Locative Audio and Augmented Reality

We geo-tag images and text all the time so way not do the same with sound? Echoes is a platform that lets you attached audio to physical locations. These areas then act as geofences and trigger content when your listeners physically walk inside. In this way the listener controls the experience by physically moving through an area. In this interview with Josh from Echoes we also discuss 3D audio as a way of augmenting reality.
