What Is the Future of Immersive Music? - Ruth Farrar, Andrew Scheps, Hans-Martin Buff, Adrian Utley and Theo Kozlowski - ADC 2024
---

There is a dramatically increasing demand for artists and audio professionals to create content specifically for 3D-immersive listening on headphones and at home plus new audio experiences as demonstrated by venues such as Lightroom (London), Dareshack (Bristol) and Sphere (Las Vegas).

Most immersive music content, however, is re-purposed stereo productions never intended to be heard outside the two-speaker stereo environment with resulting output feeling disconnected and unfulfilling.

Record companies and artists want to avoid paying for post-production immersive audio mixes of original stereo recordings. They are increasingly requesting music studios deliver cost-effective ways for recording music from the outset in both stereo and immersive formats.

In this panel talk, the makers of 'Flow', Real World Studios, Dr Ruth Farrar from Bath Spa University and Adrian Utley from the band Portishead will share knowledge gained during this immersive music project. They will share insights from their trial to develop new immersive audio processing workflows to overcome current challenges of moving between stereo and immersive formats. They will also discuss their process for developing equipment set-up and sound capture approaches to create novel immersive audio compositions, elevating production processes from traditional stereo to being truly immersive.

Panel members include Hans Martin-Buff, Andrew Scheps, Adrian Utley, Theo Kozlowski and Ruth Farrar.

How Long Will It Take? Using the Cynefin Model and Probabilistic Forecasting in Software Projects – Simon Holt & Ross Chisholm – ADC 2024

https://audio.dev/ -- @audiodevcon​
---

How Long Will It Take? Using the Cynefin Model and Probabilistic Forecasting in Software Projects - Simon Holt & Ross Chisholm - ADC 2024
---

In this talk we explore forecasting for software projects, particularly at longer range when scope and specifications may not yet be fully known.

We look at the Cynefin model, to help assess whether a project or piece of work is Complex or Complicated, and why it matters.

From that assessment we look at which of the many Agile framework methodologies and tools are right for the job at hand.

- How do Business, Operations, Hardware and Software efforts interact, and how do our burn up/down charts work together with Waterfall planning?
- How to estimate backlogs (Scrum or Kanban), especially early in the project?
- What are the other factors in our delivery strategy to consider?

Key takeaway:- We look at probabilistic forecasting, as part of Actionable Agile, and how important this has become at Focusrite for helping us forecast “How long will it take?”

Background

Whatever the size and nature of your company or day to day work, if you have customers and perhaps also competitors, you will probably have encountered a situation where someone depended on something you were doing.

In a larger company, perhaps with investors, a competitive market, sales channels and a customer base, the level of confidence you have in your development approach becomes quite important. In a smaller company or start up, you still have to eat and pay rent, there is effort and cost for marketing and product launches, with holiday season(s) and trade shows to hit. If you’re also making hardware things of any kind, you have to physically build them (lots) and get them to people (all over the place). The importance of quality, reputation and brand may vary a bit, but beyond the early adoption phase of a product, customer trust is important, and we can’t compromise there too much for too long.

Devices and workflows are increasingly inter-connected, with more features and functionality meaning that products and technologies are increasingly more complicated. To keep the workflow and UI simple, it usually belies the amount of technology and complexity under the hood and at work in the background.

So in a world where market competition is often increasing, customers increasingly expect more, and any changes to a plan you had will create extra effort and knock on impact … How can we increase our confidence when answering the question “How long will it take?”

The Intersection of Analog and Digital Audio Processing - An Introductory Guide to Virtual Analog Modelling - Sohyun Im - ADC 2024
---

Audio circuits, such as guitar pedals and amplifiers, process input signals to output signals with specific audio effects. The process of replicating the electrical behaviour of these circuits in a digital environment is known as Virtual Analog (VA) modelling. This session aims to provide a basic understanding of VA modelling and explore various methods to achieve it. Finally, using these methods as a foundation, we will look at modelling the circuit of the MXR Distortion+ guitar pedal and examine the process of creating a real-time safe audio plugin that emulates the reference circuit’s behaviour.

Perceptual Convolution - Fast and High-Fidelity Combined - Tobias Hienzsch - ADC 2024
---

Convolution plays a crucial role in modern music production, extending beyond classical reverberation to applications with neural networks and hardware emulation. The demand for efficient computation has long constrained real-time capabilities. Perceptual Convolution aims to address this challenge by computing only the segments of the impulse response (IR) that are perceptible to the human ear.

Identifying these acoustically important segments of the IR is the key challenge. In this presentation, we will explore the computational savings achieved, methods for analyzing existing IRs to enhance their efficiency, and the impact on performance and perceived audio quality. By focusing on perceptually relevant data, we can improve both the efficiency and the overall auditory experience.

Pipewire: The How, What and Why of Audio on (Embedded) Linux - Daniel Strübig - ADC 2024
---

Understanding the audio ecosystem on Linux is not straight-forward.

Alsa, who? Pulse-audio, what? And what is this Pipewire everyone keeps talking about?

In this presentation, we want to provide a brief overview of the audio subsystem on Linux, looking at libraries provided by the kernel and how to work with it when writing user-space applications. Our goal is to clarify some of the confusion around the different libraries and tools and empower people to embrace the ecosystem instead of being intimidated by it.

Lastly, we would like to give a hands-on introduction to Pipewire, a new audio server shipped in many Linux distributions. We will cover how Pipewire works and how we use it professionally on our embedded linux platform. We will also show how to configure, introspect and debug the pipewire daemon, all the way to creating DSP chains by simply writing a small config file.

“Engine-Swap” on Two Spatial Audio Plugins Will Be Easy, Right? – Lessons Learned – Domenico Stefani

https://audio.dev/ -- @audiodevcon​

“Engine-Swap” on Two Spatial Audio Plugins Will Be Easy, Right? - Lessons Learned - Domenico Stefani - ADC 2024
---

Tackling a project that involves swapping the cores of two audio plugins seemed straightforward at first:
Yes, spatial audio is complex, but these are two similar JUCE plugins and I can just swap the core code components, it will be easy, right?
It wasn't, and it uncovered many unexpected challenges and learning opportunities.

In this talk, I will share my experience of improving an existing spatial audio plugin (SPARTA 6DoFConv) by replacing its convolution engine with a more efficient alternative. This process required deep dives into complex and sparsely commented audio DSP code and problem-solving.

The core of this presentation will focus on the general learning points from this endeavor. I will discuss some of the strategies I employed to understand and navigate complex codebases and the practical steps taken to embed a new convolution engine in an audio plugin. Additionally, I will explore the unforeseen issues that arose, such as dealing with the drawbacks of highly optimized algorithms and integrating a crossfade system, compromising between efficiency and level of integration.

This talk aims to provide valuable insights for developers, especially those who are starting out and want to start understanding and customizing other people's code. Join me in exploring the lessons learned, strategies employed, and trade-offs considered in creating a more efficient six-degrees-of-freedom spatial audio plugin.

Key Points:

Addressing challenges with optimized algorithms and accepting tradeoffs;
General lessons learned and best practices when working with other people's plugin code;
Practical knowledge of different multichannel convolution engines for Ambisonics reverberation and 6 degrees-of-freedom navigation for extended reality applications.
