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.
