8D audio uses HRTF (Head-Related Transfer Function) binaural processing to create the illusion of sound moving around your head in three dimensions. Unlike simple stereo panning, HRTF simulates how sound waves interact with your head and ears, producing a realistic 3D listening experience through headphones.

Yes! 8D audio relies on binaural processing that only works with headphones or earbuds. Speakers can't reproduce the 3D spatial effect because both ears hear the same signal.

Circular moves sound in a smooth orbit around your head. Figure 8 creates a sweeping lemniscate path with vertical variation. Bounce swings left-right with front-back oscillation. Spiral dynamically changes radius while rotating. Random Drift combines multiple harmonic frequencies for organic, unpredictable motion.

Room types simulate different acoustic spaces using physically-modeled reverb. Small Room gives a tight, intimate feel. Medium Room is a balanced studio space. Concert Hall adds wide spaciousness. Cathedral produces long, epic tails. Outdoor creates open, airy ambience with minimal reflections.

Echo adds a warm feedback delay with a built-in lowpass filter that prevents harsh repetitions. It creates rhythmic repeats that naturally decay, adding depth and movement on top of the 3D panning effect. Higher values produce more prominent, longer-lasting echoes.
