JUCE module with utilities for ChowDSP

chowdsp_utils

This repository contains JUCE modules with utilities for building Chowdhury DSP plugins.

There are currently 3 modules each containing the following utilities:

• chowdsp_dsp
  • Convolution: Helpful classes and methods for working with IRs and real-time convolution
  • Delay Line: similar to juce::dsp::DelayLine but with 5th-order Lagrange interpolation and Sinc interpolation.
  • Pitch Shifter: using a ring buffer with two read pointers.
  • Filters: functions for bilinear transform, IIR filters with static order, and an optimized State Variable Filter.
  • Modal: modal filter/oscillator using Max Mathews Phasor Filter.
  • Sources: "magic circle" sine wave oscillator, anti-aliased saw and square oscilaltors, noise generator.
  • Resampling: classes for doing integer or non-integer sample rate conversion, and processing audio at a target sample rate.
  • Wave Digital Filters: linear circuit elements, series/parallel junctions, diodes, R-Type adaptors, and a few others.
  • SIMD Utils: Some extensions on juce::dsp::SIMDRegister.
  • A few other odds and ends.
• chowdsp_gui
  • Custom LookAndFeel.
  • Helper class for optionally using OpenGL.
  • Helper classes for working with long-presses and popup menus on touch screens.
  • Custom tooltip viewer.
  • Component to display plugin info (version, format, etc.).
  • Component for controlling preset management.
  • Interfaces with Plugin GUI Magic (a slightly older version).
• chowdsp_plugin_utils
  • Base class for audio effect plugin.
  • Base class for synth plugin.
  • Utility class for managing plugin presets.
  • Utility functions for creating parameter layouts.
  • Utility class for "forwarding" parameters from one processor to another.
  • Shared resource class for managing LookAndFeel allocation.
  • Shared resource class for managing global plugin settings.
  • JUCE-based Wrapper around nlohmann::json.
  • Thread class for running a task that reads from the audio thread, and reports info to the UI thread.

For complete documentation, see the API docs.

Usage

If you are using JUCE with CMake, simply add this repository as a subdirectory after adding JUCE to your CMake project.

add_subdirectory(JUCE)
add_subdirectory(chowdsp_utils)

target_link_libraries(MyTarget PUBLIC
    juce::juce_audio_utils
    juce::juce_dsp
    # other JUCE libraries...
    chowdsp_dsp
    chowdsp_gui
    chowdsp_plugin_utils
)

Alternatively, you may add these modules from the repository directory from the Projucer.
