Project title

Guitar SuperPedal

Background

Background: Guitar pedals are connected between the electric guitar and amplifier, altering the output sound through small integrated circuits and analog audio signal processing. The pedals are powered from an external power source and the input from guitar/output to amp travels through quarter inch jacks on the pedal enclosure. Some examples of guitar pedal effects are: Distortion - used for heavy metal music Overdrive - used for solos and light rock Octave - used for bass tones and more!

Description

This project seeks to implement multiple pedal effects, toggled through a switch: instead of buying many single-effect pedals, one enclosure can contain them all! There are printed circuit boards for each pedal effect (ex: high pass filter, op amp) and a mechanism for quickly switching between each pedal. The pedal will be contained within a 3D enclosure. Additionally, the pedal implements a music visualizer on a LED array and analog->MIDI converter.

Deliverable

Create a smartphone app using Google Flutter and Bluetooth communication that allows the user to switch between multiple pedal effects and control the type of pattern on the music visualizer. The interface can display all the guitar pedal effects and LED visualizer pattern, allowing the user to select effect and visualizer pattern. As a stretch feature, write a program (ex: Fast Fourier Transform, Goertzel) for taking in an analog signal and converting it to the MIDI (Musical Instrument Digital Interface) format to be read into a Digital Audio Workstation (DAW).

Skill set desirable

Ability to make smartphone app (Android preferred) Familiarity with signal conversion/algorithms for doing so Communication
