Music surround by left and right headphones is called 3D surround sound effect.

A3D is a new interactive 3D positioning sound effect technology developed by Aureal Semiconductor. Software (especially games) using this technology can output corresponding changes according to changes in interactive scenes and sound sources in the software. sound effects.

Produces extremely realistic 3D positioning sound effects that surround the listener, bringing a real listening experience, and all this can be achieved with just a pair of ordinary speakers or headphones.

Sound effect positioning:

On most 3D sound effects sound cards, the HRTF conversion algorithm is used to convert the sound effects in the game, misleading your brain into hearing where the sound comes from. Different places.

Games that support sound source positioning combine sounds with game objects, characters, or other sound sources. When these sounds change their positions in the game, the sound card will adjust based on the relative positions. to adjust the transmission of acoustic signals.
