Vars, Values and ValueTrees: State Management in JUCE - Jelle Bakker - ADC 2023

Managing various types of state, including global settings, presets, UI state, and application state, is crucial for building robust software. But, it comes with a challenge. State must be synchronized throughout the app. State must be stored and restored. And state is everywhere. There seems to be a lot of debate about what the best way is to solve these problems. The concept of centering your app around a model, a single point of truth, has long been recognized as a powerful pattern, often referred to in the context of MVC (Model-View-Controller). Adopting this approach will make extending and maintaining your software simpler. In JUCE you will find many classes designed for dealing with state, such as the AudioProcessorValueTreeState, ApplicationProperties, Value and Vars. This talk will serve as a guide and overview for how to manage data in JUCE applications.

Using Convolution for Archeo-Acoustic Conservation - Akash Sharma - ADCx India 2024

Every space has its unique acoustic properties because of the combination of its dimensions, architectural design and use of construction materials. Time over centuries has enriched and created an invigorating experience of space which now is part of our heritage; all our sensory realms have fused into this memorable image of space. We can use computation to determine this unique acoustic property.

How to Write Bug-Free, Real-Time Audio C++ Code? - Jan Wilczek - ADC 2023

How many times have we compiled our audio plugin or app and launched it only to find out that "something is glitching"?

How can we be sure that we submit a correctly implemented audio feature in a pull request?

And how can we detect existing problems and precisely locate them in our codebase?

I've been pursuing the answers to these questions from my day 1 in the audio industry and in this talk I am going to share with you my personal favorites. This is not just from my experience; I've actively asked community members for their strategies at every opportunity I got. This is a collected wisdom of more than just a single developer.

In the talk, I will:
1. Outline why shipping bug-free code is vital for your business and your own sanity
2. show you simple yet profound strategies for ensuring software correctness based on digital signal processing (DSP), including:
1. taking advantage of phase cancellation properties
2. leveraging the power of the FFT for frequency-manipulation algorithms,
3. underused DSP tools like total harmonic distortion (THD), Farina sweep, and pole-zero plot,
4. discovering the power of reference audio renders.
3. explain how to safely reuse stable and tested DSP code of other developers,
4. interoperate C++ and Python for accessing powerful numerical libraries and testing complicated scenarios
5. correctly implement even the most advanced DSP algorithms and optimizations,
6. show real-world examples where these principles helped solve hidden audio bugs, including
1. pitch tracking,
2. pitch shifting, and
3. the flanger effect.
With this knowledge you'll be able to:
1. approach developing new features with greater confidence,
2. enjoy more inner peace during development, review, and deployment,
3.write correct audio code every time!

Virtual Acoustics: Recreating Natural Phenomena in the Digital Domain - Aidan Baker - ADC 2023

Audio in the VR / AR domain may become a dominant section of this industry in the coming years. While methods for processing spatial audio already exist (and formal standards have been created and utilized) another factor of immersive audio remains (mostly) untouched: Virtual acoustic systems that mimic the virtual spaces.

This talk will go over various techniques for handling room acoustics in both real-time and offline settings, and going over both their benefits, as well as their drawbacks. Additionally, we will look over how to go about approximating room acoustics without breaking the proverbial (cpu) bank.

Motion and Music Modeling in Hindustani Classical Music – Tejaswinee Kelkar – ADCx India 2024

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.

https://audio.dev/ -- @audiodevcon​

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.
