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.
