Keynote: Music Informatics for Musics of India - Topics, Tools and Trends - Ajay Srinivasamurthy - ADCx India 2025
---
The art of music has been practised for centuries in India. In the last century, the science of music developed, with musicologists studying music systematically using a scientific approach. Engineering of music is now emerging - music Informatics is a multidisciplinary field that draws from several fields such as acoustics, psychoacoustics, signal processing, machine learning, computer science, psychology and musicology to build tools and techniques for performance, production, analysis, understanding and synthesis of music. The tools aim to create a novel experience with music for both musicians and the audience, enhancing our collective experience with music. This talk is aimed to be an introductory overview of music informatics as it is applied to the diverse musics of India discussing the opportunities, challenges and application trends in the field. The talk discusses the current state of the art, relevant problems and resources available to start working on music informatics problems in the Indian socio-cultural context.

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 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.

I've been part of 'the plugin industry' since 2012, first at Computer Music and FutureMusic magazines, then as part of my own company, Egg Audio, which is a marketing agency and consultancy working only with plugin developers. I specialize in an industry rather than a type of service, so I and my freelancers provide everything from blog and video content to influencer marketing – all to music software companies including Sonible, Plugin Boutique, Waves and Rhodes.

Intro to Software Development of Audio Devices - From Plugins to Hardware - Wojtek Jakobczyk - ADC 2024
---
Many audio software developers are working on PC or Mobile only, building plugins, DAWs, various applications. There is the whole world of developing physical audio products - synthesizers, grooveboxes, effect pedals or eurorack modules, that is unknown to them. Working with these may seem very different, strange and scary. The notion of "embedded software" may have bad reputation. Nowadays, the truth about developing on hardware is far more nuanced, if not very different.
The purpose of the talk is to show why developing software for hardware can be fun and satisfying and that it's not that much different to working on a PC or mobile.
A review of typical architectures of such products will be presented - starting from hardware itself, but focusing on software aspects - operating systems, programming languages in use and aspects that may be different to PC architecture - such as differences in (or lack of) threading or handling of interrupts.
Last but not least - some tips on how to get started in the field - review of recommend prototyping hardware platforms, interesting software platforms and open source projects.

I'm passionate about making electronic music instruments that have physicality and give a feeling of something real and alive.
In the same time, I've been interested in making software since forever :).
Luckily, I can join the two passions working at Polyend, where we make synthesizers and grooveboxes.

Scalable, Efficient Processing and Analysis of Large Audio Datasets - Pawel Cyrta - ADC 2024
---
The exponential growth of audio data necessitates robust and scalable solutions for processing and analysis. This presentation introduces a novel approach to handle a colossal audio dataset (e.g 40 or more TB) using various methods and Ray framework for distributed computing.
When you have terabytes or petabytes of data, it is difficult to use python to process it and finish it before the asterisk. Distributed computations are now easy to perform thanks to the ray.io framework. I will show you how to use distributed methods in practice based on my experience in analyzing and training ML audio, speech and language models. With a wide range of applications, we always face the elementary problem of data preparation, and the dynamically created Ray cluster with calculation and optimization pipelines speeds them up many times. It will show you the basics of the environment, how to navigate and prepare production-ready applications. In this talk, we provide practical tips on how to manage data to build a scalable/robust/reliable software system.We will delve into specific use cases, including the feature extraction like Mel-frequency cepstral coefficients (MFCCs) and spectrogram analysis, showcasing how Ray’s flexibility and scalability can transform conventional audio processing workflows.
The presentation will conclude with a discussion on aggregating results and deriving meaningful insights from large-scale audio data, providing attendees with actionable strategies to manage and analyze vast audio datasets effectively.
Join Paweł as he shares invaluable insights and practical tips to master massive audio data distributed parallel processing.
