NTT DoCoMo announces new spatial audio transmission technology for mobiles
NTT DoCoMo, Japan’s largest mobile carrier, announced the development of a new and efficient mobile spatial audio transmission technology that should improve applications related to mobile conference calls, online games and tele-education.
According to the company, the new technology allows “a user listening with headphones to, for example, hear each speaker’s voice as if it were coming from a unique direction, creating a virtual face-to-face communication environment.”
Unlike other spatial audio transmission technologies, which process audio encoding/decoding and spatial audio synthesis independently, DoCoMo’s technology integrates the two processes. This way, the bitrate (bandwidth) is minimized, making the processed audio content suitable for resource-limited devices such as cell phones.
NTT DoCoMo said it would demonstrate the spatial audio transmission technology during Wireless Technology Park 2009 at Pacifico Yokohama (12 –13 May), on the DoCoMo Pro HT-01A handset – which is, in fact, the Japanese edition of HTC Touch Pro.
