What is spatial (3D / 8D / binaural) audio?

Spatial audio uses HRTF (Head-Related Transfer Function) processing to make sound appear to come from any direction—left, right, front, or behind—when listening with headphones. "8D audio" popular on YouTube and TikTok is a style where music orbits around the listener, while ASMR creators use binaural placement such as whispering near the left ear. All tools on this page run entirely in your browser: your audio files are never uploaded to a server.

How to get started

First, run the headphone test to make sure your left and right channels are correct. Then try the 3D Audio Creator or 8D Audio Maker with your favorite track. For original ASMR content, combine the Spatial Timeline for clip-by-clip placement with reverb and noise reduction for a polished finish.
