time.sleep(5)Request parameters supported by the Stable Audio 2.0 API on EmpirioLabs. Defaults apply when a field is omitted.
| Parameter | Type | Default | Range / values | Description |
|---|---|---|---|---|
| prompt | string | - | - | What to generate. Be specific about genre, instruments, mood, and tempo. |
| mode | enum | text-to-audio | text-to-audio, audio-to-audio | text-to-audio: generate from prompt only. audio-to-audio: condition on a reference clip. |
| output_format | enum | mp3 | mp3, wav | Output media file format (mp3, wav, mp4, png, jpg, etc., depending on the endpoint). |
| duration | number | 190 | 1 to 190 | Seconds. Stability Audio 2.0 generates up to 3 minutes 10 seconds. |
| steps | number | 50 | 30 to 100 | Diffusion steps. More = higher fidelity, slower (and adds per-step credits). |
| cfg_scale | number | 7 | 1 to 25 | Classifier-free guidance. Higher = follows prompt more strictly. |
| strength | number | 1 | 0 to 1 | Audio-to-audio only. 0 = ignore reference, 1 = stay close to reference. |
| random_seed | boolean | true | - | If true, use a random seed each call. |
| seed | number | - | - | Reproducibility seed. Only used when random_seed=false. |
| audio_url | string | - | - | Reference audio URL for audio-to-audio mode. |
Generates up to 3 minutes of audio from text or via audio-to-audio transformation.
