kabruzzo – Project 1 – Audio Signal Processing With Sensors

For my first individual project, I decided to work with Arduino because I really enjoyed the videos shared on Slack on interactive sound installations. I also have worked with Arduino before, and thought it was cool that you could have it output to Max. I decided to work with flex sensors because I haven’t worked with type of sensor before and thought it was interesting. I also use a potentiometer.

I used a feedback system to create an echo. One of flex sensors pitch-shifts the echo, another one sets the delay of the echo, and the last one sets the volume for the echo. There’s also a degrade that goes from a resolution of 0 bits to 10 bits, then back from 10 bits to 0 bits in a loop. The rate at which the resolution changes is set by the potentiometer.
