Second, said sound field must be translated into a pair of sound pressure signals at the user's ears. First, room acoustics must be simulated accurately to predict the reverberant sound field produced by the virtual source as sound wavefronts reach the user. A successful AAR system should create the illusion that virtual sounds actually come from the user's environment, for which several technical challenges must be overcome. The proposed digital ARA system enables several immersive audio applications, such as a virtual audio tourist guide and audio teleconferencing.Īudio Augmented Reality (AAR) is defined as the extension of a real auditory environment through virtual sound sources. Insert ARA headphones have a sufficient attenuation at frequencies above about 1 kHz. The comb filter effect in speech and music signals was studied in a listening test and it was found to be inaudible when the attenuation is 20 dB. When the direct and processed sounds are combined in the ear, a comb filtering effect is brought about and appears as notches in the frequency response. Measurements show that the throughput latency of the digital prototype ARA system can be less than 1.4 ms, which is sufficiently small in practice. This paper proposes digital IIR filters to realize the required equalization and evaluates a real-time prototype ARA system. A practical implementation of an ARA mixer requires a low-latency headphone reproduction system with additional equalization to compensate for the attenuation and the modified ear canal resonances caused by the headphones. Ideally, the ARA headset should be acoustically transparent, that is, it should not cause audible modification to the surrounding sound. An ARA system can be realized with a headset containing binaural microphones.
