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);

...written with C#. 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...

...ng: Trying to encode in %s at %d Hz. I'll do it but I suggest you try ultra-wideband instead\n", mode->modeName , rate); causes this segmentation fault, because commenting it out (you find the line in speexenc.c after the check if it's a wav-file, if you follow the conditions: if (modeID!=-1 && rate), if (rate>25000), if (modeID != SPEEX_MODEID_UWB)) makes the encoding run through. Does anybody else have this problem? Or is that just my computer? Thanks, Bj?rn -- Important! Please recognize my new GPG Public Key! Bj?rn Thalheim gpg fingerprint: 0A29...

I could not figure out how to use speexdec.exe 1.2.3 in piped mode in order to avoid the creation of the potentially large intermediate *.wav or *.pcm files. Any
