Real-time Confessions in C++: The Most Common “Sins” in Real-Time Code - Fabian Renn-Giles - ADC 2023
This talk examines the most prevailing misconceptions and frequent errors encountered when audio developers handle real-time code in C++. With my background as a contractor in the audio industry, I’m often called in to help fix subtle bugs in, or review code with real-time constraints. Yet, I see (and have myself made) the same type of mistakes over and over again resulting from a few common misconceptions of real-time C++ code.This talk offers an in-depth analysis of each of these misconceptions, debunking them with compelling examples from the audio industry.
Ranging from the ignorance of C++'s data-safety rules altogether, to the overuse of std::atomic and misbeliefs about the forbidden usage of locks and exceptions in real-time code, this presentation navigates the landscape between the theoretical rules of the C++ standard and real-world practical realities. This talk is an essential guide for developers seeking to avoid common pitfalls and write more efficient, reliable real-time code.

Workshop: Dynamic Cast: Practical DSP & Audio Programming - Emma Fitzmaurice, Harriet Drury, Anna Wszeborowska and Alex Korach - ADC 2023
Dynamic Cast: Practical DSP and Audio Programming
We'll explore the concepts of Karplus Strong Synthesis. This is a physical modelling synthesis, aiming at modelling a plucked instrument such as a guitar. Included DSP will be noise generation, delay lines and filters. We'll also touch on MIDI messaging and polyphony.
We'll be using the Cmajor platform for the practical aspect of this workshop. Knowing Cmajor upfront is not a pre-requisite; we'll guide the participants through the implementation gently.
This will be a self-contained workshop aiming to be accessible to all levels of learning - all elements used in the practical part of the workshop will be thoroughly explained in the introduction.
Dynamic Cast - Who Are We?
Dynamic Cast is a peer-to-peer C++ study group, a safe space for underrepresented groups (women, LGBTQIA+, minority ethnic). The Dynamic Cast workshop at ADC is designed to create an entry point to the industry for newcomers, everyone is welcome.

Democratization of Audio Dev: How it Started, Where it's Going - Aurelius Prochazka
In 2018, I gave a keynote at the ADC Conference in London. In that keynote, I discussed how audio developers can benefit from opening development to all, and how to escape the errors of past and design for the future. What did I get wrong? Did I get anything right? In this talk I'll give an overview of where we are now and update where things might be going.
I'm Aurelius Prochazka, I am the founder of AudioKit, an open-source audio generation, processing, and analysis framework for the Apple ecosystem. I am a partner in AudioKitPro LLC, a company started to use the AudioKit framework to develop audio applications. Currently, AudioKit has delivered more synthesizer apps on iOS ever, including the most #1 charted music apps ever and the perennial global favorite, the free AudioKit Synth One.
In 2018 I traveled to London to give one of the keynotes for ADC in London. I have a Ph.D. from the California Institute of Technology in Computational Fluid Dynamics.

Processing Audio Post Production Deliverables at Scale with Microservice Architecture - Ryan Frias - ADCx SF
With the explosion of streaming services that operate on a global footprint, the audio mastering pipeline has ballooned to include as many as 765 unique language audio packages created from original, each of which needs to be quality checked, encoded and packaged for delivery. The process can take weeks and involves creative and technical teams working to make derivative versions which must preserve the original creative intent as much as possible. The "Coda" Automated Media Ecosystem is a new extensible software platform from Skywalker Sound that automates the creation of soundtrack versions and cuts the deliverable process down from weeks to faster-than real-time. The system has already been used on premium Disney+ releases such as The Mandalorian and Moon Knight.
By automating soundtrack mastering processing from the highest original source mix format (often the Dolby Atmos mix), the automatically derived versions can be created with the same fidelity and attention to detail as the original language, improving the experience for all consumers in international markets. As the process is automated without the possibility of human error, the need to QC each pass is reduced, resulting in better results for consumers and considerable time and cost savings for content owners.
The creation of this complex media pipeline ecosystem involved the integration of multiple programming languages, frameworks, environments and hardware systems for the full stack--from low-level digital signal processing, to high level scaffolds, such as a global service mesh.

Using Faust in JUCE Projects - Julius Smith - ADCx SF
Faust (Functional AUdio STream) is a domain-specific functional programming language for sound synthesis and audio processing (https://faustdoc.grame.fr). Faust development is routinely an order of magnitude faster to write and debug than C++, and the run-time performance is usually within a factor of two. Development is further facilitated by the large Faust Libraries collection of signal-processing functions (https://faustlibraries.grame.fr). Since Faust compiles to C++, it is natural to integrate C++ header files generated by the Faust compiler into a JUCE project or the like. A limitation encountered is that Faust's powerful pattern-matching facility requires its "macro arguments" to be bound at compile time, i.e., not signals or controller parameters. An example is the filter order in Faust's filter-design functions. When these arguments need to change at run time, it can make more sense to translate Faust to C++, so that the recursive pattern-matching in Faust is replaced by recursive C++ functions. Experience using ChatGPT-3.5 and ChatGPT-4 for this purpose and others will be summarized.

DDSP-VST: Neural Synthesis for All - Nikhil Bhanu & Wilson Zhao - ADCx SF
We present DDSP-VST, a cross-platform audio plugin for real-time neural audio synthesis built using TensorFlow Lite and JUCE. DDSP is the underlying ML research behind this project that lets you combine the interpretable structure of classical DSP elements such as filters, oscillators, reverberation etc. with the expressivity of deep learning. This technology enables us to transform a given audio signal into any musical instrument by extracting the pitch and loudness and using those features for synthesis. In this talk we will discuss the technical and UX challenges of building an audio plugin powered by machine learning and making it accessible to musicians and artists.

Test Strategies for Multi-Threaded Code - Ryan Avery - ADCx SF
Multi-threaded code can be complicated. Realtime multi-threaded code even more so. And testing that code? Too often we give up faster than we can say “integration test”. But by switching around your thinking and adopting a few key strategies, you can start to tame the complexity and gain back a little bit of confidence in your critical code.

Using & Implementing Differential Reference Counting in Realtime Audio Code - Palmer Hogen - ADCx SF
Safely sharing dynamic memory across threads – especially when some of those threads have strict time deadlines – is a tricky problem space; unfortunately this scenario appears in realtime audio code. Some threads may still be accessing old data, so algorithms need to carefully avoid deleting anything still in-use.
Many deferred-reclamation strategies have emerged to address this risk, but these techniques have a general tradeoff between ease-of-use and throughput; ideally we would like both!
This talk presents a variant of traditional reference counting, which offers improved throughput at the expense of a more limited API.

TX/RX Part 1: Workbenching Neural Audio Solutions - Kieran Coulter - ADCx SF
Deploying neural audio solutions to hardware requires a robust design/deploy build system, and usually requires minimizing compute and reducing algorithm latencies to realtime. In Part 1 of this 2-part talk series, we will examine various shortcuts for workbenching (open source) neural audio DSP solutions on the host system.
