Abstract/Artist Statement
The purpose of this project is to create a guitar pedal that records audio signals, and then plays back that same signal. The Audio Loop Pedal is designed to take in up to 14 seconds of audio and store up to 200 different audio samples. These samples to be played independent of incoming audio at discretion of the user. The pedal is controlled by two stomp switches. The overall design should be easy to use. One stomp switch controls record starts and stops. The other pauses or plays. Both at the same time will clear the signals in memory. The constraints are that the case be ordered from a singular manufacturer but still within the ambitious goal of a $50 dollar pedal. A single loop is 1mb while the ram of the Raspberry Pi Zero is 512mb the adc will sample at 50 khz our pedal is able to sample at 150 Ghz. The design incorporates a sallen key filter for loop volume and high and low pass filters.
