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. 1) Compiler optimizations: Reco...

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. -------------- next part -------------- An HTML attachment was scrubbed...

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...
