Kane Offers for Mobile Telephony Acoustic Echo Cancellation

7/28/2003 - Kane Computing has broadened its advanced Acoustic Echo cancellation product portfolio with Mobile Acoustic Echo Cancellation software solution designed to seamlessly work in mobile devices. The software is a highly integrated solution with such features as echo cancellation, noise cancellation and narrow signal protection.

Mobile Acoustic Echo cancellation software by SPIRIT is focused on the mobile telephony devices, embracing cellular phones, hands-free mobile sets, car-kits and smart-phone devices.

Wireless mobile echo presents new challenges beyond telephony and Internet telephony issues that have been successfully overcome by SPIRITís echo suppressing technology.

People are going increasingly mobile, using small, portable devices to communicate, and are looking for improved quality of their communication. Requirements to sound clarity make acoustic echo cancellation more critical than ever as one of fundamental factors influencing communication quality.

Not less important is growing tendency to avoid the harmful microwave influence of mobile phone closely pressed to the head, which leads to broad use of hands-free devices and high demand for echo free speech quality.

Dramatic improvement in sound quality is achieved through a combination of techniques including sophisticated full-duplex control, high robustness to the specifics of mobile equipment, such as noise and non-linear distortions, reliable double-talk detector, enhanced non-linear processing and sub-band processing and adaptive filtering.

The software is distinguished by such features as: True full-duplex speakerphone operation, More than -42dB total echo rejection, Fast convergence, Dynamic adaptation to changing conditions such as noise, speech levels, or delay.

Acoustic Echo cancellation software has a proven track record, being integrated in the leading European videophone and e-mailer products.

A working version of Mobile Acoustic Echo Cancellation software is offered in two modifications, written as fixed-point DSP code, and is readily ported to multiple DSP or RISC architectures, such as Texas Instruments C54x, C55x, ARM7/9/strong ARM/xscale/Calm16.
