Abstract :
In this article we present a board developed to test algorithms for real-time digital audio signals. Some algorithms have been implemented for the acoustic echo cancellation (AEC). The proposed system can be used during hands free audio conversations in a full-duplex communication. Moreover, the system is able to operate both in personal mode (one to one) and in conference mode (many to many)
