chowdsp_utils

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

There are currently 3 modules each containing the following classes:

• chowdsp_dsp
  • 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, noise generator.
  • Resampling: classes for doing non-integer sample rate conversion, and processing audio at a target sample rate.
  • Wave Digital Filters: linear circuit elements, series/parallel junctions, diodes, and a few others.
  • Some extra functions and classes for SIMD operations.
• chowdsp_gui
  • Custom LookAndFeel.
  • Utility class for managing LookAndFeel allocation.
  • Custom tooltip viewer.
  • Component to display plugin info (version, format, etc.).
  • Component for controlling preset management.
• 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.

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.
