Not just 8D.
Way beyond it.
8D Rotation
Sound orbits around your head with interaural time delay and head-shadow filtering. The OG 8D effect.
Multi-band Surround
3-band frequency crossover with independent panning per band. Low stays centered, mids rotate, highs shimmer.
HRTF 3D Positioning
Chrome's native HRTF engine places sound in true 3D space. Orbit, figure-8, or drift paths with elevation control.
Binaural Beats
Subtle sine tones at different frequencies per ear. Focus (Beta 20Hz), Relax (Alpha 10Hz), Sleep (Delta 2Hz).

FAQ
Got questions?
A free Chrome extension that transforms YouTube audio into immersive 8D spatial sound in real-time. It uses the Web Audio API to process audio entirely in your browser — zero latency, zero data sent anywhere.
Yes. 8D spatial audio, surround simulation, HRTF 3D, and binaural beats all rely on separate signals to each ear. Any headphones or earbuds will work.
The core experience is 100% free forever — 8D rotation on YouTube, 8 presets with sub-variants, bass/clarity/reverb controls, and the real-time visualizer. Pro ($4.99 one-time) unlocks surround, 3D, binaural beats, and audio export.
No. Everything runs client-side in your browser. No analytics, no tracking, no account required. Your audio never leaves your device.
Slightly different frequencies played in each ear create a perceived “beat” your brain entrains to. Focus (Beta 20 Hz), Relax (Alpha 10 Hz), Sleep (Delta 2 Hz), Meditate (Theta 6 Hz).
