Product Description

HD Software Acoustic Echo Canceller: HD AEC

HIGH DEFINITION ACOUSTIC ECHO CANCELATION

Adaptive Digital’s High Definition (HD) Acoustic Echo Canceller (AEC) was designed for the next generation product. Target applications include, but are not limited to, the following: conference speakerphone, desk phone, hands-free wireless, mobile handset, and intercom systems.

HD AEC Varients

Single microphone (standard), multi-microphone and dual-microphone with noise reduction. Single-microphone is used in most applications. Multi-microphone is used in applications such as high-end conference phones that make use of multiple microphones that are placed around conference room table. Dual-microphone with noise reduction is used in devices that have a primary microphone to capture speech and a secondary microphone that is used to measure background noise.

Enhanced Full Duplex Operation

The single most important feature when evaluating AEC is full-duplex performance. Adaptive Digital’s HD AEC provides true full duplex under a wide set of difficult acoustic environments.

Even in challenging conditions such as unbalanced speech levels, close speaker to mic proximity, background noise, double talk, and echo path changes, AEC HD achieves good full-duplex performance.
