A system enables interactive multichannel auralization of highly reverberant spaces in real-time by performing synthesis and feedback cancellation using GPU-accelerated uniform partitioned convolution. This approach supports up to 120 output channels and 20-second filters, maintaining processing times below a 2.6 ms latency budget for immersive acoustic experiences.
Key insights
- Uniform partitioned convolution is highly effective for real-time, low-latency processing of very long filters when optimized for parallel execution on GPUs.
- Consolidating both synthesis and feedback cancellation computations on the GPU significantly reduces overall system latency by minimizing data transfers between CPU and GPU.
- Off-the-shelf GPU hardware can meet the stringent real-time latency requirements (few milliseconds) for complex, interactive multichannel auralization of highly reverberant environments.
