Auralization and Active Sound Design with Spatial Audio on a Vehicle Simulator - Joshua Chaiphas - ADCx India 2025
---

With the rise of electric vehicles, autonomous driving, and smart mobility, the contributors to a vehicle's sound are no longer limited to engine and powertrain noise but include synthesized and curated sounds known as Active Sound Design. Modern vehicles act as immersive experiential spaces, where infotainment systems play a key role in shaping driver/passenger experiences. As manufacturers implement advanced spatial audio technologies such as Dolby Atmos and MPEG-H, the in-car audio demands innovative approaches in spatial audio rendering, signal processing, and simulation tools. This talk will explore these challenges and present a design of a spatial audio auralization tool to test immersive audio content, offering applications for engineers, researchers and musicians, bridging the gap between creative and technical development.

Debugging Audio Content With Visuals - A Debugger Extension and Some Other Helpful Tools - Maxime Coutant - ADC 2024
---

A debugger is a crucial tool to any developer. But how much time did you spend on a breakpoint, sitting in front of a hundred of audio samples, with no idea on how to interpret them?

A good way to get information from these samples is to plot a graphical representation : waveforms, spectrograms... but it's not always straightforward to create such visualizations, especially when working with compiled languages like C/C++

In this talk, I would like to first review all the tools I discovered and tried these past years, with the goal of making my life easier when debugging audio.

Then, most importantly, I will present a tool I have started developing myself these last months with the objective to solve this issue. A debugger extension which adds new commands, to display the audio content directly from one's buffer classes. No need to recompile your code, nor to instrument it with macros or custom libraries.

Inheriting Mantis (Synth) from Chris Huggett – Ben Supper – ADC 2024

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.

Ben Supper

Ben engineers synthesisers, loudspeakers, MIDI controllers, and other products for various companies, and sells spatial audio hardware via his own company, Supperware.

He likes solving problems that combine elements of acoustic design, hardware, firmware, DSP, and application development. The first half of his career was spent mostly at Focusrite and ROLI, running the latter's R&D team and realising that he prefers the lab to the boardroom, but doesn't get to choose.

Ben's been involved with ADC since it started in 2015. He's spoken about MIDI, spatial audio, the craft of making hardware, and on weathering a demanding and satisfying trade, the practitioners of which are often invisible.

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.
