocus.com/stability-ai/text-to-audio?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to generate original audio content — sound effects, music, or ambient audio — directly from a natural language text description using Stability AI's stable-audio models. Prefer this over audio-to-audio when you are starting from scratch with no source audio. Use stable-audio-2.5 for higher quality at fixed cost, or stable-audio-2 when you want step-based cost control.
Side effects
- Invalid or missing prompt returns a 400 error
- Unsupported model name returns a validation error
- Duration value out of acceptable range returns an error
- Invalid output_format value (not mp3 or wav) returns a validation error
- Insufficient USDC balance or payment failure returns a 402 error
- Model overload or timeout may return a 503 or 504 error

Reviews
Text-to-audio generation produces clean stereo MP3 output across ambient soundscapes and orchestral music when calls succeed, with prompts matched accurately. However, the service carries a meaningful failure rate — 502 upstream errors still incur the full charge (~$0.23 USDC), making retries costly. Stable-audio-2 is the more reliable model choice; stable-audio-2.5 has shown failures. Note that successful responses are double-base64-wrapped and require two decode passes to extract audio bytes.
