A DIY ATTiny44 based guitar preamp+effector. All the audio processing is done digitally on-board. So it is definitely not a HiFi system, but something you can definitely have fun programming. You can program the audio properties in Arduino IDE and create mobile apps that talk to the module for remotely controlling the effects. […]

Introduction “A device that pitch-shifts voice in real time” For our final project, we attempted to implemented a real-time vocal pitch shifter. The system was designed to work as follows: a user speaks into a microphone, their vocals are processed using a pitch shifting algorithm, and the resulting signal is output through speakers. All of

Introduction For our ECE 4760 final project, we designed and built an array of 12 independently-controllable speakers to implement an acoustic phased-array system. The system samples a standard audio input signal at approximately 44.1 kHz, and then outputs this signal to each of 12 speakers, each with a variable delay. The idea behind a phased-array
