2008-10-01 16:46:34     Acoustic Echo Cancellation or VOX?

I have a vague memory the blackfin devs were working on a software solution for acoustic echo cancellation (AEC) or a VOX (half duplex) mode that could be used with an applications like linphone. 

 

Has there been any progress on this front?

I think there were some recent (months ago) tweaks to the AEC in speex & driver that makes it mostly useable.

 

There was someone making some modifications to the AEC which made it into a VOX - but I don't know how widely tested it was. (or how far they got, or if they were planning on releasing it - I will ask and get back to you).
