Brings Clear HD Voice to Mobile Platforms
Santa Clara, Calif. USA October 16, 2012 Tensilica, Inc. today announced the immediate availability of the AEC WB (acoustic echo cancellation, wideband) technology from IntegrIT DSP Design House, a leading supplier of DSP (digital signal processing) software solutions. The AEC WB codec has been optimized and ported to Tensilicas HiFi Audio/Voice DSP, the leading audio/voice DSP IP core. The IntegrIT AEC WB codec provides off-the-shelf speech enhancement that brings crystal clear HD (high definition) voice to mobile platforms.
AEC WB enables full duplex communications and HD voice (16 Khz) in smartphones as well as intercoms, PC-based video conferencing, and living room environments. It helps make speech much more intelligible with no noise or echo. It suppresses echo even in loud environments with poor speakers and microphones.
Our customers have asked for a G.167 compliant wideband acoustic echo canceller to meet the demand for higher quality speech in smartphones, stated Larry Przywara, Tensilicas senior director of mobile multimedia. Combined with wideband codecs such as AMR-Wideband, this optimized port enables HD voice quality with a small memory footprint and low power.
One of the most cycle-consuming parts of the AEC WB is the FFT (Fast Fourier transform), stated Dmitry Paroshin, managing partner, IntegrIT. We have been very impressed with how effective and precise Tensilicas HiFi DSP can execute the FFT, and other DSP algorithms, in a very efficient manner.
IntegriITs AEC WB codec combines several important customer features. It has a simple integration API (application interface), is robust, does not require any tuning, supports HD mode, and has multiple acoustic profiles. There are several configuration settings available for fine grain tuning, but the AEC WB works perfectly as is on a wide range of environmental conditions with default settings.
The AEC WB codec can be combined with adaptive beam forming software to support up to four microphones, further enhancing the mobile voice experience.
Tensilicas HiFi Audio/Voice DSPs are the leading licensable audio DSP IP cores, licensed by over 50 customers including many of the top 10 semiconductor manufacturers and leading system OEMs. The HiFi Audio/Voice DSPs support over 100 audio/voice codecs and sound enhancement software programs.
