Raspberry Pi Audio Looper in C

Welcome to my Raspberry Pi Audio Looper project. A few years ago I wondered what I could do with my many Raspberry Pis. A few years before that I saw someone masterfully work a BOSS Loop Station and create some amazing live music, with just one person! I have often wanted to do that myself.

Getting Started

I have created instructions on how to setup the Raspberry Pi for audio setup. Rather than duplicate the postings here, I am linking to them in the Instruction Pages section of this page. I broke it out into three sections because they are quite detailed and do take quite a bit of time to get through.

Prerequisites

For this project you will need:

A Raspberry Pi 2 with an SD card installed, running Raspbian 
A USB audio interface, such as Berringer UCA222 which is what I used
A USB to TTL serial port adapter to connect to the Pi via the UART

Instruction Pages

• Overview - The high level discussion and motivation for the project
• System Setup - Setup instructions for required supporting software
• Audio Looper Setup - Setup instructions for the Audio Looper and a list of commands
• Audio Looper Design - An explanation of the current design of the Audio Looper

Acknowledgments

• Special thank you to the Jack Audio guys for making this project simpler, by creating Jack
• Thank you to David Frey for expressing interest and contributing ideas to the design, his interest alone was a strong motivational force
• My family for putting up with my obsessiveness while working on this project
