Amd announces trueaudio next 1.2

AMD has released the TrueAudio Next 1.2 open source library version update. An update that has several notable performance and feature improvements, and reflects the improvements built into the version of TAN supported on Steam Audio.

First, the audio convolution algorithm includes a significant acceleration option called the "head-tail" partition method. This arrangement allows an audio thread to send a real-time audio buffer to the TAN convolution to receive a response much more quickly than with the conventional partitioned convolution.

Most of the computational overhead occurs in the background, between buffers to TAN, making this method very user friendly for parallel processing. At the same time, it provides a significant latency reduction and performance acceleration, since the calling audio thread is not blocked waiting for the entire convolution to be calculated.

Other optimizations have also been incorporated into the TAN Graphics Audio Acceleration Library to minimize memory usage, buffer transfer, and sync overhead. In particular, a significant performance improvement occurs when the IR kernel is dynamically updated while convolution is running.

The TAN GPU Utility Library supports AMD resource reservation, in which a configurable part of the GPU can be reserved for audio processing, in addition to normal GPU computing resources. Resource reservation protects audio and graphics queues, and compute resources lock on each other, allowing them to coexist on the GPU like never before.
