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

An online tool that turns an ordinary recording into 8D audio: the sound moves around the listener instead of just hopping from the left earbud to the right one. The movement is computed by a binaural HRTF model — the same one that makes a source seem to be behind you, above you or below you. The path is visible on a 3D scene, and an “Original” button lets you compare the spatial version with the source instantly. Save the result as MP3, WAV, OGG or FLAC.

How to make 8D audio

Put headphones on: without them the effect is inaudible — the left and right channels blend in the air.

Load a song (MP3, WAV, OGG, FLAC, AAC, M4A). The file is read in the browser and playback starts straight away.

Pick a character — Gentle, Classic, Intense or Dreamy — then adjust turn, distance, height, width, room and bass if you want to.

Compare with the original in one click and press Download: the file is saved as MP3, WAV, OGG or FLAC.

Features

Real HRTF, not left-right panning

Most 8D converters swing the volume between channels with a low-frequency oscillator. This one drives the Web Audio PannerNode in HRTF mode: the signal is convolved with measured head-related impulse responses, so “behind”, “above” and “below” actually appear — directions panning cannot produce at all.

Six paths, or park the sound by hand

Circle, figure eight, spiral, orbit, free drift and pendulum. Or stop the movement and place the sound exactly where you want it — front, behind, left, right, above, below — by dragging the orb across the 3D scene.

One-button A/B against the original

The “Original” button switches to the untouched recording with no pause and no seeking — both run in sync. You hear what the effect actually added instead of guessing.

Six rooms and an adjustable width

Bedroom, concert hall, cathedral, cave, open air and bathroom — the impulse responses are synthesised in the browser. The Width slider keeps part of the original stereo image under the rotation so the music does not collapse into a narrow point.

The export matches what you heard

Saving runs through the same audio graph as the preview — just rendered offline, faster than real time. MP3, WAV, OGG and FLAC, processed in the browser through WebAssembly.

Frequently asked questions

What is 8D audio?

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 colour, and that difference is exactly what binaural processing reproduces.

How is this different from other 8D converters?

Most online converters simply swing the pan between the left and right channel with a low-frequency oscillator. That sound travels along the line between your ears and can never be behind you or above you. This tool uses HRTF — convolution with measured responses of a human head — so “behind” and “above” are genuinely audible. You can check it in five seconds: switch to “By hand” and park the sound behind you.

Why are headphones required?

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.

Why does the music sound narrower than the original?

A point source is narrow by definition: a single point in space cannot have a wide stereo image. That is what the Width slider is for — it mixes the original stereo back in underneath the moving point. Around 25–40% usually keeps both the movement and the body of the music. The Bass slider returns the low end that also thins out when a mix is collapsed to a point.

Does the downloaded file match what I hear?

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.

Which formats are supported?

Input: MP3, WAV, OGG, FLAC, AAC and M4A. The size ceiling adapts to your device’s memory and is shown in the upload zone. Output: MP3 (128/192/320 kbps), WAV (16-bit PCM), OGG and FLAC. The output is always two-channel — binaural audio in mono stops being binaural.

Can I publish a track made this way?

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.
