Motion and Music Modeling in Hindustani Classical Music - Tejaswinee Kelkar - ADCx India 2024
My talk will summarize of computational generative approaches in North Indian classical music (NICM). NICM presents a unique problem where non-quantization of notes, and the predominant characteristic use of pitch contours to express sonic differentiation means that quantized modeling of, for example, sheet based music goes only so far in being able to shape generative Hindustani music. I will present these approaches of notation based, and character based RNNs for generating Hindustani improvisation.
Generative musical AI in NICM is not really described as a task. However, pre-trained generative music models are modeled after common practise period based western music, and are definitely unsuitable to generate anything in this vocabulary. Sample based generative AI for NICM has, as of this abstract not been a field with separate exploration. Musical AI in NICM is mostly explored form the point of view of modeling raga and raga recognition tasks.
In my previous work, I have addressed how phrase generation models and contour models are perceptually important for tasks such as this. I will present an overview of the state of knowledge in the intersection of these fields and the SOTA of generative techniques in NICM.

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.

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.

Building a High Performance Audio Application With a Web GUI and C++ Audio Engine - Colin Sullivan & Kevin Dixon - ADC23
The era of using web UIs for audio applications is just beginning. How might we build a high performance audio application on the foundations of the JUCE web component ? How might we overcome some limitations of the JUCE web component, such as passing chunks of binary data to the GUI? How might we deal with the complexities of this dual-sided system written in two different languages? We have developed a solution for a high-performance application architecture including a C++ audio engine and a web GUI.
Both the C++ audio engine and web UI implement their own unidirectional data flow, and combine to form an application wide unidirectional data flow, allowing the GUI to send actions into the C++ application to initiate state changes. We will discuss tooling developed for sharing data types between the two languages without error-prone manual maintenance, as well as the communication protocol itself and how we overcame limitations by intercepting HTTP requests from the webview in the C++ application.
We will discuss the performance considerations of integrating the unidirectional data flow architecture with a real-time audio engine and the high-performance architecture of the Web GUI itself.

Kevin Dixon
I've been building consumer and professional music applications for both desktop and mobile platforms since 2008. Originally started work on a streaming video platform for public safety, I was immediately exposed to the issues of communicating between a high-performance C++ engine and with a garbage collected language (C#) for the GUI. After cutting my teeth on mobile development with the first Android G1 handset, I moved squarely into the audio industry. At Audyssey Labs, I was a founding member of their mobile team, and was responsible for integrating DSP technology into any OS or Firmware our client demanded, most notably the Android OS itself. I was a lead developer on a consumer hifi listening app for iOS and was awarded a patent (US9860641B2) for delivering audio output device specific audio processing from the cloud. From there, my mobile experience led me to Native Instruments, where I contributed heavily to both of Native Instruments mobile offerings, iMaschine and Traktor DJ, always with a focus on the audio engine and application architecture. Spending time in a product-focused environment taught me to be efficient with what makes it into the codebase, while still balancing overall quality (decisions in codebases always last longer than you think!). After brief, yet productive, stints with Fender and Dolby, I landed at Output and have been focusing on audio engine and application architecture for the past two years.

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.
