PedalJUCE

Date: May 2025 - Ongoing

Description: PedalJUCE is a JUCE-powered digital guitar pedal emulator VST and standalone application. The goal of this project is to provide users with a free library of common guitar pedal effects that can be used in live performance scenarios.

Desired features:

• GUI workspace for connecting and modifying pedals, including their parameters (e.g., tone knobs)
• Diverse collection of pedal modules, including classic guitar effects pedals (e.g., distortion, tremolo) and new effects made possible via DSP (e.g., convolution)
• Preset system for both pedals and pedal arrangements
• Control via external devices and a context selection system (e.g., MIDI knobs control a selected pedal knob)
• Simple stereo IO system that hooks into and interacts with system IO
• Low latency processing
• Support for deployment into a Raspberry Pi system for live performance use
• Application for constructing and generating GUI code for pedals graphically

converb~

Date: February - May 2025

Description: converb~ is an unpartitioned convolution reverb external for Pure Data coded in C. This project was created as part of my capstone presentation for my undergrad at UIUC.

Features:

• Convolves input signals with a fixed-length impulse response (read using tabread~)
• Uses windowing to minimize clicks created from convolution
• Uses estimated FFTs from the FFTW3 library to efficiently perform convolution in pseudo real time
• Detailed help file (converb~-help.pd) that explains how to use converb~

Areas for improvement:

• Use partitioning to reduce IR delay
• Use a more sophisticated vector multiplication algorithm to speed up the convolution step. This could consist of SIMD and/or alignment tricks in C
• Investigate if FFTW plans can be saved and reused in the object proper
