Overview

This repository is a collection of real-time audio effect algorithms implemented in C++. Each effect class is also demonstrated as an audio plug-in (Built using the JUCE Framework).

Effects Implemented

The effects implemented are the following:

• Time-Based:
  • Digital Delay
  • Reverb
• Modulation Effects:
  • Flanger
  • Chorus
  • Vibrado
• Distortion:
  • Vaccum Tube
  • Diode
  • Soft Clipper
  • Hard Clipper
  • Asymmetrical Clipping Distortion
• IIR Filters
  • 2nd Order Butterworth Low-Pass Filter
  • 2nd Order Butterworth High-Pass Filter
  • Peaking Filter
• Dynamic Effects:
  • Compressor
  • Limiter
• Utility Classes:
  • Comb Filter
  • Comb Filter (w/ Linear Interpolation)
  • Modulated Comb Filter
  • All-Pass Filter
  • All-Pass Filter (w/ Linear Interpolation)
  • Modulated All-Pass Filter
  • LFO (Low Frequency Oscillator)
  • Envelope Detector

Building

Prerequisites

Clone the repo and initialize the submodules by running:

git clone https://github.com/tr3m/digital-audio-effects
cd digital-audio-effects
git submodule update --init --recursive

Building the Plug-ins

The source code and CMakeLists.txt files for building each plugin can be found in the plugins directory.

Building on Windows

cd plugins/<plugin-to-build>
cmake -B build
cmake --build build --config Release

Building on MacOS/Linux

cd plugins/<plugin-to-build>
cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build

The resulting binaries can be found under the path:

build/<PLUGIN_NAME>_artefacts/Release/
