Spatialization is a technique that permits the audio engine to create a fully 3D soundfield on a stereo headset.
GenAudio's AstoundSound, a highly optimized collection of advanced DSP C/ C++ software available as a library or a plugin for augmenting real-time audio engines on Linux, OS X, Windows as well as Android and iOS, can make use of AMD TrueAudio. Wwise is available for Linux, OS X, Windows, PlayStation 4, Xbox One et al. There is an audio plug-in for Audiokinetic's Wwise (Wave Works Interactive Sound Engine) to off-load computation to the TrueAudio DSP(s). The video games Murdered: Soul Suspect, Star Citizen, Thief and Lichdom: Battlemage (uses CryEngine) can be configured to use AMD TrueAudio if present. Such dedicated audio processing horsepower is specifically for generating immersive soundscapes and saves CPU cycles that can be used for other game processing tasks such as AI and Physics.
Support for the AMD TrueAudio ASIC is contained in the Linux kernel device driver amdgpu.ĪMD TrueAudio enables dedicated digital signal processing (DSP). Support for True Audio Next was added to the beta Steam Application programming interface in February 2018. It also clarified that TrueAudio Next uses the GPU's ray-casting technology to do the audio computation, and can also reserve GCN compute units for lower latency. The TrueAudio Next SDK was released as open source through AMD's GPUOpen suite in August 2016.
The move from a dedicated DSP to GPGPU breaks compatibility with the previous TrueAudio implementation. TrueAudio Next utilizes the GPU to simulate audio physics.
True Audio Next Ī new version of TrueAudio, TrueAudio Next, was released with the Radeon RX 400 series GPUs in 2016. On 18 March 2014, AnandTech evaluated AMD TrueAudio using the Thief video game. Any additional benefits of the TrueAudio DSPs, such as "better effects", have been severely criticized. The on- die TrueAudio DSPs provide a better "silicon area to computing power" ratio and "power consumption to computing power" ratio for audio processing than the CPU, effectively making it an audio acceleration unit. Independent software vendors (ISV), such as game developers, can use what is called a Wwise audio plugin to offload such computations to the TrueAudio DSPs. Audiokinetic claimed that it is up to 10%. ĪMD claimed that a few simple audio effects can use up to 14% of the CPU.
