Audio
Upload an audio file and press play. The audio is routed through a 3D panner.
Loaded: (none)

Demo tone (optional)
Useful if you don’t have a file; spatializes a continuous oscillator.
Frequency
220 Hz
Level
-12 dB
Notes: The coordinate system follows the Web Audio API default listener orientation: +X right, +Y up, and the listener faces -Z. That means Z = -1 is in front of you; Z = +1 is behind.
3D Position
Move the sound source around the listener.

Quick tips:
- Click Enable 3D Audio first if your browser suspends audio until user gesture.
- If the effect is subtle, move the source closer (smaller distance) and keep volume moderate.
- HRTF is most convincing on headphones; speakers will blur the effect.
