KAI | Lyric Sync Console

Auto Sync API

Manual LRC Preview

1. Select Audio (.mp3)

2. Lyrics Source

Upload file Paste text

Use lyrics that actually match what is sung in the generated audio. If extracted or pasted lyrics differ from the vocal, alignment quality will drop and timestamps may look wrong.

3. Embed Mode

Overwrite lyrics tags SYLT only (keep plain lyrics)

`overwrite` updates USLT + TXXX:LYRICS with synced content. `sylt_only` writes only SYLT and preserves plain text tags.

4. Run

1. Select Audio (.mp3)

2. Paste Sync Data (LRC text)

3. Manual Alignment Tools

Editing Mode (no auto-play on line click, freeze timeline highlight)

Tip: click a lyric line in the preview to select it, then use Set/Nudge for precise manual timing.

Ready - select files and click Sync.
