LLVM’s Real-Time Safety Revolution - Tools for Modern Audio Development - David Trevelyan & Chris Apple - ADC 2024

"Error: RealtimeSanitizer: call to malloc detected during execution of nonblocking function MyAudioCallback::process!"

"Warning (-Wfunction-effects): nonblocking function `MyAudioCallback::process` must not call blocking function `SketchyCall`"

Real-time programmers working on mission-critical audio, autonomous vehicle, and aerospace code are well-acquainted with the golden rule: “Thou shalt not call time-unbounded operations in your real-time thread.” Despite its importance, tools to enforce this rule have been non-existent—until now!

At ADC 2023, we presented RealtimeSanitizer; and now it's coming to mainline Clang. In the latest version of LLVM, RealtimeSanitizer (now RTSan) forms one of two new features that help uphold real-time guarantees by detecting calls to malloc, system calls, and other user-defined "unsafe" functions at runtime. We introduce the sanitizer, how it works, and how to use it. Next, we explore Clang's new Performance Constraints system, which can prevent blocking function calls from non-blocking functions at compile time. We will compare and contrast these methods and offer recommendations on how to integrate them into your codebase effectively.

By leveraging these new tools, you can ensure your real-time audio systems remain robust, reliable, and ready for any challenge.

David Trevelyan

I've been developing software for 15 years in academia, start-ups, big tech, and as an independent consultant. I completed a PhD in computational physics at Imperial College London before becoming an early engineer at Jukedeck, taking the company to acquisition by TikTok in 2019. At TikTok I spent 4 years as technical lead and architect of the company's foundational real-time audio and music processing SDK. Here I also designed and led the development of a number of fun new musical experiences, including mawf - an interactive AI timbre-transfer plugin instrument, which can be downloaded for free at https://mawf.io.

More recently, I invented RealtimeSanitizer which (thanks to my talented co-authors) is now integrated into the LLVM project. Most of my work now is as an independent audio software engineering consultant. My experience covers the full audio stack; high-level audio systems and multi-threaded architecture, real-time neural network inference, virtual instrument and engine development, digital and virtual-analogue signal processing, SIMD optimisation, and developer tooling. If I can help on your project, please get in touch!

Unit Testing in Cpp Like a Lazy Pro - Marcel Roth & Dino Pollano - ADC 2024
---

A lot of people have heard of unit testing. Many developers have added unit testing to their procedures. But not so many have tried test-driven development and understand how to build a rock solid test bed, that eventually allows you to throw your code away and replace it with whatever is more readable, more scalable, less resource intensive or better performing. The ‘lazy tester, lazy developer’ pattern is a fun way to explore this important topic.

Marcel Roth

Hello! I’m a Principal Software Engineer at Spitfire Audio with over 18 years of experience in DSP-focused companies across Germany, the Netherlands, and the UK. I studied Signal Processing at the Technical University of Berlin, where I completed my master’s thesis on recognizing musical instruments using a Hidden Markov Model.

Throughout my career, I’ve worked on a range of projects, including developing a parameterized convolution reverb at a small company called zplane.development. My journey in DSP has sparked a strong interest in test-driven development and other agile methodologies. But I’m still my happiest, when applying those skills to the audio buffer.

In my spare time, I play bass with the Cherry Pit Collective.

Dino Pollano

Fuelled by an obsession with guitars, synths, and music gear—and a budget that couldn’t quite keep up—I decided to learn how to make my own. This journey led me through a degree in Music and Audio Technology at Bournemouth University, then Sound and Music Computing at QMUL. Along the way, I had a stint building programmable guitar pedals (OWL) and eurorack modules for Rebel Technology and kicked off a career at Spitfire Audio, contributing to projects like LABS, BBC Symphony Orchestra, and AIR Convolution Reverb. My time at QMUL sparked an intense curiosity about DSP, leading to a brief internship at L-ISA/L-Acoustics. Rebel Technology introduced me to the wild world of DIY audio electronics, and to this day, I love working with soldering, small-signal electronics, and embedded systems.

