Sync YouTube choreography tempo and kick timing to music playing in another browser tab or in the room. Practice choreography to the music you actually want to hear. Dance Sync automatically adjusts a YouTube choreography video's playback speed and beat timing to match music playing in another browser tab or through a room speaker. Connect a browser music tab, open a YouTube choreography video, and Dance Sync analyzes both audio streams locally. It matches the choreography's tempo to your music and aligns quarter-note low-frequency beat timing. Features: • Automatically detects music and choreography tempo • Adjusts YouTube playback speed precisely • Aligns low-frequency kick timing, not just BPM • Holds an established tempo through musical breakdowns when the kick disappears • Works with supported browser-based music players and browser audio sources • Optional Room Speaker mode for external playback • Browser Music, Room Speaker, and Auto source selection • Supports switching songs and choreography videos during a session • Manual ±50 ms timing adjustment Privacy: Audio analysis happens locally on your computer. Dance Sync does not record, upload, save, sell, or share audio. Microphone access is optional and used only when the user enables Room Speaker or microphone fallback through Auto mode. Current limitation: Dance Sync matches tempo and quarter-note beat timing. It does not yet identify the musical “1,” 8-counts, or phrase boundaries.
