Replace Section API FAQ
How precise can I be with section replacement timing?
Replace Section API supports 2 decimal precision for both infill_start_s and infill_end_s parameters. This means you can specify timing down to hundredths of a second (e.g., 15.25s to 23.78s) for extremely precise section editing and replacement.
Can I replace multiple sections in the same track?
Each API call replaces one continuous section defined by your start and end times. To replace multiple non-contiguous sections, you'll need to make separate API calls or chain multiple replacements, using the output of one as input for the next.
How do I ensure the replaced section matches the original style?
Use the 'tags' parameter to specify style characteristics that match your original track's genre, mood, and instrumentation. The AI analyzes surrounding audio context to create seamless transitions and maintain stylistic consistency automatically.
What happens to lyrics when I replace a section?
If you don't provide full_lyrics, the AI generates appropriate vocals that fit the musical context. To change specific lyrics, use the full_lyrics parameter with the complete lyrics (including unchanged portions), and the replaced section will feature your new lyrics while maintaining vocal style.
What are the limitations on section length I can replace?
You can replace sections of any length within your track, from fractions of a second to the majority of the song. However, very long replacement sections (over 60s) may be better suited for using the Generate Music API and manually combining segments.
