Parameter Selection Logic

  1. Use audioId to identify the specific track:
    • The audioId parameter is used to match the exact audio track
    • This parameter is required to retrieve lyrics for the correct track

​
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
