ACE-Step Audio Inpaint
ACE-Step Audio Inpaint is a powerful music and audio editing model developed by WaveSpeedAI. It enables precise, intelligent modification of selected time ranges within an existing audio clip — perfect for fixing, remixing, or creatively reimagining tracks without re-generating the whole piece.
Key Features
- Precise Segment Editing: Modify only the section you want — define start and end times to edit exactly the range you need.
- Seamless Audio Blending: New content merges naturally with surrounding audio for smooth, undetectable transitions.
- Flexible Timing Control: Choose whether your start or end times are relative to the beginning or end of the track.
- Style & Lyric Adaptability: Add new instrumentation, effects, or lyrics while preserving the overall flow and tone.
- Controlled Variation: Adjust how much the regenerated section diverges from the original using seed and creative parameters.
Parameters
| Parameter | Description |
|---|---|
| audio* | Upload or link to an existing audio file (MP3 / WAV). |
| tags* | Define the target style or mood (e.g., lofi, hiphop, trap, chill). |
| start_time / end_time | Select the time range (in seconds) to edit. |
| start_time_relative_to / end_time_relative_to | Choose whether the range is relative to the start or end of the audio. |
| lyrics | (Optional) Add or replace lyrics for the edited section. |

Use Cases
- Repair or refine — Fix errors or off-beat moments in specific sections.
- Rewrite lyrics — Try new vocal phrasing or emotional tone.
- Remix segments — Replace or restyle a part of a song without altering the rest.
- Audio storytelling — Modify voiceovers or sound effects within a fixed-length clip.
Pricing
| Metric | Price |

- 3 min (180s) audio → 180 × $0.0002 = $0.036
