How to Price an Audio Plugin - Factors to Consider When Deriving That One Elusive Value - James Russell - ADC 2024
---

A plugin's price can make or break its success in the market, so why is it often one of the last decisions made? And why do skilled DSP developers struggle to determine this one value? This talk will cover the relevant economics of pricing for digital products, and will lay out 12 factors that should influence the final decision, using real-world examples. Developers will gain insight into what questions to ask and what observations to make in pricing their next launch – whether it's an analogue-style EQ, a one-knob spectral compressor, or humanity's next legendary synth plugin.

Groove Transfer VST for Latin American Rhythms - Anmol Mishra & Satyajeet Prabhu - ADCx India 2025
---

Latin American music relies on groove---small variations in timing, dynamics, and other aspects---to create an expressive rhythmic feel in music performance. Electronic music production often attempts to replicate these qualities through algorithmic manipulations to achieve similar effects. In this work, we employ a transformer-based model to learn microtiming and dynamics from onset timing and strength annotations of Uruguayan Candombe drum performances. The model is then deployed as a VST allowing users to apply the learnt candombe micro rhythms to quantized midi drum performances. With this work, we aim to bridge the gap between algorithmic rhythm creation and the expressive qualities of live performance, striving to produce music with the authentic grooves of various Latin American genres.

Accelerated Audio Computing - Unlocking the Future of Real-Time Sound Processing - Alexander Talashov - ADC 2024
---

For the past 30 years, how we deal with sound has seen little change—from how we record music and edit sound to playback in various environments, including virtual spaces like games and VR, and real-world setups such as venues, cinemas, homes, and cars. The primary reason for this stagnation is the rarity of real-time audio processing on highly capable devices like GPUs and NPUs. Most consumer and professional systems still rely on outdated DSP chips that struggle to handle more than a few convolutions per channel, while CPUs are often tied up with non-audio tasks. At ADC, we reveal how we unlock the potential of GPUs by overcoming challenges related to latency, code parallelization, thread utilization, and others. Today, we’re excited to showcase how this technology can scale beyond DAW plugin use cases to professional music devices at our Workshop. We provided the power of Nvidia Jetson running Neural Amp Modeller (NAM) NNs natively as an example. We offered our Workshop participants access to our Platform tools and code that empower them to run the NAM project on the GPU and extend it further or innovate in ways others haven’t yet created. Join us at this keynote to explore our expansive vision for GPU-powered technology adoption and discover what’s possible for the future of audio beyond the plugins and digital guitar ampfliers.

MIDI FX - Node based MIDI Effects Processor - Daniel Fernandes - ADCx India 2025
---

MIDI FX is a free and open-source MIDI effects processor which lets users build their own effects by freely connecting effect nodes together. It includes simple nodes for changing properties of a MIDI message, such as the note number or velocity; and also more interesting features like viewing the name of the chord you're playing, visualizing Continuous Controller values as they change, and practice playing randomized chords.

Since MIDI FX runs in the browser, it can use browser APIs to, for example, allow wireless MIDI communication between devices via WebRTC or convert an Arduino’s serial output into MIDI messages, which is very handy for DIY MIDI instruments. This, paired with its flexible design, allows users to create custom MIDI setups that are tailored to meet their needs.

The Curious Case of Subnormals in Audio Code - Attila Haraszti - ADC 2024
---

Floating-point subnormals have long presented an interesting edge case in digital signal processing that can cause severe performance hits, particularly when dealing with decaying infinite impulse response (IIR) filters. Most audio applications therefore opt to set flush-to-zero (FTZ) and denormals-are-zero (DAZ) CPU control register flags in their workflows.

The talk will chart an exploratory journey prompted by failing platform tests for web audio and an ancient ECMAScript forum thread, leading the author to investigate the current situation and impact on common devices.

Are subnormals still a problem for floating-point arithmetic in 2024? Is there a difference between native and web targets? What does the future hold for fast math and cross-platform audio code?

Quality Audio for Low Cost Embedded Products - An Exploration Using Audio Codec ICs - Shree Kumar, Atharva Upadhye - ADCx India 2025
---

Designing a decent quality audio solution at a low cost is an important challenge in embedded systems. This is made tricky as the bar for audio quality is set pretty high by everyday consumer products, which rely on highly integrated solutions. Consumer solutions achieve low cost, but that comes with the requirement of high volumes production. Embedded products typically do not scale to such volumes, which is what makes this a challenge.

With microcontroller based solutions, narrowing down the proper choice of components is an iterative process, especially for teams that have not dealt with audio at the lowest levels. The last mile cost optimization can be non-obvious, needing to push things down to clocking architecture.

