Performance and Optimization
...hen I run this on
a Celeron 2,6GHz I have to disable EC in order to not overload the cpu. Am I
correct to assume that there are massive floating point calculations
happening?
I did a quick profile with CodeAnalyst and identified the most expensive
functions as (in order):
CPU Clocks, Function
4657, kiss_fft_stride
4456, speex_echo_cancellation
2494, split_cb_search_shape_sign
1490, fir_mem16
1419, speex_preprocess_run
I'm looking for advise on how to boost the performance with as little code
rewrite as possible. The architecture for release build will be SSE/SSE2
capable.

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
Hello everybody.
I have the same problem like you. I use ARM microcontroller too.
Here is the list of all functions called by speex_echo_cancel until goes
into infinite loop:
speex_echo_cancel()
|
spx_fft
|
kiss_fftr
|
kiss_fft
|
kiss_fft_stride
|
kf_work
Function kf_work looks like:
static void kf_work(kiss_fft_cpx * Fout, const kiss_fft_cpx * f, const
size_t fstride, int in_stride, int * factors, const kiss_fft_cfg st)
{
kiss_fft_cpx * Fout_beg=Fout;
const int p=*factors++; // the radix
const int m=*factors++; // stage...
