Embedded Software Development - A Wild Ride! - Matt Speed & Andy Normington - ADC 2023
Embedded software development (aka firmware) can be challenging, but it's incredibly rewarding. Sitting at the beating heart of all audio hardware products, it handles the UI, connects the physical and virtual, and transforms signals and sounds to bring the product to life.
Join us to hear about how it connects with the electronics, software development and QA worlds, and the fun you can have bringing hardware products to life!!

Matt Speed
Matt has worked at Novation for 8 years, helping to develop a range of synths and controllers. He loves DSP, mathematics and music, and has an unhealthy(?) passion for the 56k.
Andy Normington
I work with embedded software on new Focusrite and Novation products. Coming from a background in music and audio and having started my career more focused on electronics, I enjoy learning about the way the systems we develop work in the real world - it's always a little different to what I expect! I'm always on the lookout for ways to do things a little better than last time, which at work drives my interest in teams and tooling (and at home drives my ever-increasing stash of DIY tools and gadgets). I'm at ADC for the first time in 2023, and really looking forward to learning lots and meeting people.

Leveraging Pruning and Quantization for Efficient Real-Time Audio Applications - Dharanipathi Rathna Kumar - ADCx India 2024
In the constantly changing world of audio processing, the demand for real-time response and high-quality output is a relentless challenge, especially in the presence of computational constraints. The rapid growth in model complexity, especially in deep learning, has made it challenging to deploy complex models involving architectures such as TCN, LSTM, etc. on resource-constrained devices and/or to achieve fast inference speeds for tasks such as real-time audio effects, audio style transfer, and source separation. Model compression is vital to address these challenges, making it possible to retain high performance while using fewer computational resources. This talk delves deep into two paramount model compression techniques, namely pruning, and quantization, and explores their applicability in the context of audio applications.
Pruning is a method of eliminating redundant or less contributive weights from the model to reduce the computation resources required to run the network. We'll explore its variants, methodologies, and outcomes, and how it can drastically reduce computational complexity without significantly undermining model performance. Quantization is the process of reducing the precision of the weights, biases, and activations such that they consume less memory. By reducing the bit-width of model parameters, we can achieve sizeable savings in memory and computational power, making it indispensable for on-device audio applications for real-time audio contexts.
In this presentation, I elucidate that by adopting strategic weight pruning and parameter quantization, it is feasible to significantly enhance the efficiency of sophisticated audio models, paving the way for robust, real-time audio processing even in resource-constrained environments.

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.

RADSan: A Realtime-Safety Sanitizer - David Trevelyan & Ali Barker - ADC23
"ERROR: RealtimeSanitizer: call to malloc detected during execution of realtime function SketchyAlgorithm::process!"
We present RADSan, a realtime-safety sanitizer integrated into the LLVM project. Activated with a single argument to clang, RADSan allows developers to mark any function with a [[realtime]] attribute. At run time, realtime functions will error if RADSan detects activity that it knows is not realtime-safe.
Our talk will include:
• an introduction to sanitizers; what they do and how they work,
• an exploration of the realtime-safety testing problem space; what is (and what isn't) possible, and how this influenced RADSan's design,
• a deep-dive into the components of RADSan and how they work together
• a demonstration of how to use RADSan to mark functions as realtime and test a system's realtime safety
• an open discussion on how to best share this idea with the wider community

Generative Audio: Indian art, Computer music - George Panicker - ADCx India 2024
Generative music and audiovisuals have been the crux of the new media and music technology since time immemorial. The field has its legends and deities such as John Cage, Moog and Brian Eno. Yet the nature of procedural music and the "audio-visual" as an artform has an ancient history in the Indian subcontinent and its artistic foundations.
In this talk, New Media artist and Creative Technologist, George Panicker, will take the audience through a tour of the surprising connections between generative audio and Indian music and art theory, providing some interesting ideas for the future of indigenous instrumentation and music technology.

KEYNOTE: From NIME to NISE: Rethinking the Design and Evaluation of Musical Interfaces - Anna Xambó Sedó - ADC23
In this keynote talk, Anna will present her insights into designing and evaluating networked algorithmic spaces that support collaboration, participation, non-hierarchical structures and Do-it-yourself (DIY) practices for Sound and Music Computing (SMC) from a Human-Computer Interaction (HCI) perspective. She will dissect the term New Interfaces for Musical Expression (NIME) to propose instead the design and evaluation of 'NISEs', to accommodate the wider world of Sound-based music and art so that we can embrace other prototypes and systems that take into consideration other characteristics than 'new', 'interfaces/interactions', 'music' and 'expression'. We will look into a project that repurposes NIMEs as an educational tool; an AI-enhanced live-coding self-built environment that works as a customisable sampler of crowdsourced sounds; and a project related to creating natural NIMEs as interventions to the environment through sonic arts and sonification. The projects contribute to the vision of democratising SMC through the creation of technologies that can empower the community to solve real-world problems.

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.
