8D audio from your own track — spatial sound in headphones

8D audio is an ordinary recording processed so that the source seems to move around the listener’s head. The “8” is marketing — there are no eight dimensions in it. The sense of movement comes from the sound reaching your left and right ear with different loudness, timing and color, and that difference is exactly what binaural processing reproduces.

Most online converters swing the image between the left and right channel with a low-frequency oscillator — their own pages say so. That sound travels along the line between your ears and can never end up behind you or above you. This tool uses HRTF: convolution with measured head-related responses. You can check it in eight seconds instead of taking it on trust — press “Hear an example”. The sound walks around you and labels every position: front, right, behind, left, above. If “behind” sounds behind, panning did not do it.

Binaural sound works because each ear receives its own signal. Headphones deliver the left channel to the left ear only and the right channel to the right ear only. From speakers both channels reach both ears and blend in the air, the difference between the ears is destroyed, and plain stereo is all that is left.

This used to be a fair complaint: a point source is narrow by definition. The track is now split into mid and sides — only the mid orbits, while the side component stays in place and holds the width. The Width slider controls that side signal and never touches the movement, so no setting of it can weaken the effect. Bass below 170 Hz stays put too: direction is not audible down there anyway, and orbiting the low end made the level pump. For more weight, use the Bass slider.

Yes. Preview and export build the same audio graph — panning, room, width and bass — from the same control values. The only difference is that saving renders that graph offline, faster than real time. If you stopped the rotation and placed the sound by hand, that exact position is what lands in the file.

Yes, and this is the one thing that decides whether it works at all. The effect is built from HRTF — a model of what each ear hears when a sound comes from a given direction — so it only exists while the two ears receive different signals. Speakers mix both channels in the room before they reach you, and the movement collapses into ordinary stereo. Anything worn on the head works: earbuds, over-ear, wired or not.

Processing does not change the copyright of the source recording. Your own material: publish freely. Someone else’s track stays theirs even in 8D — uploading it to a streaming service or monetising it needs the rights holder’s permission.
