Parameter Selection Logic

  1. audioId and musicIndex matching priority:
    • If only audioId is provided: Match by audioId
    • If only musicIndex is provided: Match by index position
    • If both are provided: Try audioId first, fall back to musicIndex if not found

​
Developer Notes

  1. Timestamp values are in seconds
  2. Returned waveform data can be used for audio visualization
  3. For instrumental tracks (generated with instrumental=true), no lyrics data will be available
  4. Typical use case: Karaoke-style lyrics display in music player interfaces
