Hi Tom, Thanks for your reply, I'm having a few difficulty's following you advise. You mention that I should be calling 'speex_encoder_int' & 'speex_decoder_int', I'm having problems finding these functions in the speex header. I am currenlty calling speex_encoder_init & speex_decoder_init in my test code, I have repeated the relevent bits of the example bellow. My version of speex is 1.1.6. Thanks once again for your help, David. enc_state = speex_encoder_init(&speex_wb_mode); speex_encoder_ctl(enc_state, SPEEX_SET_QUALITY, &qual...

today I try to compile a test-file from the Documentation. I link the libarys correct but have only one error in this line: state = speex_encoder_init(&speex_nb_mode); The error: main.cpp|21|undefined reference to `speex_nb_mode'| The linking libarys: "libspeex.lib" "libspeexdsp.lib" I am assuming you are doing this in Windows. You need to change the code as follows: //state = speex_encoder_...

...his week, I will also upload the binary builds of static library files to my site www.phonestack.com. I am porting our LTP (lightweight telephony protocol) to some embedded systems. I require to run speex in an environment that doesn't support memory allocations. How difficult is it to convert speex_encoder_init and speex_decoder_init to use preallocated memory buffers (presumably passed by the initilisatio functions themselves)? - farhan - farhan -----Original Message----- From: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] On Behalf Of Gervase Markham Sent: Wednesday, June 28, 2006 2:...

...s. I just upgraded to the latest 1.2beta3 and now I get the following link error: unresolved external symbol speex_wb_mode. Using VS2005. If I put back the old libspeex.lib it compiles just fine, but I would like to upgrade to use the new AEC stuff if I can. My code looks like: enc_state = speex_encoder_init(&speex_wb_mode) ; Worked before the upgrade so did the API change? Any help greatly appreciated.
