GPU Based Audio Processing Platform with AI Audio Effects – Simon Schneider – ADCxGather 2024

https://audio.dev/ -- @audiodevcon​

GPU Based Audio Processing Platform with AI Audio Effects - Are GPUs ready for real-time processing in live sound engineering? - Simon Schneider - ADCxGather 2024
---

Parallelising real-time audio effects requires complex task management and synchronisation. GPUs are optimised for parallel processing while still retaining flexible scheduling comparable to a CPU. As a result, it combines the strengths of both DSPs and CPUs in a single device. In addition, recent trends advocate using AI audio processing algorithms, which work best on GPU architectures.

This thesis presents an implementation of an embedded GPU-based audio processing framework on an Nvidia Jetson hardware platform. It can combine neural network inference and other audio effects into signal graphs that process within periods as small as 32 frames (0.667ms).

The signal graph does not restrict the number and combination of parallel and serial audio effects as long as the real-time limit is met. Therefore, the framework has been tested on large numbers of parallel channels, as found in a mixing console, and complex routing options available in high-end audio effect processors, such as the Neural DSP Quad Cortex.

Launching GPU work using the CUDA graph API produces better stability and performance than was observed using the CUDA stream API in a 2017 study. Processing a signal graph that fully utilises the Jetson's resources by mimicking a 64-channel mixing console on a 128-frame (2.67ms) period has a higher than 99% success rate. However, occasional stalling on the GPU can produce worst-case execution times of up to 20ms, regardless of the loaded audio effects. As a result, the framework can not yet be classified as real-time capable.
Further study of the CUDA scheduler and improvements to the operating system and audio driver may be able to achieve real-time capability in the future.

Simon Schneider

Simon is a musician based in Winterthur. After completing his Bachelor's Degree in IT he realized that he could combine his passion for music and software engineering in audio development. As a result, he went on to complete a Master's Degree in Electrical Engineering to learn about signal processing and hardware programming. During this time he was working part-time in the ZHAW Institute of Embedded Systems. There he developed an audio effects processing platform on an Nvidia Jetson GPU as part of his Master Thesis.

His bandmates will say, that playing the guitar is just an excuse to justify all the money he spends on music-related gear. While this is not entirely untrue, Simon is the type of programmer who spends days automating or streamlining a repetitive process that takes minutes to complete manually.
As a result, automating guitar effect changes or building a wireless InEar monitoring rack for shorter live show setup and teardown times simply requires a lot of gear.

Furthermore, Simon has a flair for modular and customizable software architecture. Since audio gear often lacks both of these qualities, he endeavours to make them a primary focus in all his audio development projects.

Performance Implications of Frequency Domain Crossfading for Time-Varying FIR Filtering – iustin sandu – ADC 2024

Performance Implications of Frequency Domain Crossfading for Time-Varying FIR Filtering - iustin sandu - ADC 2024
---

A common strategy to avoid audible artifacts when exchanging impulse responses used for convolution with audio signals at runtime is to use a simple crossfade. This often requires more than double the amount of operations by filtering the input signal with both impulse responses separately (often in the frequency domain), and blending the resulting signals in the time-domain. If the crossfade was applied in the frequency domain, one IFFT operation could be eliminated, at the cost of two direct convolutions between the two signal spectra with the blending functions. Most of the time however, transforming each filtered signal separately back into the time domain before blending is still significantly faster than applying the blending function through convolution in the frequency domain. With a carefully chosen blending function, direct convolution of the spectra could be faster than the time-domain multiplication. We look at why and how this technique might work and the associated performance implications.

iustin sandu

I am a software engineer at d&b audiotechnik where I work on algorithm design, implementation and optimization. I get excited about clean architecture designs and I like to think that performance does not (always) have to sacrifice elegant architecture. I have an MSc in Audio Engineering and can play a few John Mayer songs on the acoustic guitar.
