Hello! I am downloaded last version of speex library and did compile DLL. But I am have not good sound : Please see my code (Delphi) and say me please WHat I am do not right. Or please send me correct compiled DLL and example of correct using SPEEX_MODEID_WB and SPEEX_MODEID_UWB , denoise, and other effects. How I can set MONO mode in decode? My Code: smpRt:=32000; n:=10; encbits: TSpeexBits; encstate: Pointer; encframe: integer; decbits: TSpeexBits; decstate: Pointer; decframe: integer; buffEnc: array of single; buffDec:...

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.

Try to use "speex_lib_get_mode(SPEEX_MODEID_WB)" call instead of using "speex_wb_mode" directly in your code. MS is tricky about exporting variables from DLLs. -- Regards, Alexander Chemeris.

Hi, I'm trying to use speex codec in iax client to connect to asterisk (all last version) It seems that when I use speex_encoder_init(speex_lib_get_mode(SPEEX_MODEID_WB)) Instead of speex_encoder_init(speex_lib_get_mode(SPEEX_MODEID_NB)) Asterisk try to downscale the codec to ulaw.

Hi all, I am a newbie here and just started using speex in our lab. During compiling my voice application with windows-compiled version provided today, I am getting "unresolved external symbol _speex_wb_mode". I am probably missing some setting with VS6.0 linker... (I am a bit new to windows too) If anyone could point it out, I would appreciate it. - Tim -----Original Message-----
