Does anyone remember Aureal 3D? Back in the late 90’s, Aureal brought true HRTFs (head related transfer functions) to desktop PC gaming. It was the first time you heard true 3D-posotional audio from 2 speakers. Then they were bought out by Creative Labs and the A3D API was essentially killed.
If you’ve been longing for true, 3D positional audio based on science, consider the technology reborn.
