Modern Feedback Delay Networks for Realistic and Creative Reverberation - Gloria Dal Santo - ADC 2025
---

The Feedback Delay Network (FDN), originally proposed over 50 years ago, remains one of the most widely used structures for real-time artificial reverberation. An FDN consists of a set of delay lines combined with attenuation filters, interconnected through a feedback matrix. This topology simulates the recursive process of sound waves reflecting within an acoustic space. FDNs are computationally efficient, highly parametrizable, and provide a flexible framework for exploring a wide range of delay-based reverberation designs.

Recent research has focused on improving the efficiency and perceptual quality of FDNs to produce more realistic reverberation, particularly for spatial audio applications requiring multichannel systems. This talk will present an overview of the state of the art in FDN design, current research directions, and best practices for the challenging task of parameter design and tuning.

One of the most notable recent advancements includes the use of gradient descent optimization schemes to improve the smoothness and spectral coloration of FDNs, enabling a reduction in computational cost. Moreover, sparse filter-based feedback matrix design and grouped FDN topologies allow for modeling more complex acoustic scenes.

In addition to these technical developments, the talk will also explore how FDNs can be used for artistic applications, such as creating reverberation with intentionally unnatural characteristics, including time-varying behavior, shimmering effects, and reverb enhancement systems.

Optimizing UI Rendering Performance in Cubase and Nuendo - Erich Krey - ADC 2025
---

In this talk, I’d like to take you on a journey through how we significantly improved UI rendering performance in Cubase and Nuendo on macOS by integrating Apple’s Metal technology into our framework.
While I’ll provide some high-level insights into how UI rendering works in Cubase and Nuendo (Steinberg DAW), the main focus of my talk is the journey itself.
We’ll start at the point where we realized that our existing implementation no longer performed adequately on modern Macs, and follow the path through what we achieved, the key challenges we faced, and how we overcame them.
Hopefully, many of the concepts and solutions I present will be broadly applicable.
So—does all’s well that ends well?
Well, not quite. I’ll conclude by highlighting one key issue that still remains—an issue relevant to all of us developing DAWs or plug-ins.
---

Erich Krey

I’m an Application Performance Manager at Steinberg, where I’ve been working since 2013.

I’m passionate about all things related to performance. The first computer I ever used was a Macintosh Performa 630.

I work in a hybrid role—continuing to develop for Cubase and Nuendo while also collaborating with various teams at Steinberg and external partners. Together, we analyze performance issues, propose solutions, and plan the necessary fixes.

During my studies, I worked as a piano player in restaurants and produced an album with a friend. I still enjoy composing piano tracks to this day.

If you’re interested in chatting about performance, Cubase, Nuendo, or anything else, feel free to reach out!

Incline - Topographic Microsound Explorer - Cristián Vogel - ADCx Copenhagen 2026
---

In this talk from ADCx Copenhagen 2026, electronic musician, composer, and audio programmer Cristián Vogel introduces Incline, a native desktop instrument developed at his studio, Never Engine Labs. Moving beyond traditional time-ordered slicing and blind segmentation found in many granular synthesis tools, Incline treats the act of segmentation as the primary musical decision, putting compositional control back into the hands of the creator.

The core of Incline lies in its multi-dimensional analysis stage, where spectral data functions as the absolute source of truth. By processing fixed stereo files through a principal component analysis (PCA) algorithm, the software maps audio fragments onto a non-linear, navigable "topersonic" terrain based on spectral similarity rather than a chronological timeline. Vogel demonstrates how composers can perform these sounds by navigating the 2D surface manually, via MIDI, or through a built-in contour sequencer, offering three distinctive runtime behaviors—one-shot, one-loop, and multi-layer cloud modes—that allow similar spectral clusters to be recontextualized musically.

Vogel also shares the underlying development story, highlighting how modern frameworks like Rust, Fun DSP, Tauri, and the FluCoMa library from the University of Huddersfield made the software possible. Reflecting on the evolving landscape of software production, he explores the rising significance of AI-assisted development ("vibe coding"), which enables contemporary artist-engineers to bridge the gap between creative ambition and complex digital signal processing to bring entirely new instruments to life.

Building an Optimized DSP Framework in Modern C++ – Scott Carver – ADC 2025

Building an Optimized DSP Framework in Modern C++ - Scott Carver - ADC 2025
---

The introduction of C++23 and upcoming C++26 features have significantly expanded the potential for building expressive, manageable embedded domain-specific languages (EDSLs) that compile efficiently into optimized lower-level representations. Features like enhanced constexpr and consteval execution enable a single, descriptive and clear representation of audio DSP algorithms to generate multiple optimized versions tailored to specific execution contexts and runtime constraints.

Inspired by successful libraries such as Halide and Eigen, we will look at a prototype C++ library developed to explore clean separation between algorithm description, data structures, and execution strategies. It generalizes inner-loop optimizations vectorized across two dimensions, enabling consistent application of advanced optimization techniques across diverse DSP algorithms. The library provides us a collection of design patterns that we can use to formulate how a contemporary C++23/26 audio graph can be built.

