EmoteBeat

Beat-sync Twitch, 7TV, BetterTTV, and FFZ-rendered emotes with local audio analysis and reactive chat effects.

EmoteBeat brings Twitch chat emotes to life by synchronizing their movement with the music playing on stream. It automatically detects the stream’s tempo, beat timing, accents, and frequency activity, then applies smooth beat-reactive effects to animated emotes, static emotes, and emojis. Features: • Automatic BPM and beat detection • Supports Twitch, 7TV, BetterTTV, and FFZ-rendered emotes • Works without requiring 7TV, BetterTTV, or FrankerFaceZ extensions • Speaker Pulse, Bounce, Wobble, Shake, Squash, and Pop + Tilt effects • Balanced, Bass Heavy, Vocal Gentle, and Festival reaction presets • Adjustable bass/kick, mids/vocal, and treble/snare sensitivity • Optional effects layered over animated emotes • Beat-reactive outward motion trails • Optional beat-synchronized Chat Edge Gradient • Effect intensity adjustable up to 300% • Automatic reset when switching Twitch channels • Compatible with Edge, Chrome, other Chromium browsers, and Firefox • Non-exclusive audio capture for improved compatibility with Shazam and similar tools All audio analysis happens locally inside your browser. EmoteBeat does not record or upload stream audio, chat messages, BPM history, or personal information. Open a Twitch stream, start playback, select EmoteBeat from the browser toolbar, and press Enable EmoteBeat.
