AEC stops working in 1.2-rc1?
...00 samples). *And*, in addition to
that, I delay the frames that's fed to speex_echo_cancellation() by 100ms,
to reflect the playback/recording delay when the mic.pcm file was recorded.
This means, if I play the frame now, I will give it to
speec_echo_cancellation() 100ms later (similar to your PLAYBACK_DELAY in
mdf.c). So this is equal to shifting the blue signal in your graph to the
right by 100ms.
It's easier to understand with testecho perhaps. I did the following changes
to testecho.c:
- changed the frame size and tail length:
#define NN 80
#define TAIL 1600
- apply the delay before...

Reseting Echo State
Hello guys,
I want to make echo tail parameter in my app changeable during run-time.
So my question is:f
Should I use speex_echo_state_reset function for this? Just call
speex_echo_state_init function with new values after that?
Or perform a full de-initialization and initialize echo cancellation
with new tail value?
I'm also using preprocessor - does the same apply to it?

Thanks for the help. The files are on their way now, the upload will take
few more minutes to complete. In the mean time let me explain more