How To Recreate/Restore a Full Game Boy Advance Soundtrack in High Quality – Vincent Dortel – ADC 2024

How To Recreate/Restore a Full Game Boy Advance Soundtrack in High Quality - Vincent Dortel - ADC 2024
---

A new subfield of video game music has recently emerged: some people call it music "restoration" (or recreation). It comes from the desire to preserve and share incredible soundtracks that were cursed by hardware limitations at the time they were composed. For instance, the Game Boy Advance was using sequenced music, associated with sound samples. Those sounds had to be heavily compressed so everything fits on a 8Mb cartridge, and the audio engine had limited processing power, low sample rate, cheap output speakers...

In this talk, I would like to detail how I restored the entirety of the soundtrack from the first two Golden Sun games (2001-2002), by tracking down the original hardware that was used to record the samples, extracting the midi sequences, carefully studying the subtleties for each instrument, applying modern mixing techniques, and even doing a bit of reverse engineering. The whole process was improved by creating python scripts and a custom VST in C++.

Crafting Better Generative Music in Games with Deep Learning - Kyle Worrall - ADC 2024
---

While the procedural generation of mechanical or visual content is widely adopted within the games industry, procedural music generation is utilised much less. There are a variety of reasons why procedural music has not seen similar levels of adoption, especially in the advent of large language models and Generative AI tools such as ChatGPT and Midjourney, where public opinion on machine learning for creative arts and music is particularly controversial. However, there are ethical, and responsible ways to empower composers and music designers, and even improve procedural music systems with machine and deep learning. The adoption of such technology, if used correctly, could reduce burnout and provide novel experiences for players.

In this talk, I will introduce the audience to the basics of machine learning, before presenting multiple peer reviewed studies from my PhD investigating how deep learning can be used to generate: additional layers for bespoke pre-composed game music; expressive performances of MIDI during game play; and outline ethical and responsible design considerations for AI powered game audio tools.

Digital Audio Workstation Architecture – Evaluation and Evolution – Ilias Bergström – ADC 2024

https://audio.dev/ -- @audiodevcon​

Digital Audio Workstation Architecture - Evaluation and Evolution - Ilias Bergström - ADC 2024
---

Last year’s “Architecture of Digital Audio Workstations” talk was a broad introduction, followed by an overview of two DAW applications’ architectures, and the decisions behind these. While it covered a great deal of ground, it also had to leave out several important topics.

This talk concentrates on two additional areas:

Evaluating Architecture
Evolving Architecture

We will discuss how requirements, constraints and quality attributes come into play when evaluating architectural decisions. This is needed throughout the design process - definitely while creating the initial architectural design, but equally importantly, continuously while maintaining the software.

The familiar saying bears repeating: “Software is finished when no-one uses it”. Throughout its lifetime, software is bound to evolve. The evolution will be driven by sometimes drastic alterations, making it inevitable that the architecture also changes.

After a general coverage of these two new topics, four concrete example cases will be discussed, connecting practice to theory:

1. On how changing requirements result in architectural changes, and introducing new design decisions, resulting in overall improvement.

2. How an existing architecture allowed adding a complex unpredicted feature, without altering the architecture.

3. How mistaken design choices can create “debt” in the codebase, and when/how to address this.

4. How adding a new feature requires designing around the existing architecture, and finding a good compromise between refactoring, and meeting the new requirements.

Inevitably there will be some overlap with last year’s talk, but that will be kept to a minimum. So while I encourage attendees to watch that talk first, this one will be created so that it can be followed regardless, for an audience with some knowledge of software architecture.

This subject area is vast, but I hope that this introductory coverage of the two additional important topics, of architecture evaluation and evolution, will help further build on the knowledge shared on this very central topic for our community!

