Frequently Asked Questions
How does binaural 3D audio work in standard headphones?
Binaural audio uses Head-Related Transfer Functions (HRTF), which mathematically recreate the subtle
microsecond time delays and frequency filtering our ears and skull naturally use to perceive 3D sound.
Why is 3D spatial audio essential for gaming?
In games like CS:GO, Valorant, or Call of Duty, accurate spatial audio allows you to pinpoint opponent
footsteps and gunfire behind or above you before you see them.
Do I need expensive 7.1 headphones?
No! HRTF binaural audio works brilliantly on any high-quality stereo headphones without needing
proprietary USB virtual surround cards.
Why does sound from behind sound like it is in front?
Some listeners experience front-back confusion with generic HRTF profiles because ear shapes (pinnae)
differ between individuals.
