? 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...

Hi, I am new to speex so please redirect me to some links if the question is repetative. Just for testing the echo canceller performance, I have added mdf,fftwrap,misc,kiss_fftr,kiss_fft source files to my project. Now In my multithread application when I receive packets from mice, I calls speex_echo_capture(echo_state, input_frame, output_frame,Youtput_frame) with input_frame as data received from mice(160 bytes as I am using G711 codec) and I send data out receiv...

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 co...

...ncel function is called or not. Let me first give more details about what I'm doing. Since I'm only interested in AEC (we use a simple a-Law for the audio compression), I created a lib that only includes the following files, all from directory \trunk\speex\libspeex: fftwrap.c kiss_fft.c kiss_fftr.c math_approx.c mdf.c misc.c This appears to be sufficient to call the speex_echo_* functions without a linker error. I define the preprocessor symbols CONFIG_TI_C6X and HAVE_CONFIG_H. FIXED_POINT is defined in ti/config.h (also from the trunk). I am using the latest files from svn, as of last Thu...

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
