quicklrc-transcribe

Generate a time-synced lyrics or subtitle file from an audio or video URL using the QuickLRC API.

What it does

• Auto-transcribe — sends an audio/video URL and gets back a synced subtitle file
• Force-align — provide plain-text lyrics and the API snaps each line to the audio
• Word-level timestamps — karaoke-style output with per-word timing
• Smart sections — auto-detect [Verse 1], [Chorus], etc.
• Supports YouTube URLs directly

Auth
