README

karaoke-maker

Turn any song into a karaoke track, locally, with one command.

python scripts/karaoke.py "https://youtu.be/..."        # or a local mp3/flac/wav/m4a/mp4

You get a folder with:

karaoke.mp4 – 1080p video: title card, two-line lyrics with a word-by-word highlight sweep, countdown dots before long instrumental gaps, progress bar, blurred cover-art background
instrumental.mp3 – the song with the vocals removed
vocals.wav – the isolated vocal
lyrics.lrc – word-synced lyrics for karaoke apps and music players
lyrics.txt – the lyrics that were used, so you can correct them and re-run

How it works

Step	Tool	Time (RTX 5060 Ti, 4-min song)
Fetch	yt-dlp or your file → 44.1 kHz WAV	seconds
Separate	Demucs `htdemucs` → vocals + instrumental	5 s
Lyrics	LRCLIB lookup (free, keyless) → fallback: Whisper transcript	1 s
Timing	stable-ts Whisper `large-v3-turbo` on the isolated vocal, chunked along its own silences, then the real lyrics are matched word-by-word onto that timing	10 s
Render	ffmpeg + libass (`\kf` karaoke sweep), x264	60-90 s

Everything runs on your machine. Nothing is uploaded anywhere; the only network calls are the optional download of the song and a lyrics lookup by artist/title.

The hybrid lyric step is what makes the result sing-able: transcription alone mishears words and breaks lines like captions, and database lyrics alone have no timing. Matching one onto the other gives exact text with the songwriter's line breaks and Whisper's word timing. When the database has nothing (or has the studio version of a live cut, detected by du
