    [News] AMD Develops TrueAudio Next to Compete with NVIDIA VRWorks Audio

    https://www.techpowerup.com/225113/a...-vrworks-audio

    AMD is developing a new GPU-accelerated audio pipeline to rival NVIDIA VRWorks Audio, the TrueAudio Next. The company will take this technology to the developers through its GPUOpen initiative. TrueAudio Next will bolster AMD's VR technologies portfolio, with a hardware-accelerated real-time "audio ray-tracing" pipeline that adds realism to sound in a 3D scene by computing how sound waves interact with the various objects in it. This is essentially what NVIDIA's VRWorks Audio does.

    At the silicon level, processing the interaction between sound and surfaces in a 3D scene takes significant amount of compute power. On AMD "Polaris" architecture GPUs, such as the Radeon RX 480, TrueAudio Next will take advantage of Compute Unit Reservation, a feature which allows apps to temporarily reserve a portion of the GPU's CUs. Real-time positional audio DSPs such as TrueAudio Next and VRWorks Audio are expected to gain prominence with VR games, as CPU-based procedural audio-pipelines can't keep up with the faster inputs of a VR HMD to changing the 3D scene, than conventional input devices. Accelerated audio pipelines are needed to ensure that the audio output is fluidly in-sync with the video output, to avoid affecting realism.
