GPU Acceleration in Acoustics and Audio Signal Processing

What is it about?

Acoustics and audio signal processing play a substantial role in our daily lives. Multimedia applications and valuable audio tools rely on this field for technological advancements. On the other hand, their efficiency depends on the capabilities of computing systems that provide the required computing resources. GPUs (Graphics Processing Units) were originally designed for graphics rendering, but they have transformed various fields by accelerating computationally intensive tasks with their parallel processing architecture. This survey explores the potential of GPUs in accelerating acoustics and audio signal processing tasks. A comprehensive overview is provided, and it is found that audio filtering, room acoustics, and sound synthesis are the foremost research fields benefiting from this massively parallel processing. Opportunities have been identified for further research in unexplored domains and established areas that require updates due to improved algorithms and new hardware technology. This survey can be useful for anyone looking for a background on the subject and wanting to understand which tools and applications have been explored and tested, and potential future directions.
