Indoor and outdoor environmental data: A dataset with acoustic data acquired by the microphone embedded on mobile devices.

ABSTRACT: All mobile devices include a microphone that can be used for acoustic data acquisition. This article presents a dataset of acoustic signals related to nine environments, captured with a microphone embedded on off-the-shelf mobile devices. The mobile phone can be placed in the pants pockets, in a wristband, over the bedside table, on a table, or on other furniture.