In this talk, we will walk through a few audio solutions we investigated using audio codec ICs, with various cost/quality tradeoffs: Cirrus Logic WM8758, Princeton Tech PT8211, finally settling on Everest Semiconductor ES8388. The base hardware board is based on the Raspberry Pi RP2040 microcontroller, making good use of the PIO peripheral. We will cover essentials such as the I2S interface (master/slave), and codec configuration. We will also explain the clocking architecture (and software implementation) that eliminates the discrete crystal sometimes required for the codec, achieving the lowest cost per board.

Workshop: Inclusive Design within Audio Products - What, Why, How? - Accessibility Panel: Jay Pocknell, Tim Yates, Elizabeth J Birch, Andre Louis, Adi Dickens, Haim Kairy & Tim Burgess - ADC 2024
---

Following the success of last year’s ‘An Introduction to Inclusive Design of Audio Products’ https://youtu.be/-iVDiV1Iwio we are delighted to be presenting a follow up this year. The session will promote the work happening across the audio industry to support accessibility and inclusive design. We will focus on providing practical design principles for attendees to take away, backed up by engaging lived experience insights and demonstrations.

In particular, we will showcase the practices of two companies who have been making big waves within accessible music in the last year: Ableton and Arcana Instruments. Jay Pocknell and Tim Yates will be exploring how these companies involved the disabled musician community throughout the design of their products, as well as sharing accessibility top tips for attendees to take away, along with insights from musicians Elizabeth J. Birch, Andre Louis, and Tim Burgess.

Why is this important?

As the audio industry seeks to improve diversity within its workforce, and the music industry seeks to widen the diversity of artists creating music, it is essential that inclusion becomes woven into the design of the tools available.

But what do terms such as accessibility and inclusive design actually mean? How might developers begin to adopt inclusive design practices so that their software becomes accessible to a wider audience? What are some of the big-name audio companies doing to support accessibility and how can you learn from their experience?

These are the kind of questions that this workshop seeks to answer.

Panellists

• Chair - Jay Pocknell (RNIB / Sound Without Sight)
• Tim Yates (Drake Music)
• Elizabeth J. Birch (Musician / Accessibility Consultant)
• Andre Louis (Musician / Accessibility Consultant)
• Tim Burgess (Musician / Accessibility Consultant)
• Adi Dickens (Accessibility Specialist, Ableton)
• Haim Kairy (CEO, Arcana)

Outline

1. Introductions from all panellists.
2. Overview of the social model of disability.
3. Why design inclusively? The importance of accessibility in mainstream audio technology.
4. Inclusive design principles and best practice guidelines for music-making and audio products, including examples from products already on the market.
5. Case study – Developing with the community: what Ableton have learnt since investing in accessibility and connecting with their user community during the development of Live 12, Note, and Move. Andre Louis will also demonstrate the accessibility features of Ableton Move.
6. Case study – From the ground up: how Arcana built a company around inclusive design and developed their first instrument, the Arcana Strum, for all.
7. Panel Q&A. All panellists.
8. Call to action. How to learn more, further resources to explore.

Crunching the Same Numbers on Different Architectures - Analysis of the Different Architectures Used in Embedded Audio Signal Processing - Marco Del Fiasco - ADC 2024
---

DSP, microcontroller or a general purpose CPU? What are the major factors affecting design choices in embedded systems today, and how do they compare in terms of computational speed?

Since 1978 DSP chips were invented to cope with some limitations of existing CPUs. Audio processing has always been challenging because of inherently high demand for both throughput and low latency processing features. This led the chip manufacturers to develop specific architectures for such challenging tasks.

During the years the increasing demand of computation led also to develop on-chip hardware accelerators for specific tasks like FIR, IIR and DMA, making the machines more and more performant generation after generation. Hardware acceleration is great, but has a drawback: the design then becomes more and more architecture-locked, preventing a faster renewal of the OEM platforms and the embracement of new emerging technologies.

While the DSP world was evolving, also the general purpose CPUs made very big steps forward in terms of computational speed. They typically run with some high end operating systems like Linux that offer a wide set of ready to use features such as networking, USB, BT… and a huge number of available libraries you can use to fasten the audio application development cycle. This makes them very attractive in terms of flexibility.

In the middle, between specialised DSPs and general purpose CPUs there are microcontrollers. They integrate some other hardware that a product usually requires and provide low power operation. We will explore why they are one of the choices available and how they position in terms of computational performance.

The aim of this talk is to give an overview of the different architectures used in embedded audio signal processing, their advantages and disadvantages, and try to compare them with a holistic view. This will take into account computation power, ease of use, BOM cost, power requirements, expandability and give an overview of why all the architectures are still there in 2024 competing after so many years.

We will make use of real code for the comparison that will also highlight how the different chip architectures have an impact on code design.

Will there be any winner?