This talk will explore practical techniques and simple examples for implementing these design patterns in modern C++, demonstrating how they collectively form a robust framework for defining and executing efficient DSP algorithms:

- Zero-cost Compile-time / Runtime Variant Values: Approaches to building scalar compile-time-constant and runtime-variant values, as well as more complex aggregate / property tree data structures, without incurring memory or performance penalties.
- Parametric Data Structures: Designing simple, readable data structures that can be optimized cache friendly access and vectorization.
- Expression Templates: Using C++'s template metaprogramming to defer computation, enabling optimized evaluation and graph transformations.
- Loop and Data Optimizations: Techniques for loop-invariant value hoisting, re-blocking, and linearization to improve memory and execution efficiency.
- Finite Difference Optimization: Automated optimizations for polynomials, trigonometric functions, and interpolation routines to minimize runtime computation.
- Unified Parallelism Models: Integrating voice-parallel and time-parallel computations within a single descriptive graph representation.
- Compile-time Graph Transformations: Leveraging constexpr to construct and optimize directed graphs representing DSP signal flows, including handling feedback loops and delays.
- Benchmarking Execution Strategies: Describing, benchmarking, and comparing graph execution strategies (time-parallel, voice-parallel, block-based), enabling parametric, empirical optimization decisions.
- Empirical Validation: Investigating whether and how these techniques improve DSP performance in realistic scenarios, with comparisons against established commercial and OS audio engines.

By applying these strategies, we demonstrate how a single algorithmic representation can flexibly handle multiple DSP use-cases—from polynomial interpolation and envelope generation to buffer read/write operations—significantly reducing redundant code and enabling focused optimization.

Furthermore, separating algorithm logic from execution strategies allows parameterizing benchmarks and optimizations based on CPU architecture and usage patterns, preserving algorithm clarity without embedding machine-specific details.

These strategies will be presented individually so they can be applied immediately in existing audio code-bases, and demonstrated within a unified framework context to highlight potential improvements in code clarity, performance, maintainability, testing, and benchmarking. Topics will be accessible for moderate-to-advanced C++ programmers, and anyone interested in exploring cutting-edge practices in modern audio DSP programming. Attendees will gain actionable insights, directly applicable techniques, and inspiration for advancing audio DSP code performance and clarity with modern C++.

How I Learned to Love the Docs - Documentation As Design Process for Music Tech Products - Astrid Bin - ADC 2025
---

Product documentation is often seen as a ""nice-to-have"" that comes at the end of the design and implementation process, and something that few small teams have time for. But for audio products - notoriously complex, serving a multitude of styles and purposes, usually with a conceptual model that isn't obvious to newcomers - communicating what a product does and how it works is crucial. So what do you do if there's no one to produce documentation?

I'm a music tech designer who has learned to love the docs. In this talk I'll share why I think documentation is so important (to you as well as your customers), how I learned to get good at writing it, and why I think it's a vital aspect of design. I'll explain how I think about docs (and some good examples), and through a case study of my first big user manual, I'll describe why I think documentation is secret the superpower design skill. In case you want to go straight home and write some documentation, I'll also prodvide suggestions of how to approach docs, when to start them, some tools I've found useful, and how to leverage the power of documentation to improve your products while they're still being developed.

Does it sound familiar to have the UI responsiveness drop as audio load increases, or have audio stuttering under intensive UI operations?
That an audio track sounds different every time it’s rendered?
And that you end up with a system that seems very hard to test without instabilities or generous timeouts and tolerance?

In this talk we’ll take a brief look at the technology, approaches and architecture you can employ to improve the lives of your own engineering department and build better software for your users!

We’ll identify common pitfalls like atomic variables (!), performance mitigation strategies that may end up hurting and why it could make sense to take a page from graphics architecture in terms of how you may want to structure your interprocess communication. A suggested approach will be evaluated for benefits and tradeoffs.

PolyBLEP & PolyBLAMP Demystified - Nis Wegmann - ADCx Copenhagen 2026
---

In this presentation from the Audio Developer Conference, Nis Wegmann demystifies the mathematical concepts behind PolyBLEP (polynomial band-limited step) and PolyBLAMP (polynomial band-limited ramp) techniques used to suppress aliasing in virtual analog oscillators. Geometric waveforms such as square, sawtooth, and triangle waves naturally produce harsh digital aliasing due to infinite harmonics folding back over the Nyquist frequency. Wegmann demonstrates the audible difference between naive signal generation and alias-free synthesis using these DSP correction methods.

Rather than relying on computationally heavy oversampling and filtering, the BLEP and BLAMP algorithms resolve aliasing by localizing corrections directly at the discontinuities of the waveform. Wegmann breaks down the relationship between these functions, tracing their roots back to the integration of a band-limited impulse. To transition these theoretical concepts into a highly efficient runtime implementation, the session explains how to approximate the infinite sinc function using cubic Catmull-Rom Hermite splines.

The talk concludes with a fully functional, self-contained C++ code walkthrough demonstrating a real-time anti-aliased oscillator. Wegmann outlines the step-by-step logic of tracking sub-sample discontinuities, shifting the correction polynomial, and applying it directly to a running sample buffer. This presentation provides audio developers and virtual analog designers with a clear, practical roadmap to deriving and programming efficient polynomial-based oscillators.
