Game Audio: G8 - New Techniques for Zero-Latency Convolution

Frederick Umminger, Sony Computer Entertainment America

Low latency in audio is critical for virtual reality applications. This creates a need for low-latency but highly efficient convolutions for HRIR and reverberation. Ordinary, FFT-accelerated block-based convolution requires increasing latency in order to lower the CPU load with larger FFT block sizes. In 1993, William Gardner proposed a method of using non-uniform block sizes to simultaneously attain low latency and high efficiency. In 2008, Jeffrey Hurchalla proposed another method to accomplish this goal. This talk introduces two recent techniques for performing efficient zero-latency convolution.
