How this service works
Replace a section of an audio file with AI-generated content.
Output
Returns an audio file (mp3 or wav) with the specified time region replaced by AI-generated content matching the provided prompt, seamlessly inpainted into the original audio.
Example use cases
Example prompt
“I have an audio file where the section between 30 and 60 seconds sounds bad — can you use Stability AI's audio inpainting to replace that segment with something that sounds like 'gentle ambient piano music', outputting it as a wav file using stable-audio-2.5 with 20 inference steps?”
Technical details
Endpoint
POSThttps://stability-ai.mpp.paywithlocus.com/stability-ai/audio-inpaint?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to replace or repair a specific time-bounded segment of an existing audio file using AI-generated content guided by a text prompt. Prefer this over full audio generation when you want to preserve the surrounding audio context and only modify a defined region. Ideal for fixing corrupted sections, replacing unwanted sounds, or creatively altering a portion of a recording without regenerating the whole file.
Side effects
- Missing required 'audio' field returns validation error
- Missing required 'prompt' field returns validation error
- Invalid model name results in error or fallback to default
- mask_start greater than mask_end causes invalid range error
- Unsupported audio file format may cause processing failure
- Very short or very long audio files may exceed processing limits
- Network timeout on large audio files during upload or processing
