19 properties · 2 required · 0 $defs| property | type | description | constraints |
|---|---|---|---|
| tags* | string | Comma-separated list of genre tags to control the style of the generated audio. | |
| audio_url* | string | URL of the audio file to be inpainted. | |
| minimum_guidance_scale | number | Minimum guidance scale for the generation after the decay. | 0 ≤ n ≤ 200 · default: 3 |
| guidance_interval | number | Guidance interval for the generation. 0.5 means only apply guidance in the middle steps (0.25 * infer_steps to 0.75 * infer_steps) | 0 ≤ n ≤ 1 · default: 0.5 |
| tag_guidance_scale | number | Tag guidance scale for the generation. | 0 ≤ n ≤ 10 · default: 5 |
| guidance_scale | number | Guidance scale for the generation. | 0 ≤ n ≤ 200 · default: 15 |
| scheduler | enum | Scheduler to use for the generation process. | euler | heun · default: "euler" |
| number_of_steps | integer | Number of steps to generate the audio. | 3 ≤ n ≤ 60 · default: 27 |
| granularity_scale | integer | Granularity scale for the generation process. Higher values can reduce artifacts. | -100 ≤ n ≤ 100 · default: 10 |
| guidance_type | enum | Type of CFG to use for the generation process. | cfg | apg | cfg_star · default: "apg" |
| variance | number | Variance for the inpainting process. Higher values can lead to more diverse results. | 0 ≤ n ≤ 1 · default: 0.5 |
| seed | integer | Random seed for reproducibility. If not provided, a random seed will be used. | nullable |
| lyrics | string | Lyrics to be sung in the audio. If not provided or if [inst] or [instrumental] is the content of this field, no lyrics will be sung. Use control structures like [verse], [chorus] and [bridge] to control the structure of the song. | default: "" |
| lyric_guidance_scale | number | Lyric guidance scale for the generation. | 0 ≤ n ≤ 10 · default: 1.5 |
| start_time | number | start time in seconds for the inpainting process. | 0 ≤ n ≤ 240 · default: 0 |
| start_time_relative_to | enum | Whether the start time is relative to the start or end of the audio. | start | end · default: "start" |
| guidance_interval_decay | number | Guidance interval decay for the generation. Guidance scale will decay from guidance_scale to min_guidance_scale in the interval. 0.0 means no decay. | 0 ≤ n ≤ 1 · default: 0 |
| end_time | number | end time in seconds for the inpainting process. | 0 ≤ n ≤ 240 · default: 30 |
| end_time_relative_to | enum | Whether the end time is relative to the start or end of the audio. | start | end · default: "start" |
