Abstract

In Augmented Reality Audio (ARA) applications the real sound environment of the user is extended with
virtual ob jects. The real environment is reproduced as a pseudo-acoustic world via a special ARA headset
that consists of binaural microphones and headphones. However, the headset causes coloration to the pseudo-
acoustic representation. In order to make the headset acoustically transparent, equalization is needed. Digital
equalization easily causes unacceptable delays. This paper presents a novel ARA mixer with real-time analog
equalization to correct the coloration caused by the leakage through the headset and changed resonances in
the closed ear canal.
