Adaptive Digital's wideband acoustic echo cancellation algorithm also supports narrowband. This acoustic echo canceller is the fourth generation (G4) acoustic echo canceller offered by Adaptive Digital.
The Adaptive Digital Technologies acoustic echo canceller (AEC) electronically removes both direct coupling and reflected echo, enabling true full-duplex hands-free telephony in mobile phones, speakerphones, and hands-free intercoms.
The fourth-generation canceller includes a noise reduction feature, as well as the typical anti-howling, nonlinear processing, and double-talk detection found in the first generation AEC. The acoustic noise reduction feature is particularly useful during speakerphone calls where there is background noise present such as an exhaust fan, and in noisy outdoor environments.
Feature unique to AEC Gen 4:
Supported by ARM processor-based devices
