AMD reveals its TrueAudio Next SDK

AMD added the source code of two new SDKs to its GPUOpen website. This includes TrueAudio Next and version 1.3 of the Advanced Media Framework. The latter is a set of tools that open up the Video Coding Engine and Unified Video Decover hardware in AMD GPUs to developers.

TrueAudio Next on the other hand is a software-based solution that runs atop AMD's Radeon Rays ray-casting engine. Developers can use this to improve the realism of sound effects in virtual reality applications. On the surface, this looks similar to the NVIDIA VRWorks Audio toolkit.

Unlike the original TrueAudio block in some Radeons, TrueAudio Next runs in software, and it's built atop AMD's Radeon Rays ray-casting engine. Together, these programs could provide more accurate simulation of the way sound waves interact with physical spaces to deliver a better sense of immersion in VR applications. TrueAudio Next also takes advantage of the Compute Unit Reservation feature in AMD's Polaris GPUs to ensure that audio-processing tasks can be completed with the low latency that VR demands. If all this sounds familiar, Nvidia has a similar tool for developers in its VRWorks Audio toolkit, which uses the Optix ray-tracer to promise similar fidelity.
