neuron

Collection of C++ audio DSP components 🧠

Overview

neuron is an open-source DSP (Digital Signal Processing) library that provides a wide-ranging suite of components for building audio software.

It can be used for a variety of applications, including:

• JUCE audio plugins
• Embedded hardware such as the Electrosmith Daisy (see Flora)
• VCV Rack modules

Features

neuron currently lacks wide support for features because it is in early stages, however the following are in its immediate roadmap:

• Dynamics
  • Compressor
  • Limiter
• Effects
  • Chorus
  • Delay
  • Echo
  • Flanger
  • Phaser
  • Reverb
  • Saturation
  • Wavefolding
• Filters
  • LP/HP/BP Filter
  • Ladder Filter
• Modulators
  • ADSR Envelope Generator
  • AHD Envelope Generator
  • Envelope Follower
  • Low-Frequency Oscillator
• Synthesis
  • Amplitude Modulation
  • Frequency Modulation
  • Granular
  • Phase Distortion
• Utilities
  • Clock
  • DC Block
  • Delay Line
  • Sampler
  • Wavetable

Getting Started

Clone this repository:

git clone https://github.com/blackboxaudio/neuron
cd neuron/

Build the library:

make

Using the Library

#include "neuron.h"

// Create a DSP context (sample rate,
// number of channels, buffer size).
static Context context {
    44100,
    1,
    128,
};

// Create an oscillator with an initial
// frequency of 440Hz.
static Oscillator osc(context, 440.0f);

// Write to the buffer with samples
// generated from the oscillator
for(size_t idx = 0; idx < 128; idx++) {
    buffer[idx] = (float)osc.Generate();
}
