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

Before building the plugins, the JUCE submodule included in this repo must be initialized by running:

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

cmake -B build

cmake --build build --config Release

Building on MacOS/Linux

cmake -B build -DCMAKE_BUILD_TYPE=Release

cmake --build build

The resulting binaries can be found under the path:

build/<PLUGIN_NAME>_artefacts/Release/
