We are experiencing a few problems with Speex AEC. We are using it to
process audio data on a real time stream over IP with Speex codec (frame
size = 320).
We initialize the echo state like this :
SpeexEchoState * echo_state;
echo_state = speex_echo_state_init(320,512);
int sr = 16000;
We are not really sure about the values in parameters, please tell us if
you see something wrong about them.
we process the data like this :
the output stream is almost the same as the input one, meaning there is
not a really efficient echo cancellation when we use this.
What do you think could go wrong here?
PS : we are using Speex 1.2 RC1
We're looking forward to hearing from you.
