Running High Channel Count Audio Applications on Linux RT - Olivier Petit - ADC 2023

Linux-based computing platforms are extremely popular to implement audio processing in embedded systems, from low power consumer devices running on ARM processors to professional multichannel solutions requiring the power of x86 based chips.

In this talk we will explore the different features that the Linux kernel offers to control real time performance and ensure glitch-free audio processing. We will study examples from a commercially available and actively maintained product, including successes and failures.

Topics that we will look at include:

• Linux kernel Real-Time patch
• Controlling thread real time priority and CPU affinity
• Measuring performance
• Common pitfalls

Olivier Petit

After an MSc in Integrated Circuit design, I have joined the Creative Technologies department of L-Acoustics in 2018 as a C++ software engineer. I have been taking an active part in developing innovative technologies to bring immersive audio to live performances, striving to better connect the artists with their audiences. I love the challenge of deploying audio solutions at large scales with high sound quality and (of course) reliability. Making sure our products are as intuitive and easy to use is also a priority for me. Unlike most of my peers I don’t play any instrument, I love climbing though!

Recent Updates to MIDI 2.0 & the MIDI 2.0 APIs in Apple, Google, Linux & Microsoft Operating Systems – by Florian Bömers

https://audio.dev/ -- @audiodevcon​

Recent Updates to MIDI 2.0 and the newest MIDI 2.0 APIs in the Apple, Google, Linux and Microsoft operating systems - Florian Bömers - ADC23

Members of the MIDI Association will provide a high-level overview of the latest updates to MIDI 2.0 specifications and the brand new MIDI 2.0 APIs in the Apple, Google, Linux, and Microsoft operating systems.

There will be an overview of specifications being worked on, including the Piano, MPE, Orchestral Articulation, and Camera Control Profiles, and the Network Transport specifications all of which are nearing completion.

We will briefly explain the MIDI Association MIDI 2.0 logo licensing program.

Most importantly, we will explain how developers can get access to the MIDI 2.0 tools and open-source code that the MIDI Association and our members are making available to both MIDI Association members and the larger MIDI development community.
