Squeeze C++ JUCE and Bottle It Into Linux Embedded Devices and More - Stefano Zambon - ADC 2024
---
Running JUCE applications on embedded Linux devices is not a new thing. The topic has been treated in previous ADCs and, most notably, at ADC 2016 Felipe Tonello introduced a repository for Yocto/OpenEmbedded to make the task easier.
However, several things have changed in the meantime both in JUCE and in the embedded Linux world. This talk will present a new integration between CMake-based JUCE projects and Yocto/Openembedded, targeting modern embedded Linux platforms using the Raspberry Pi as an example.
The focus will be on the entire embedded development workflow, showing how to build target filesystem that can be run on the devices, cross-compiling SDKs, and automated testing tools suitable for modern CI/CD integration.

Workshop: Klang - Live and Expressive C++ for Audio - Chris Nash - ADC 2024
---
A practical introduction to Klang, a C++ dialect (language extension) for audio, and rapIDE (rapid audio prototyping IDE), a complete C++ development environment in a DAW plugin, supporting live code editing, recompiling, and debugging. Developed to improve the liveness and usability of professional DSP practices, both tools facilitate the expressive design of new interfaces, sounds, and audio processes, while lowering the threshold to C++ for newcomers and learners, without compromising its expressive ceiling or performance.
ABOUT THE WORKSHOP
The workshop will feature discussions, live demonstrations, structured practical exercises, and assisted open exploration of the Klang language and rapIDE development platform, both available free for non-commercial use.
ABOUT THE TECHNOLOGIES
The Klang language (http://github.com/nashaudio/klang) is a single header include, compatible with any C++17 enabled platform, transforming C++ into an audio programming language with rich support for audio types, processes, and DSP primitives - notably also adding support for concise, explicit expressions of signal flow, allowing C++ code to more closely mirror block diagrams
The rapIDE IDE (aka Klang Studio; http://nash.audio/klang/studio) is a suite of cross-platform (Windows/Mac) audio plugins (in VST and AU format) that contain a complete integrated development environment (IDE) based on the LLVM/clang toolchain, supporting live, in-plugin coding, compiling, hot-swapping, analysis, graphing, and debugging without stopping the host (or even playback). Designed for rapid prototyping of C++ audio processes (e.g. synthesisers, effects), rapIDE is designed to integrate with existing workflows, such as desktop, embedded, and web audio development, but also provide a more immediate and immersive way to explore sound with C++.
FURTHER INFORMATION
Both technologies are pre-release and under active development, maintained by nash.audio, a non-profit organisation supporting projects in music and technology. Delegates require a Windows or Mac laptop, and are recommended to download and install rapIDE (aka Klang Studio) from nash.audio/klang in advance of the session.

Inheriting Mantis (Synth) from Chris Huggett - Ben Supper - ADC 2024
---
Chris Huggett founded the Oxford Synthesiser Company in the 1970s. He spent his career designing what became classic instruments: the EDP Wasp and OSCar synthesisers, most of Akai's samplers in the 1990s, and pretty much all of Novation's musical products.
In 2019, Chris took on a commission for a new company. Given creative free rein, he started developing a hybrid synth that revisited some of his earliest work, but improved it with modern features. Unfortunately, he was diagnosed with cancer at around the same time, and didn't survive the first lockdown.
Having worked with Chris for a while at Novation, and being a little involved with the same new company, I was standing in a footlight when the music stopped. With the permission of his estate, the contents of Chris's desk and hard drive allowed us to inherit a well-conceived, sometimes brilliant, but technically rough proof of concept. We were given permission to see what we might do with the hardware and software.
As a solo engineer, my job was to understand the context and intentions embodied in Chris's draft, to shape and polish it without losing his fingerprints, and to see it into production before the money ran out.
This talk will cover the technically interesting aspects of this project, following the evolution of Chris's demo into a manufacturable product and a codebase for the future, whilst working out which of his fingerprints he meant to polish out and which to leave.

How to Price an Audio Plugin - Factors to Consider When Deriving That One Elusive Value - James Russell - ADC 2024
---
A plugin's price can make or break its success in the market, so why is it often one of the last decisions made? And why do skilled DSP developers struggle to determine this one value? This talk will cover the relevant economics of pricing for digital products, and will lay out 12 factors that should influence the final decision, using real-world examples. Developers will gain insight into what questions to ask and what observations to make in pricing their next launch – whether it's an analogue-style EQ, a one-knob spectral compressor, or humanity's next legendary synth plugin.

Groove Transfer VST for Latin American Rhythms - Anmol Mishra & Satyajeet Prabhu - ADCx India 2025
---
Latin American music relies on groove---small variations in timing, dynamics, and other aspects---to create an expressive rhythmic feel in music performance. Electronic music production often attempts to replicate these qualities through algorithmic manipulations to achieve similar effects. In this work, we employ a transformer-based model to learn microtiming and dynamics from onset timing and strength annotations of Uruguayan Candombe drum performances. The model is then deployed as a VST allowing users to apply the learnt candombe micro rhythms to quantized midi drum performances. With this work, we aim to bridge the gap between algorithmic rhythm creation and the expressive qualities of live performance, striving to produce music with the authentic grooves of various Latin American genres.

Accelerated Audio Computing - Unlocking the Future of Real-Time Sound Processing - Alexander Talashov - ADC 2024
---
For the past 30 years, how we deal with sound has seen little change—from how we record music and edit sound to playback in various environments, including virtual spaces like games and VR, and real-world setups such as venues, cinemas, homes, and cars. The primary reason for this stagnation is the rarity of real-time audio processing on highly capable devices like GPUs and NPUs. Most consumer and professional systems still rely on outdated DSP chips that struggle to handle more than a few convolutions per channel, while CPUs are often tied up with non-audio tasks. At ADC, we reveal how we unlock the potential of GPUs by overcoming challenges related to latency, code parallelization, thread utilization, and others. Today, we’re excited to showcase how this technology can scale beyond DAW plugin use cases to professional music devices at our Workshop. We provided the power of Nvidia Jetson running Neural Amp Modeller (NAM) NNs natively as an example. We offered our Workshop participants access to our Platform tools and code that empower them to run the NAM project on the GPU and extend it further or innovate in ways others haven’t yet created. Join us at this keynote to explore our expansive vision for GPU-powered technology adoption and discover what’s possible for the future of audio beyond the plugins and digital guitar ampfliers.
