3-D Audio IP Business for Wireless Phones

26th April , 2004

ASIA : FueTrek licenses from Matsushita Electric Semiconductor Company the 3-D audio technology, and expands sales of this high-end 3-D Audio IP capable of creating the feeling of being at live performance worldwide.

Inset shows FueTrek HQ at Osaka,Japan.

Integration of Sound Generator IP and 3-D Audio IP owned by FueTrek will bring a new dimension to the market of sound generator for mobile phones. With the 3-D Audio, realization of the stereo sound expanding sound field and the freely movable sound image makes it possible for the stereoscopic sound reproduction. Globalizing ringtone service and mobile games will be enriched and more entertaining, which leads to the creation of new content services. Fast-paced popularization of 3-D Audio in the market of mobile phone is expected and promising.

3D Sound IP
Features
1.Rich Sound Effect Utilizing the Characteristics of Space Between Sound Generator and Ears
With the technique of calculating pure sound characteristics between sound generator and ear (called HRTF), it is possible to obtain accurate localization of sound even drastically reducing the total size of 3-D audio coefficients expressing HRTF.

2.Low Power Consumption
Low power consumption, absolutely indispensable for mobile phones, is achieved by reducing the total size of 3-D audio coefficients expressing HRTF.

3.Calculation of HRTF Corresponding to Reflected Sound Reproduces and Radiates 3-D Audio
Calculating HRTF corresponding to reflected sound in all direction as in studio and halls can express more dynamic and natural sound just as in the live performance.

4.Offering as IPiIntellectual propertyj
By offering 3-D Audio as an IP, it can best suit the design policies of licensees when mounting on system LSI or stand-alone LSI.

5.Providing API Source Code
API (Application Program Interface) source code is provided in order for licensees to reduce the workload on software development.

6.Providing Optimizing Design Tool for 3-D Audio Coefficients
Design tool for adjusting 3-D audio coefficients is provided for optimization of effect in accordance with the acoustical design of mobile phones.
