NVIDIA Does a TrueAudio: RT Cores Also Compute Sound Ray-tracing
Positional audio, like Socialism, follows a cycle of glamorization and investment every few years. Back in 2011-12 when AMD maintained a relatively stronger position in the discrete GPU market, and held GPGPU superiority, it gave a lot of money to GenAudio and Tensilica to co-develop the TrueAudio technology, a GPU-accelerated positional audio DSP, which had a whopping four game title implementations, including and limited to "Thief," "Star Citizen," "Lichdom: Battlemage," and "Murdered: Soul Suspect." The TrueAudio Next DSP which debuted with "Polaris," introduced GPU-accelerated "audio ray-casting" technology, which assumes that audio waves interact differently with different surfaces, much like light; and hence positional audio could be made more realistic. There were a grand total of zero takers for TrueAudio Next. Riding on the presumed success of its RTX technology, NVIDIA wants to develop audio ray-tracing further.
A very curious sentence caught our eye in NVIDIA's micro-site for Turing. The description of RT cores reads that they are specialized components that "accelerate the computation of how light and sound travel in 3D environments at up to 10 Giga Rays per second." This is an ominous sign that NVIDIA is developing a full-blown positional audio programming model that's part of RTX, with an implementation through GameWorks. Such a technology, like TrueAudio Next, could improve positional audio realism by treating sound waves like light and tracing their paths from their origin (think speech from an NPC in a game), to the listener as the sound bounces off the various surfaces in the 3D scene. Real-time ray-tracing(-ish) has captured the entirety of imagination at NVIDIA marketing to the extent that it is allegedly willing to replace "GTX" with "RTX" in its GeForce GPU nomenclature. We don't mean to doomsay emerging technology, but 20 years of development in positional audio has shown that it's better left to game developers to create their own technology that sounds somewhat real; and that initiatives from makers of discrete sound cards (a device on the brink of extinction) and GPUs makers bore no fruit.

On the other hand, nvidia will probably bury this under gimpworks.
I'm blaming consoles of the current state of audio design. It's not worth it to create accurate positional audio if most of the players are using cheapo TV-speakers.
if I am not wrong, TrueAudio technology existed since HD 7800 series chip AMD just enabled it in R9 200 series
will Nvidia get into trouble by using that name again?
Don't fall for it bois

That could help with adoption, but given Amds and tencillicas grasp on consoles id wager true audio see's more use.
Everyone auto-bashing Nvidia, please stop for a moment and consider if the shoe were on the other foot. If AMD were releasing a raytracing GPU, you'd be singing endless high praises…
When it comes to consumer products, nvidia is a marketing company first like apple.
