An Analog Audio Sensor Board for Microcontrollers

This paper presents work on the Audio Sensor Board (ASB), a circuit board designed to serve as an analog interface between audio signals and the digital/analog inputs of common micro-controllers. The ASB allows for low-level manipulation of audio signals so that those signals can be easily used as control parameters, in essence creating a two-channel analog/digital sensor for sound sources. In this paper we layout the various functions of the board, its design, and describe practical purposes for which it has successfully been used.
