// Create a panner node for 3D positioning const panner = audioCtx.createPanner(); panner.panningModel = 'HRTF'; // most realistic 3D panner.distanceModel = 'inverse'; panner.refDistance = 1; panner.maxDistance = 10; panner.rolloffFactor = 1; 3d sound example

// Animate: move sound in a circle around listener let angle = 0; const radius = 2; function moveSound() const x = Math.cos(angle) * radius; const z = Math.sin(angle) * radius; panner.setPosition(x, 0, z); angle += 0.02; // rotation speed requestAnimationFrame(moveSound); moveSound(); // Stop after 10 seconds (optional) setTimeout(() =&gt;

// Start sound oscillator.start(); audioCtx.resume(); panner.panningModel = 'HRTF'
