Overview of Granular Synthesis - Avrosh Kumar - ADC 2025
---

For most, granular synthesis is a mysterious yet versatile technique. While some may find it fathomable, it remains an inexhaustible tool that yields complex timbres, textures and rhythms. Although it has been around for decades, people have found new ways to use it doing real-time effects and sound design.

This talk will review its history, delve into intricate details of its implementations and applications in simple pitch-shifting and time-stretching algorithms. The talk will serve as a survey of topics related to granular synthesis and, hopefully, provide a comprehensive resource on the topic for people trying to use or build granular tools.

Working With the Garage Door Up - Letting Others Take a Look Before You’re Ready - Andy Normington - ADCx Gather 2025

This talk is about working in the open in your day-to-day in a development team. Sharing early - whether it’s a rough idea, a half-written doc, or a messy prototype - can lead to fast feedback from people you might not expect, useful conversations, and even collaborators. We know the value of sharing early versions of products with customers to get feedback: we should bring that same spirit to our day-to-day technical work, too.

Have you ever crafted a detailed answer to a teammate's question and then buried it in your chat history? Or kept some half-baked solution thoughts to yourself only to discover that someone else has spent ages getting to the same result? We’ll look at how to make your work-in-progress visible to others without causing confusion, and why it’s worth the risk of looking stupid!

Andy Normington

I work with embedded software on Focusrite and Novation products, and lead our team's approach to developer tooling. 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 tools, and at home drives my ever-increasing stash of DIY tools and gadgets.

Designing an Audio Live Coding Environment – Corné Driesprong – ADCx Gather 2025

ADCx Copenhagen - 28th April
ADC Bristol ​- 9th - 11th November

Designing an Audio Live Coding Environment - Corné Driesprong - ADCx Gather 2025

Live coding is the practice of using code as a medium for visual or (in this case) musical expression and performance in real time. Code represents a uniquely flexible way of expressing musical structures and ideas, unconstrained by the fixed architectures of GUI-based tools such as DAWs.

Over the past year, I’ve been developing a new live coding environment called ohm. In doing so I’ve encountered a number of interesting design questions that I’ll discuss in this talk, such as:

- What live coding languages and audio programming DSLs exist, and what are their respective strengths and limitations, including the trade-offs between visual and textual programming
- How to design a domain-specific language (DSL) that describes audio graphs and musical structures in an expressive yet readable way
- How different programming paradigms—imperative, functional, declarative, and dataflow—and syntaxes map onto musical systems and structures
- The technical challenges of building an audio engine that supports arbitrary edits to its graph while supporting real-time, interruption-free playback
---

Corné Driesprong

I'm a polyglot (C/C++, Swift, JS, Rust) freelance software developer and musician with background in musicology and over a decade of experience across native, web and mobile application development. I'm currently particularly interested in (relatively) novel interfaces for musical expression, such as touch screens and live coding. When not programming, I can usually be found generating weird bleeps or playing drums in metal bands.

Keynote: Sonic Cartography - Navigating the Abstract Space-Time of Sound - Carla Scaletti - ADC 2024
---

From the chemotaxis of single-celled organisms to human exploration of the solar system, it seems that terrestrial brains are exquisitely tuned for navigating in 3-d space. There is evidence that we use our navigation brains, by way of conceptual metaphors, to reason about even the most abstract concepts. But what about when that space is infinite? How do we navigate within a virtual space that does not even exist until we generate it? This is the domain that audio developers inhabit and explore on a routine basis. And we’ve developed strategies that have analogs in biological evolution, anthropology, physics, computational equivalence, assembly theory and emergence. Audio developers are the under-appreciated protagonists of this story (but there is a happy ending).

Carla Scaletti

Co-founder of Symbolic Sound Corporation (https://kyma.symbolicsound.com/), Carla Scaletti is the creator of the Kyma language, a sound design environment used extensively in film, games, music, and scientific research.
In addition to her work as a software developer, Scaletti composes experimental electronic music for live performance, contemporary dance, and virtual reality. Since 1990, she has been one of the pioneers helping to establish the field of data sonification: using sound to explore, interpret, and communicate complex scientific data.
At the University of Illinois, she earned a doctorate in music composition with a minor in psychoacoustics, alongside a master's degree in computer science. Among her composition professors was Salvatore Martirano, creator of the hybrid digital-analog composing machine known as the Sal-Mar Construction (https://distributedmuseum.illinois.edu/exhibit/sal-mar_construction). Her computer science advisor, Ralph Johnson, was one of the ""Gang of Four"" who revolutionized software development with their book on design patterns for object-oriented programming (https://en.wikipedia.org/wiki/Design_Patterns).
During her time as a graduate student and post-doctoral researcher at the University of Illinois, Dr. Scaletti was a member of the CERL Sound Group, where she collaborated with a group of fellow students who would go on to notable careers in audio signal processing, among them:
• Kurt J. Hebel: Co-founder of Symbolic Sound and designer of Kyma's audio processing units.
• Lippold Haken: Founder of Haken Audio and inventor of the Continuum Fingerboard.
• Charlie Q. Robinson: Dolby researcher and winner of a 2024 technical Oscar for the Atmos audio format.
• Kelly Fitz: Principal DSP Algorithm Engineer at Eargo.com and developer of the Loris open source sound modeling & processing software
• Richard G. Baraniuk: Rice University Professor of Electrical & Computer Engineering and Founder of the open education initiative OpenStax

Perceptual Convolution - Fast and High-Fidelity Combined - Tobias Hienzsch - ADC 2024
---

Convolution plays a crucial role in modern music production, extending beyond classical reverberation to applications with neural networks and hardware emulation. The demand for efficient computation has long constrained real-time capabilities. Perceptual Convolution aims to address this challenge by computing only the segments of the impulse response (IR) that are perceptible to the human ear.

Identifying these acoustically important segments of the IR is the key challenge. In this presentation, we will explore the computational savings achieved, methods for analyzing existing IRs to enhance their efficiency, and the impact on performance and perceived audio quality. By focusing on perceptually relevant data, we can improve both the efficiency and the overall auditory experience.
