...tive enough to save everyone some time. If I'm off with this one please forgive me, but it has fixed my issues. I am not sure whether it is just my compiler (gcc 3.3.5) doing the wrong thing with the cast. File: preprocess.c Arch affected: x86, (others?) svn revision: 12778 Description: The SpeexPreprocessState_ member 'nb_adapt' is a signed integer. nb_adapt is only modified during 'speex_preprocess_run' when an unbounded increment is performed. When calculating 'beta' within 'speex_preprocess_run', I received a floating point exception even when compiled with -DFIXED_POINT...

...r); but how do I know if the frame contained voice? I tried if (preprocess_state->was_voice == 1) { ...Do voice present code... } But the compiler complains that was_voice is not defined, which, I assume, comes from the fact that preprocess_state is declared in speech_preprocess.h as struct SpeexPreprocessState_; How do I check the preprocessor for the presence of voice in a frame? Thanks, Evgueni

...there is enough speech to consider AAGC and then loudness2 to decide how to adjust the input mixer. We want to use the latest speex, for echo cancellation and other reasons, so I tried just making SpeexPreprocessState visible again, but it turns out neither of these members are present in the new SpeexPreprocessState_ structure anyway. I was able to re-create the speech_prob member by setting it from Pframe before speex_preprocess_run returns, and I've used agc_gain as the basis for adjusting the mixer (i.e. if agc_gain is high, the input is low, so turn the mixer up and v.v.). This appears to be effective....

hi guys, i am trying to develop an application having a capability to detect voice activity in voice stream and then record only portion of this stream which contains the activity. i went through these steps. 1. Captured voice through Waveform Functions of Windows Multimedia API 2. Started Speex Preprocessing liberary 3. Turned on preprocessor by calling speex_preprocess_state_init and

...ex_preprocess_state_init has lots of pointers that are initialize with static inline void *speex_alloc (int size). So I am trying to convert all this pointers into arrays but it is getting messy trying to found out how big they need to be, and not sure if it will work. And it is not only the struct SpeexPreprocessState_ that has lots of pointers there are other structures with pointers too. So I am trying to replace this pointers with arrays. This is what I am doing but not sure if it is correct: spx_word16_t *frame; converted to: spx_word16_t frame[2*N]; st-> frame = (spx_word16_t *)speex_alloc(2*N*sizeof(s...
