8D Audio Converter

The 8D effect pans the music slowly left and right with reverb so it seems to move around you. Use headphones.

  4. Export and download.

What 8D audio really is

The effect called 8D audio is automatic panning: the sound is swept slowly from the left ear to the right and back, with a little reverb added so it seems to move through a space around your head. It is not true spatial or surround audio and nothing is added that was not in the recording. It works best on headphones, where each ear hears only its own side.

Settings

Time for one full sweep sets how long the sound takes to go left, right and back (1 to 30 seconds; 8 to 12 is the usual range). Depth sets how far it travels: 100 percent reaches the far side, lower values stay nearer the centre. Reverb amount adds space, and the movement can be smooth (sine) or evenly paced (triangle). A mono file becomes stereo.

Things to know

On speakers, or when the result is played back in mono, the movement turns into a change in level or disappears. Very fast sweeps are tiring to listen to. The exported file has the same length as the original plus the reverb tail.

Questions

Is this real 8D or spatial audio?

No. It is auto-panning plus reverb. Real spatial audio needs positional (binaural or object-based) processing, which this does not do.

Do I need headphones?

Yes, for the effect to work. On speakers both ears hear both sides.

What sweep time sounds best?

Eight to twelve seconds per sweep is common. Shorter sweeps feel dizzy; longer ones feel like a slow drift.

What does the effect do to a stereo song?

It acts like a moving balance control: the side away from the sweep is turned down and the near side keeps its level. At full depth the music is heard in one ear at the extremes. Lower the depth for a narrower sweep.
