Research on VoIP Acoustic Echo Cancelation Algorithm Based on Speex
Abstract: Echo cancellation
has been a major problem to be solved in VoIP, although the integrated echo cancellation
module in Speex, it does not consider thread synchronization issues. The
frequency domain echo cancellation algorithm MDF of speex is analyzed, and then
a synchronization method of playing thread and recording thread is proposed.
The results show that the acoustic echo canceller which achieved by the
proposed method meet the requirements of voice communication, implementation is
easier and therefore provides a reference for the VoIP voice communication and
mobile communication terminal.
