Description
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. Smart Loop Practice: Loop specific measures for targeted practice with optional count-in modes (Off / 2-beat / Full bar / 2 & 4). Playback Speed Control: Adjust YouTube's playback speed (1%–400%) directly from the extension. The metronome automatically syncs to the adjusted tempo. Pitch Control: Shift audio pitch in semitones without affecting speed. Multi-Tempo & Sections: Handle songs with tempo changes by adding multiple BPM markers. Manage sections via a 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. BPM Detection Assistant: Analyzes the video's audio to suggest BPM and beat positions, assisting your setup process. Can be combined with manual TAP for hybrid analysis. Visual Offset Picker: Displays the audio waveform around the start point, letting you drag or scroll to fine-tune the offset with precision. Includes zoom, slow playback preview, and Test controls. Auto-Save & Export: Settings are automatically saved per video. 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. No personal data is collected or transmitted. Version 2.13.2 Updates: - Count-in Sound Control: Added a separate on/off toggle for count-in sound, independent from the metronome sound toggle - Pre-count-in Timing Fix: Fixed the timing offset when transitioning from the count-in to the first beat of the song Version 2.13.1 Updates: - Bug Fix: Sub-rhythm indicator lights no longer malfunction when changing settings during metronome playback Version 2.13 Updates: - Overlay Playback Controls: Control playback directly from the video overlay — restart, go to previous measure, pause/resume, and close — without opening the popup. - Skip Sections: Define regions to auto-skip (e.g., intros, outros) with seamless count-in transitions into the next section. - Minor Improvements & Bug Fixes - Pause/Resume: Play button now pauses and resumes from the current position instead of stopping and restarting. Restart and previous-measure buttons are always active. - #precount preview mode: entering via URL hash now shows settings without auto-playing - Overlay now shows speed percentage next to BPM when speed is not 100% - New rhythm pattern: 16th-note Shuffle (Swing / Shuffle 16th) - Pre-roll count-in: loop restarts now play a count-in before the loop point with a smooth fade-in transition - Restart button now restarts current measure first, then goes to previous on consecutive press - Bug Fix: test button now reflects the current picker position even before applying - Security: YouTube CSP headers are now only modified when pitch shift is active, keeping default browsing untouched Previous Versions (2.2–2.12): - v2.12: Visual Offset Picker - v2.11: Pitch Control - v2.10: Interactive Measure Timeline & Bookmarks - v2.9: Improved Layout - v2.8: BPM Detection Assistant - v2.7: Improved BPM Detection - v2.6: Smart Ad Detection, performance improvements, and bug fixes - v2.5: Adaptive Timing Engine with self-tuning sync and auto-calibration - v2.4: Auto-start reliability and stability improvements - v2.3: Speed Control (1%–400%), Tap button in popup/overlay, and new rhythm patterns - v2.2: Section management improvements and UI cleanup
