YouTube Pre-Count

Plays a precise pre-count before YouTube videos. Auto BPM Detection, Hybrid analysis & Multi-Tempo support for practice.

Do you practice instruments or dance with YouTube backing tracks? Stop rushing to catch the first beat. YouTube Pre-Count ensures you start on time, every time. This extension plays a metronome count-in before the video starts, helping you synchronize perfectly with the music. 🎵 Core Features: Custom Pre-Count: Set BPM and beats per bar, then hear a precise count-in before the video plays. Auto BPM Detection: Detect BPM and beat positions automatically from the video's audio, or combine with manual TAP for hybrid analysis. Smart Loop Practice: Loop specific measures for targeted practice with optional count-in modes (Off / 2-beat / Full bar / Backbeats). Playback Speed Control: Adjust YouTube's speed (1%–400%) directly from the extension. The metronome automatically syncs to the adjusted tempo. Multi-Tempo & Sections: Handle songs with tempo changes by adding multiple BPM markers. Manage sections via list view with quick navigation. 🎵 Additional Features: Rhythm Modes: 10+ subdivision patterns — Every Beat, Strong/Weak Beats, 8th, 16th, Triplet, Swing, and more. Metronome Control: Independent sound/visual toggles and separate volume control. Real-time Overlay: Displays current measure number and effective BPM while practicing. Precision Start: Set a start measure or define the exact first-beat time (offset) to skip intros. Auto-Save & Export: Settings are saved per video automatically. Export/import as JSON for backup and sharing. 🎹 Recommended For: • Musicians practicing with backing tracks or MR • Dancers who need a precise cue to start choreography • Music students counting measures while reading scores 🔒 Privacy: This extension runs entirely in your browser.
