Profiling Neural Audio Plugins - Dharanipathi Rathna Kumar - ADCx India 2025
---

Profiling is an indispensable tool in developing high-performance, real-time audio plugins. In this talk, we will delve into profiling, with a focus on neural audio plugins. We will explore key profiling techniques, including time profilers, system tracers, performance counters, and the distinctions between sampling and instrumentation. Using Xcode’s Instruments as our primary tool, we’ll walk through an example code to demonstrate how profiling can identify bottlenecks and guide optimization efforts. We’ll also briefly examine the performance of current neural network inference engines used in audio plugins.

Building Audio Applications using AI Models: Practical Lessons Learned - ChangHun Sung - ADC 2024
---

Supertone has been building and releasing a variety of AI audio applications since 2022. Ranging from a real-time noise reduction plug-in, a standalone voice changer application, to an impulse response generator that employs a transformer architecture (the kind used in LLMs), Supertone’s products were made by taking AI models from the lab and delivering them to the hands of users. In this talk, we will share with you some practical lessons we’ve learned from our experiences.

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

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

https://audio.dev/ -- @audiodevcon​

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 – ADCx India 2025

https://audio.dev/ -- @audiodevcon​

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.

Elliptic BLEP – High-Quality Zero-Latency Anti-Aliasing – Geraint Luff – ADC 2024

https://audio.dev/ -- @audiodevcon​

Elliptic BLEP - High-Quality Zero-Latency Anti-Aliasing - Geraint Luff - ADC 2024
---

BLIT/BLEP/BLAMPs are a useful tool to reduce aliasing in basic waveforms, nonlinearities, and hard-sync synthesis. There are many variations, but most of them require some lookahead and bookkeeping to work properly.

We start by looking at where aliasing comes from in these situations, how BLEP and friends can help, and the compromises of some common variations.

We'll then introduce a new IIR-based approach based on Holters-Parker resampling. This approach has a simple zero-latency implementation, and has extremely good aliasing-reduction based on elliptic filters.

An implementation will also be released as a zero-dependency open-source C++ library (single-file header). This can also be used as an arbitrary-rate resampler for modulated delay lines and sample playback.
