Abstract

Acoustic Distributed Sensors (ADS) are widely used for the gathering of acoustic information dedicated to the research of urban planning, environmental control, and public security. The emergence of new algorithms of computational low cost and computing devices more small, economic and affordable, has created the possibility of developing a low-cost acoustic sensor that can be deployed in an Acoustic Sensor Network (ASN). In this work, the design and development of a multichannel audio acquisition device based on Raspberry Pi are described. This device can be used as a node of an ASN. For the development of the software that is executed in the Raspberry Pi, the programming language Python was used, being obtained a library of functions that allows the work with several audio cards in a simultaneous way. The made tests have shown the Raspberry Pi as a powerful and affordable computing core for ASN’s node.
