Performance of the acoustic echo canceller
...r why all my posts has no line breaker when it displayed the forum... I used Hotmail(Windows Live Mail)
with FireFox 2.0. I am posting this msg with IE 7.0 and see if it make any difference. Anybody experienced the
same issue and how to workaround it?
Thanks a lot!
Regards,
William

Echo cancellation diagnostic code
Definitely! It tells me that my delay is fine but drifting is -15. I
use the same onboard sound
to record the near end and far end voice. So I can assume it should be fine?
But I don't see the any different between input and output the
echo_canceller function for this recording.
Maybe there is some nonlinearity issue there? The link of this

Performance of the acoustic echo canceller
Hi All, I am working on my master project to port the Speex Acousic Canceller to FPGA. But I am not able to get a satisfied result in its performance whenI integrated it to a SIP softphone as my first step. The SIP softphone calls to a PSTN gateway and lands to my land line phone. I can hear the echo of my every word while I talks on the land line phone. I am using G.711 codec, frame_size 80

question about spx_fft
Hi Jean-Marc and list,
Is the spx_fft function in fftwrap.c a standard fft function?
void spx_fft(void *table, spx_word16_t *in, spx_word16_t *out)
When I say standard, I mean the input "in" is 128 point short data for
example and
the output "out" is 128 short complex value which is stored in 256
short array with real and
image part. Looks like the function did some
