AEC frame size
?
hi all,
i am using the Acoustic Echo Cancellation from "Speex 1.1.12 version" in my VOIP application. Is it that the frame length to be chosen should always be 20ms or can i have flexibility in chosing the frame lenght?
on what parameters does the frame length choise depends?
thank you all,
Shri.

Echo canceller problem
...orking great. I compile speex coded for str911 Arm processor.
But I have a big problem with echo canceller from 1.1.12 speex package.
I create echo canceler state:
SpeexEchoState * echo_state = speex_echo_state_init(FRAME_SIZE,
FRAME_SIZE * 5);
FRAME_SIZE is in my project 160 samples. I have 8000ksaples/s, so I must
call echo canceler every 20ms.
and later in the loop I call it:
speex_echo_cancel(echo_state, (short *)Samples, (short
*)SamplesSpeaker, (short *)SamplesOut, NULL);
I give as the parameters to the function the data from tables now.
The problem is when I call speex_echo_cancel it...
