Honest question, as someone who's (probably) too young: What where these 3D sound cards and - just from the name - isn't that what Dolby Surround (etc) does?

- johnchristopher 5y agoIn the 90's I chalked it up to "surround or 5.1 marketing" but it might have been something else https://www.pcmag.com/encyclopedia/term/3d-audio https://www.pcmag.com/encyclopedia/term/3d-audio
- chha 5y agoYeah, there were several manufacturers who produced soundcards that basically offered two channels of sound, but where elements creating sound on-screen could be positioned as in a 3-dimensional world. I had a Packard Bell with an A3D[1] card, and I remember being fascinated by the demos they supplied.

- account42 5y agoJust with Creative's effects extensions, you can do virtual 3D sound in Software just fine now: https://www.pcgamingwiki.com/wiki/Glossary:Surround_sound#Binaural_sound:_HRTF https://www.pcgamingwiki.com/wiki/Glossary:Surround_sound#Bi... Next step would be to simulate and actual 3D sound environment but with GPGPU compute I don't think that needs dedicated hardware either.
