Spectral Audio Modeling: Why Did It Evolve and Do We Need It Now? - Julius Smith - ADC 2023

This talk summarizes historical developments in spectral audio synthesis and processing, touching on origins in evolution, musical practices, innovations at Bell Labs and CCRMA, and AI approaches today. Our ears continue to feed spectral decompositions to the brain, showing no signs of become vestigial in favor of purely neural processing in the brain. In machine learning, on the other hand, spectral representations are often being omitted in favor of time-domain waveform encodings. How do we reconcile this? Looking at continuing uses of spectral audio processing in AI, we find that AI and spectral processing remain partners and are likely to continue symbiotically for the foreseeable future.

A Comparison of Virtual Analog Modelling Techniques (Part 2) - Christopher Johann Clarke & Jatin Chowdhury - ADC23

This talk will explore the spectrum of virtual analog modelling techniques including traditional methods (modified nodal analysis, wave digital filters), single-architecture neural network models, and grey-box methods that incorporate both physical modelling and machine learning techniques. Several models of the gain stage from the Boss DS-1 guitar pedal will be provided as a motivating example. The talk will discuss how these methods can generalize over a wide range of circuits, as well as the specific problems that users of each modelling technique can expect to see for different types of circuits.

Deep Learning for DSP Engineers: Challenges & Tricks for Audio AI – Franco Caspe & Andrea Martelloni

https://audio.dev/ -- @audiodevcon​

Deep Learning for DSP Engineers: Challenges and Tricks for Audio AI - Franco Caspe & Andrea Martelloni - ADC23

This talk aims to tackle and demystify the process of the development of an AI-based musical instrument, audio tool or effect. We want to view this process not from the point of view of technical frameworks and technical challenges, but from that of the design process, the knowledge required and the learning curve needed to be productive with AI tools; particularly if one approaches AI from an audio DSP background, which was our situation when we started out.

We are going to quickly survey the current applications of AI for real-time music making, and reflect on the challenges that we found, especially with current learning resources. We will then walk through the process of developing a real-time audio model based on deep learning, from dataset to deployment, highlighting the relevant aspects for those with a DSP background. Finally, we will describe how we applied that process to our own PhD projects, the HITar and the Bessel’s Trick.

Exploration of Strongly-Typed Units: A Case-Study From Digital Audio - Roth Michaels - ADC 2023

API or math mistakes with units can cause problems ranging from a digital audio processing outputting silence to crashing your Mars rover—we’ll discuss real-life examples of both! The combination of user-defined types, conversion operators/constructors, and operator overloading in C++ give us the tools to use strong-types and avoid unit mistakes; std::chrono is a great example of this that everyone should be using. Unfortunately, when dealing with units beyond time many developers still use primitive types encoding units in variable names or comments because the standard does not offer any tools for user-defined units.

In this talk, we will look at the mp-units library which has been proposed for standardization in P1935 (A C++ Approach to Physical Units). We will look at the implementation of various units used in digital audio / DSP that go beyond “physical” units and what the experience is like to develop your own units with this library/proposal.
To close, we will look at things missing from P1935 that we as audio developers might need.

Implementation of an IIR Antiderivative Anti-Aliasing Wavetable Oscillator – Maxime Coutant – ADC23

https://audio.dev/ -- @audiodevcon​

Implementation of an IIR Antiderivative Anti-Aliasing Wavetable Oscillator - Maxime Coutant - ADC 2023

Anti-aliasing is a crucial consideration for digital audio synthesis. Usually, for an oscillator, techniques like band-limited signals or oversampling are employed to mitigate this problem, but I investigated a method a bit more recent : Antiderivative Anti-Aliasing (ADAA). My search for a practical ADAA application in wavetable synthesis first yielded limited results. However, a paper titled "Antiderivative Antialiasing for Arbitrary Waveform Generation," published in August 2022, caught my attention.

The presentation will focus on three aspects:

• An Introduction to ADAA and the algorithm itself
• Insights into practical implementation and results
• Reflections on engaging with Academic Research

By the end of the talk the listener will know about the pros and cons of this technique and how and when to employ it. Furthermore, we will have illustrated some challenges of working with academic material as a software developer.

Three RADical Concepts in the Art of C++ Coding – Chris Nash – ADC23

Three RADical Concepts in the Art of C++ Coding - Chris Nash - ADC 2023

What if MIDI was a programming language?
What if C++ had built-in audio semantics?
What if you could develop C++ plugins, live in the DAW?

This talk explores these ideas and the development of new technologies designed to blur the lines between music and code, for both artists and developers, and challenge traditional ways of thinking and working.

Drawing on concepts of flow, liveness, and rapid prototyping, the talk will present live demos, and discuss the development of:

Manhattan - a digital audio workstation and embeddable API built on a procedural music engine that integrates sequencing and programming. Used by artists, game composers, and in teaching computational thinking, example applications include crowd-driven music using machine vision, a Unity mini-game featuring a live (and somewhat mortal) orchestra, plus a growing library of famous works recomposed as code that shows the power of modelling music as both pattern and process.

Klang - an open C++ dialect (language extension) for audio, using modern language features (C++14/17) to extend the semantics of C++ to encapsulate audio, providing DSP primitives and types, and adapting the STL's concept of stream objects and operators to represent signals. Easier to read, more concise, and easily mapped to visual forms (block diagrams, Max), Klang feels like a new language (in the spirit of SOUL) but, as pure C++, retains the performance, portability, compatibility, and interoperability of the industry standard.

rapIDE - a C++ IDE inside a DAW plugin, designed for rapid audio prototyping and development of synthesisers and effects. Built on a full clang/LLVM-based toolchain, the plugin's source code can be live edited, rebuilt, reloaded and auditioned without restarting the DAW (or stopping playback). Compatible with C++ and Klang, rapIDE is designed to improve the accessibility, liveness, and immersion of audio programming, for applications in rapid prototyping and teaching, featuring realtime debugging, auto-complete, code sandboxing, and built-in audio analysis.

These technologies will support the new Music Systems Engineering (MuSE) degree programme, in development by Point Blank Music School in collaboration with industry, for launch in 2024.
