[Speex-dev] Extracting Coefficients from the AEC

Tue Jul 26 15:17:27 PDT 2011

Hello,

I am new to this forum and have done my best to search for my answer before emailing, but have been unsuccessful. I have an application where I would like to utilize the speex AEC library for canceling hybrid echo. I thought it would be useful to save the coefficients of the filter for reuse, especially since the characteristics of the echo path will not vary. The specific application for the hybrid scenario consists of a "side-tone" producing device (e.g. radio) connected to a full-duplex interface which connects to a digital voice network. It isn't a show stopper if this in not a capability, but in the event my system or software was reset, it would be nice to not have to reconverge every time (i.e. intialize the adaptive filter to a non-zero state).

Thanks in advance!

Doug C.