Wait-Free Thread Synchronisation With the SeqLock – Timur Doumler – ADC 2024

https://audio.dev/ -- @audiodevcon​
---

Wait-Free Thread Synchronisation With the SeqLock - Timur Doumler - ADC 2024
---

When developing real-time audio processing applications in C++, the following problem arises almost inevitably: how can we share data between the real-time audio thread and the other threads (such as a GUI thread) in a way that is real-time safe? How can we synchronise reads and writes to C++ objects across threads, and manage the lifetime of these objects, while remaining wait-free on the real-time thread?

This talk is the second in a series of talks about thread synchronisation in a real-time context. In the first episode, given at ADC 2022, we focused on the case where the real-time thread needs to read a sufficiently large, persistent object that is simultaneously mutated on another thread. In this second episode, we focus on the reverse case: the real-time thread needs to write the value while remaining wait-free, and while other (non-real-time) threads are reading it.

The traditional solution for this problem in audio processing code today is double buffering. This strategy works well in certain cases, but like every algorithm it has certain tradeoffs. If we look beyond the audio industry, it turns out there is actually another strategy that has more favourable tradeoffs for some use cases: the SeqLock.

We describe the general idea of the SeqLock, discuss the different parts of the algorithm, and show a working reference implementation. It turns out that in order to implement a SeqLock portably and without introducing undefined behaviour, we need to reconcile the algorithm with the C++ memory model, which presents an interesting challenge. In order to make it work and be efficient, we need to be very careful with our use of memory fences, memory ordering, and atomic vs. non-atomic memory accesses. Along the way we will learn useful things about writing lock-free code in Standard C++.

Finally, we compare the tradeoffs between SeqLock and other approaches to this problem, offer some guidelines on which approach to use when, and present a proposal to add the SeqLock algorithm to the C++ Standard.

Guide to C++ ValueTrees – The Secret Weapon of JUCE – Brett g Porter – ADC 2024

https://audio.dev/ -- @audiodevcon​
---

Guide to C++ ValueTrees - The Secret Weapon of JUCE - Brett g Porter - ADC 2024
---

The JUCE website says "The ValueTree class is JUCE's secret weapon," and it's true. They give you:

- A really easy way to capture and pass around the entire state of your application's data at run time
- A rich mechanism to watch that data at a fine degree of granularity
- Trivially easy persistence of application state

...but at the cost (in comparison to using native POD or class/struct variables) of being:

- slower
- less convenient to use
- less type-safe, since all values are stored in the JUCE var variant type.

This talk will explore the new Cello library to abstract away the underlying API calls in favor of syntax that's more like working with POD data. The original goal was to be able to write code something like the below, but using ValueTrees as the backing data store:

struct MyStruct : public cello::Object
{
cello::Value＜int＞ x;
cello::Value＜float＞ y;
};

MyStruct demo;

// will be executed any time the value of X changes
demo.x.onPropertyChange = [&demo] ()
{
std::cout ＜＜ "x changed to " ＜＜demo.x ＜＜ "n";
}

// after executing this line, stdout should print: "x changed to 100"
demo.x = 100;
...and it's surprising how close to that we were able to get.

This project has a set of overlapping goals:

- make working with ValueTrees more like working with C++ objects and less like calling API functions
- add type-safety and type conversions without explicit use of VariantConverter objects
- reduce boilerplate wherever possible
- handle undo/redo management invisibly
- support validation of values when they are accessed
- explore the gray area between compile-time strong typing as in C++ and the kind of runtime dynamic typing that's possible using the ValueTree API
- explore the available methods of reactive programming enabled with this system
- build out new functionality that's implied by the capabilities of ValueTrees but perhaps not obvious, like:
- creating a kind of NoSQL database
- creating an in-process sync mechanism to make ValueTrees thread-safe
- creating a simple IPC implementation
- In general, add support for more complex use cases where the complexity can be hidden inside the framework.
