...ortunately he has some problems to implement the speex headers. According to the manual "speex_encoder_init" expect a pointer of "speex_nb_mode". Sadly, this constant is not exported by the windows dll (see export table of "libspeex.dll" v1.1.6). Just as extern const SpeexMode speex_nb_mode; extern const SpeexMode speex_wb_mode; extern const SpeexMode *speex_mode_list[SPEEX_NB_MODES]; Unfortunately we could not find any further information or other implemantations of libspeex to solve our problem. regards, Grigory Fishilevich -- NEU +++ DSL Komplett von GMX +++ htt...

Hi I am currently trying to port speex v1.1.6 to a microcontroller with very limited memory (<64Kbyte RAM). what I found when initialising the encoder, a chunk of 32Kb was attempted to be alloced, which failed: src/nb_celp.c: void *nb_encoder_init(const SpeexMode *m) { /* snip */ st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(spx_sig_t)); /* snip */ } same goes for the decoder: void *nb_decoder_init(const SpeexMode *m) { /* snip */ st = (DecState *)speex_alloc(sizeof(DecState)+4000*sizeof(spx_sig_t)); /* snip */ } I tried to...

...am using the speex APIs in a gnuradio block. I used the similar code as in the sampleenc.c/sampledec.c which works perfectly fine. My compilation does not give any error, but when I run the python test, it complains that speex_nb_mode is undefined. I tried to declare it explicitly then it as const SpeexMode *mode = NULL , then i get an error that i cannot initialize the const SpeexMode type. Can someone help me with this problem? Thanks for your time and attention. Regards, Kshama

...In order to use Speex correctly firstly I advice to you examination speexenc and speexdec projects. I have used unsafe code and fixed statements in C#. I have added following method to library and I used that instead of speex_encoder_init simply. void *speex_encoder_init_new(int modeID) { const SpeexMode *mode; mode = speex_lib_get_mode(modeID); return mode->enc_init(mode); } Maybe following codes that I have been using in a class can help you. /* structs */ public struct SpeexBits { char *chars; /* "raw" data */ int nbBits; /* Total number of bits stored in the stream*/ in...

Hi there. I am having a little trouble understanding the frame sizes chosen by the codec. testenc_uwb.c from the speex-1.0 source distribution has a framesize of 640 hardcoded and makes use of this value exclusively. However, a mode query on the actual codec returns 320 as a framesize for this mode. int tmp; speex_mode_query(&speex_uwb_mode, SPEEX_MODE_FRAME_SIZE, &tmp);

As for me - speex_echo_cancellation is a better choise. Try using it in capture thread instead of those speex_echo_capture and speex_echo_playback functions. And please, describe your problem in details. Cause the fact that you "didn get echo cancellation" doesn't mean you are doing smth wrong. Regards, Anton A.

Hi, Guys I am starting looking the source code of Speex. Maybe a little silly, but I can not find the implementation of the function speex_encode(). Only something like below void speex_encode(void *state, float *in, SpeexBits *bits) { (*((SpeexMode**)state))->enc(state, in, bits); } Does that mean some of the detail implementation is embedded in lib without source code? I am new in these Open Source Code project. Thank you for your time. Best regards --- Shanghai Jiaotong University Alumni Email System http://mail.sjtu.edu --- ---...
