YT Loop Station

YT Loop Station brings studio-quality looping to YouTube videos with precision A/B point control and seamless crossfade technology. Whether you're learning guitar solos, perfecting dance moves, or studying foreign languages, this extension gives you the power of a professional loop pedal right in your browser. Precision Looping • Set custom A/B loop points with millisecond accuracy • Fine-tune loop points with jog controls (±50ms increments) Professional Audio Controls • Tempo Control: 0.5x to 2.0x playback speed with pitch preservation • Volume Control: Independent volume adjustment (0-100%) • 5-Band EQ: Professional equalizer (60Hz, 250Hz, 1kHz, 4kHz, 16kHz) Smart Loop Manipulation • Double or halve loop length instantly • Jump to previous/next section • Visual LCD display shows A/B times and loop length • Drag-and-position interface for optimal workflow Built for Practice • Bookmark favorite loops with custom names • Auto-load bookmarks when revisiting videos • Real-time display feedback for all adjustments • Scale interface up 25% for better visibility 🎯 PERFECT FOR Musicians: Learn solos, riffs, and complex passages note-by-note Dancers: Perfect choreography with precise repetition Language Learners: Master pronunciation and listening comprehension Students: Review lectures and educational content efficiently DJs & Producers: Study mixing techniques and beatmatching 1. Click the extension icon on any YouTube video (not shorts) 2. Click the footswitch to set point A (loop start) 3. Click again to set point B (loop end) 4. Video automatically loops between A and B with seamless crossfade 5. Adjust tempo, volume, EQ, and pitch without stopping playback The interface looks and feels like a professional guitar loop pedal with an authentic LCD-style display, rotatable knobs, toggle switches, and a red metal chassis design. • Web Audio API for professional-grade sound quality • Manifest V3 for modern Chrome compatibility • Minimal permissions (activeTab only) • No data collection or external connections • Runs entirely client-side for privacy and speed • Open source on GitHub Latest version (2025.11.4) includes 21 comprehensive bug fixes: • Proper memory management and cleanup • Fixed event listener leaks • Enhanced error handling • Audio context autoplay policy support • Improved display showing A/B times simultaneously • Better performance and stability For Musicians: Slow down that impossible guitar solo to 0.7x speed, loop just the tricky part, and gradually increase tempo as you master it. The pitch preservation keeps everything in the correct key while you practice. For Dancers: Isolate the 8-count you're struggling with, loop it endlessly at slower speed, and perfect your moves before moving on. Use bookmarks to save different sections of the choreography. For Language Learners: Replay that native speaker's pronunciation 50 times at 0.8x speed until you've got it down perfectly. The tempo control makes it easier to catch every sound. For Students: Loop the critical part of a lecture, adjust the EQ to clarify the speaker's voice, bookmark it with notes, and return to it during exam prep. Loop Control: The A/B looping system uses Web Audio API crossfading to eliminate the clicks and gaps you hear with basic video looping. The 30ms crossfade creates truly seamless playback, just like professional hardware loopers. Tempo Without Pitch Change: Unlike YouTube's native speed controls, YT Loop Station preserves the original pitch when you change tempo. This means you can slow down music to 0.5x for detailed practice without everything sounding low and muddy. Professional EQ: The 5-band equalizer gives you surgical control over the frequency spectrum. Boost the bass to hear that kick drum pattern, cut the mids to isolate the guitar, or enhance the highs for clearer vocals. Each band ranges from -12dB to +12dB. Jog Controls: Fine-tune your loop points with ±50ms precision using the jog buttons. This is essential for catching the exact start of a musical phrase or the precise moment a dance move begins. Bookmarks: Save unlimited loop configurations with custom names. Each bookmark stores the A/B points, tempo, volume, pitch, and EQ settings. Great for practicing multiple sections or coming back to specific parts later. Visual Feedback: The LCD display shows: • Current A and B point times (MM:SS format) • Loop length • Temporary feedback for volume, tempo, EQ, and pitch adjustments (2 seconds) • Current playback status Inspired by professional guitar loop pedals, the interface features: • Authentic red metal chassis design • LCD-style digital display with LED glow effect • Rotatable volume and tempo knobs with smooth drag control • Toggle switches for jog, section, and length controls • Hamburger menu for advanced settings • Draggable positioning so it never blocks your video We've switched to date-based versioning (YYYY.M.D) for transparency.
