SyncMix - YTM Beatmatched Crossfader

Profesjonalny crossfader z inteligentnym dopasowywaniem beatów dla YouTube Music.

**Seamless Integration with YouTube Music UI** SyncMix injects elements directly into the YouTube Music web interface to make queue building effortless: * **⚡ MIX Button**: Injected next to every song on list views, albums, and search results. Click it to add the track to your SyncMix queue with a single click. * **⚡ MIX PLAYLIST Button**: Added directly to the playlist and album headers. Click it to instantly import the entire playlist into the SyncMix queue. **Set how every track in the queue starts & plays** Define a Global IN Time that applies to all tracks in the queue at once — every newly added song inherits this start point automatically. Need to fine-tune a specific song? Each track has its own independent IN start point and relative PLAY TIME limit. Adjust them easily using precise step buttons (±1s/±10s), direct text input, or quick reset buttons (↺) that restore global defaults. The timeline immediately highlights your scheduled play range in purple so you know exactly what is set to play. **Smooth, automatic crossfading** When a track reaches the end of its PLAY TIME (or its natural end), SyncMix automatically triggers a smooth crossfade to the next song in the queue. You can also hit the CROSSFADE button at any moment to trigger the transition manually. The crossfade duration is configurable in the queue header, and you can choose from four transition curves: Equal Power (Sin/Cos), Club Blend, Linear, or Natural (S-Curve) — each giving a different feel to the blend. **Two-deck live view** The extension panel shows both active decks at once: NOW PLAYING with live playback position, and the STANDBY (UP NEXT) deck already preloaded with the next track. Both decks display their IN start point and PLAY TIME limit on a miniature waveform timeline so you always know where each transition will happen. **Headphone monitoring (CUE – 3rd tab)** Open a third YouTube Music tab and assign it as the CUE output in the Audio Routing settings. You can route Deck A/B (main mix) to your speakers and the third tab to your headphones — letting you silently preview upcoming tracks while the current mix plays uninterrupted. **Optional BPM analysis & beat alignment** For advanced users: enable the optional local Python backend to unlock BPM analysis and beat phase alignment. When active, SyncMix reads the BPM of both tracks and aligns their beat grids at the moment of transition so the crossfade lands on the beat — without changing the playback speed. **Fully local, no account required** Everything runs directly in your browser. No audio is sent to external servers, no data is collected, no sign-in needed. **Key New Features:** * **PLAY TIME Limit**: Configure how many seconds to play a track starting from its IN point, instead of calculating absolute exit points. * **Visual Highlights**: The active playback range is colored purple on the timeline. * **Select-on-Focus**: One-click in any time/duration input field immediately highlights the whole text for quick replacement. * **Quick Reset (↺)**: Reset any track's cue points to the global default values with a single click. * **All Button**: Quickly clear a playback limit and play the song to the end. * **RECONNECT TABS**: Restart the memory state and rebind tabs with one click.
