Audio signal processing - A practical guide for coders (Level: Intermediate)
Limited Capacity filling up

This hands-on workshop will focus on building a deep, intuitive understanding of fundamental signal processing concepts with an emphasis on problems specific to audio. The session will be driven by coding examples of gradually increasing complexity rather than textbook definitions, axioms and theorems.

After finishing this workshop, participants will be able to build and analyse common audio signal processing systems and understand their key properties.

While maths cannot be fully avoided when discussing this topic, relying on mathematics will be kept to a minimum, and their usage will be demystified and explained in detail when necessary.

A C++/JUCE project with the coding examples, exercises and analysis tools used throughout the session will be shared with participants shortly before the workshop.

Build your first audio plug-in with JUCE (Level: Beginner)
Limited Capacity seats available

This workshop will guide you through the process of creating your first audio plug-in using the JUCE framework.
Writing an audio plug-in can be a daunting task: there are a multitude of plug-in formats and DAWs, working with live audio requires knowledge of real-time programming, and sharing data between the audio and GUI threads is full of subtleties. In this workshop you will learn from the experts the best practices in creating plug-ins using JUCE, with a focus on thread safety and DAW compatibility.

This workshop will cover
  • An introduction to JUCE
  • Configuring a plug-in project
  • Adding parameters to your plug-in and accessing them safely
  • Creating a basic GUI
  • Methods to simplify your plug-in’s code
  • Debugging and testing your plug-in

During the workshop attendees will create a simple audio plug-in under the guidance of the JUCE developers.

Turn a JUCE plugin into a hardware instrument with Elk Audio OS (All Levels)
Limited Capacity filling up

In this workshop we present strategies and tools, using which existing audio plug-ins can very efficiently be deployed on high-performance embedded Linux devices, using Elk Audio OS, which will be released as open-source shortly after the event.


  • Each participant will create a complete hardware instrument, on which one or more JUCE synthesizer and/or FX plug-ins are running natively.
  • It will be possible to alter a few central parameters using physical controls. The other parameters will be accessible from a laptop, phone or tablet.
  • Participants will have learned and practised the steps needed during the workshop.

Elk will provide all needed hardware: a Raspberry PI board, one of our custom audio shieds, and a board with the physical knob, button and LED controls. We will also provide all the necessary software – a package centred on the Elk Audio Operating System and a build server ready to build and deploy plugins on the boards.


Requirements for participants:
  • A laptop (macOS / Windows / Linux) with an SSH terminal.
  • A working installation of the latest JUCE and Projucer 5.4.5 to build the examples.
  • Basic Linux / BASH knowledge.
  • Optional, but a good plus: basic Python knowledge.
  • Headphones with 3.5mm jack connector.

Additional requirements for those that want to build their own plugins
:

Participants interested in setting up the toolchain before the workshop can get in touch with the organizers by writing to developers@elk.audio.

Build a synth with SOUL (Level: Beginner)
Limited Capacity filling up

The SOUL language and audio platform was announced last year at ADC2018 and has since been available for people to play with on our soul.dev website. In this workshop, its creators Julian Storer and Cesare Ferrari will introduce you to the syntax and structure of the language and help you to build a synthesiser from first principles. At the end, there will be some hardware devices available on which participants will be able to run their creations.
This workshop will cover:
  • How to use the soul.dev website or a local SOUL installation to write and test your code
  • The philosophy and principles behind the SOUL architecture and syntax
  • How to create the building blocks of a simple synth from scratch
Requirements:
  • A Mac or Windows laptop
  • Some basic familiarity with audio coding of some kind

Introduction to deep learning speech synthesis (Level: All)
Limited Capacity filling up

This workshop introduces the core concepts of modern deep learning based speech synthesis and allows users to learn-by-doing.
We will get hands-on experience with synthesising, training and analysing these research-derived models.
By the end, we will have a good understanding of how to make machines talk in a very human-like way.

  • 1st part: Introduction
  • 2nd part: Synthesise (Practical)
  • 3rd part: Understanding
  • 4th part:Training (Practical)
  • 5th part: Analysis/Evaluation (Practical)
  • 6th part: Where next? 
Session length: 1.5 hours

Writing applications with JUCE audio back-end and JavaScript front-end (React Native/Electron) (Level: Advanced)
Limited Capacity full

In this workshop we will focus on the integration of a React Native front-end (running natively on mobile and in Electron on desktop), a very popular choice amongst front-end developers not only for web applications but also for mobile and desktop platforms, with a JUCE based audio processing back-end. We will be writing code in C++, JavaScript (TypeScript), Objective-C and Java.
