Augmented Reality Audio tools

Augmented Reality Audio is used in many mobile applications like geolocalized games, non- linear audio walking tours, navigation systems for visually impaired people. Different types of navigation will require different types of applications. For example, a mountain biker navigation application will be very different from a guidance application for visually impaired people.

The rendering of an ARA scene can be experimented through the use of bone conduction headsets, headphones with integrated microphones or earphones with acoustically transparent earpieces, with the audio being played by a mobile phone. ARA applications can be designed so that they do not interfere with the user practicing other activies, i.e., the application leaves the user’s hands free and does not require visual attention from the user.

All of the three characteristics of an AR system set different requirements for ARA software and hardware.

A2ML iOS engine for Interactive Audio

This engine implements the version of A2ML which is describe by the following schema.


This engine implements a light interactive version of A2ML which is describe by a RELAX NG schema.

Software Distribution

Our ARA tools can be downloaded from the INRIA Forge .
