Inpaint an Audio Segment

This endpoint allows users to replace a specific time segment of an audio clip using a textual prompt and optional lyrics. The inpainting operation blends new audio content into the selected range, guided by user-defined style and voice preferences.

To use the inpaint feature, upload a song and specify the lyrics you want to replace in the field 'lyrics_section_to_replace'. For best results, also provide the complete song lyrics in the lyrics.
