About this extension
NOW AVAILABLE ON FIREFOX

Unlock your mind's potential with the ultimate browser-based audio engine.

Binaural Extension is a beautiful, distraction-free audio synthesis tool designed to help you focus, create, meditate, or sleep. Unlike static YouTube videos or expensive subscriptions, this extension puts a professional-grade audio engine directly in your browser, offering three powerful ways to hack your flow state.

🚀 THREE WAYS TO USE:
  1. SOLO MODE: VISUAL BINAURAL GENERATOR Use the extension as a standalone focus tool. Our unique interface lets you "see" and "feel" your mental state.

🎛️ The "Puck" Interface: Forget complex knobs. Simply drag the glowing Puck to shift your brainwaves.

Vertical Drag: Adjust the Target Frequency from deep Delta (Sleep) to rapid Gamma (High Focus).

Horizontal Drag: Tune the Carrier Pitch to find your perfect comfort zone.

🧠 Joffpoff Protocol (528 Hz): One-click access to the "Miracle Tone." Instantly tunes the engine to a 528 Hz carrier with a 7.83 Hz (Schumann Resonance) target frequency for deep grounding and healing.

🔊 Atmosphere & Isochronic Tones: Layer Pink, White (NEW), Blue (NEW) or Brown noise to block distractions, or enable rhythmic isochronic pulses for intense entrainment without headphones.
  1. LAYER MODE: ENHANCE ANY MUSIC APP Turn your favorite music into a productivity superpower. This extension is designed to run seamlessly alongside Spotify, Apple Music, SoundCloud, and more.

Invisible Layering: Add a subtle Alpha or Theta wave underneath your lo-fi beats or classical playlists. The browser mixes the audio sources automatically.

Rhythmic Sync: Enable "Isochronic Mode" and drag the Puck to manually sync the pulse speed with the tempo (BPM) of the song you are listening to.
  1. RETUNE MODE: TRUE 432Hz CONVERSION (NEW!) Don't just layer over your music—transform it.

True Pitch-Shifting: Our new audio engine intercepts the stream from YouTube and YouTube Music and mathematically retunes it to 432 Hz in real-time.

No Slow-Motion: Unlike other extensions that just slow down the video, our granular engine shifts the pitch while maintaining the original tempo and video speed.

Visual Confirmation: A sleek notification confirms when the Retuner is active, ensuring your listening environment is perfectly aligned.

✨ WHY BINAURAL EXTENSION?

100% Free Forever: No subscriptions, no "Pro" tiers, no ads. Just pure audio.

Real-Time Synthesis: No large audio files to buffer. The sound is synthesized live by your CPU for perfect clarity.

Background Play: Our injection engine ensures the audio keeps playing while you browse other tabs or work in other windows.

Privacy First: We don't track your listening habits or sell your data.

Themes: Void and Studio included.

👉 PRESETS INCLUDED:

Deep: Theta waves for meditation.

Focus: Beta waves for productivity.

Create: Alpha waves for flow states.

Sleep: Delta waves for deep rest.

Astral: 6Hz Theta + Pink Noise.

Lucid: Gamma waves for high-level cognition.

Study: SMR (Sensory Motor Rhythm) waves for focused learning.

Chill: 10Hz Alpha waves for relaxed awareness.

HOW TO START:

Solo: Open the extension and drag the Puck to find your flow.

Layer: Open Spotify, hit play, then launch the extension to add your brainwave layer.

Retune: Open YouTube, click the "RETUNE" dropdown, and select "YouTube" to instantly shift the audio to 432 Hz.

Perfect for students, developers, and creatives looking for a study aid or focus timer. Whether you need deep sleep music, a meditation assistant, or a brown noise generator for coding, this extension provides the ultimate sonic environment.

Note: This extension requires an active tab to generate audio. If you are on a restricted browser page (like New Tab), use the "Launch Isolation Chamber" button included in the app.
