Aliasing and Oversampling for DSP Engineers - Sam Fischmann - ADC 2023

Aliasing distortion and oversampling have become especially popular discussion topics in the wake of widely-available consumer analysis tools such as Plugin Doctor. In response, audio software users have been more vocal about aliasing, in many cases asking audio developers to provide oversampling.

As it turns out, not all oversampling is the same, we face several trade-offs when implementing it, and we don’t always need it. This talk aims to help you understand aliasing distortion, how oversampling addresses it, and some potential downsides of overuse. It also provides guidelines to help you decide when oversampling is necessary, what kind of oversampling to use, and mentions some open-source libraries that give you flexibility to make the right decision for your software.

NO MORE CODE: Introducing a New Graphical Programming Language for Audio Research and Developers - ChangHun Sung - ADC 2023

Audio software development is rapidly moving towards incorporating machine learning-based processing. While research scientists are continuously presenting us with inventive results in the field of AI, there is a lack of software engineering tools to utilize these results.

We are introducing a new development framework to bridge the gap between AI researchers and software engineers, allowing both fields to work together seamlessly.

By borrowing some concepts from functional programming languages, we designed a new node-based graphical programming language for audio software development, which is capable of handling a variety of data types including audio, multi-dimensional tensors and MIDI. Furthermore, the system is designed to support looping and branching logic using only nodes and node connections. This allows the implementation of highly flexible data processing algorithms.

Finally, as an AI voice technology company, we will present a demonstration of the plug-ins developed using our new programming language, showcasing its adaptability and advanced capabilities.

Developing an AI-Powered Karaoke Experience - Thomas Hézard & Clément Tabary - ADC23

Karaoke has been of popular interest for many years, from the first karaoke bars in the 1970s to the karaoke video games of today, and the recent progress in deep learning technologies has opened up new horizons. Audio source separation and voice transcription algorithms now give the opportunity to create a complete karaoke song, with instrumental track and synchronised lyrics, from any mixed music track. Real-time stems remixing, pitch and tempo control, and singing quality assessment are other useful audio features to go beyond the traditional karaoke experience. In this talk we will discuss the challenges we had to tackle to provide our users with a fully automatic and integrated karaoke system adapted for both mobile and web platforms.

Writing Elegant DSP Code in Rust - Chase Kanipe - ADC 2023

Rust has become an exciting alternative to C++ for audio programming. This talk will explain how Rust's unique type system can be leveraged to create elegant DSP code, with an emphasis on conciseness, clarity, and safety.

The talk will show that many features of audio programming DSLs can be achieved using advanced features of the Rust type system, and how Rust's zero-cost abstractions can be used to create DSP elements that are flexible, composable, and don't compromise performance. It will also show how to instantiate and implement audio processing graphs in imperative, functional, and declarative styles.

Confluence of Code and Classical Music: Ragas, Bach & Sonic Pi - Nanditi Khilnani - ADCx India 2024

In this talk, we delve into the surprising parallels between the worlds of code and classical music, uncovering the shared attributes that connect these seemingly disparate domains. Both code and classical music are driven by structure, precision, and creativity, demanding a similar mental landscape and cognitive approach.

Drawing inspiration from both Western and Indian classical music traditions, we discover the invaluable compositional methodologies and rules hidden within these musical forms. We will explore how these time-tested principles can seamlessly translate into algorithms that could be innovative co-composers in the process of music creation.

Using Sonic Pi, we’ll demo some Baroque compositional methodologies like Canons, Retrograde Inversions & Fugues as well as algorithmic Raga-based improvisations to realise how code inherently lends itself as a fitting medium for classical compositions and how this combination births some effective melody-making processes.

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.

https://audio.dev/ -- @audiodevcon​

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.

Democratization of Audio Dev: How it Started, Where it's Going - Aurelius Prochazka

In 2018, I gave a keynote at the ADC Conference in London. In that keynote, I discussed how audio developers can benefit from opening development to all, and how to escape the errors of past and design for the future. What did I get wrong? Did I get anything right? In this talk I'll give an overview of where we are now and update where things might be going.
