Hi all, i use speex preprocessor features in this way: =================================== #define NN 160 /* 20msec di audio */ ... int tbc=0,c,d,ret; spx_int16_t TEMP_Buffer[NN]; char DLECODE; /* Inizializza il preprocessore Speex se non inizializzato */ if(Modem->speex_pp_state == NULL) { Modem->speex_pp_state = speex_preprocess_state_init(NN,AUDIO_SAMPLERATE); } /* Modifica i parametri di Speex */ c = Modem->denoise; speex_prep...

Hi all, as in subject, speex_preprocess inject noise in my data. Someone can help ? Here's the way that i'm using: #define NN 160 /* 20msec di audio */ #define AUDIO_SAMPLERATE 8000 spx_int16_t TEMP_Buffer[NN]; speex_pp_state = speex_preprocess_state_init(NN,AUDIO_SAMPLERATE); c = denoise; speex_preprocess_ctl(speex_pp_state, SPEEX_PREPROCESS_SET_DENOISE,&c); c = agc; speex_preprocess_ctl(speex_pp_state, SPEEX_PREPROCESS_SET_AGC, &c); if(agc) { float t; t = agc_level * 3276; speex_preproces...

...rray. Here are my first steps but it don´t work and i don´t come forward. Hopefully someone can help me! CALL int __stdcall EncodeSpeexFrame (float *input_frame, unsigned char *output_bytes, int input_size) { int MAX_NB_BYTES, nbBytes; char *output_buffer; unsigned char *temp_buffer; float *input_buffer; input_buffer = new float (input_size); input_buffer = input_frame; speex_bits_reset(&enc_bits); speex_encode(enc_state, input_buffer, &enc_bits); delete input_buffer; MAX_NB_BYTES = speex_bits_nbytes(&...

...ov_raw_tell() and ov_raw_seek() because the documentation says they are the best when speed is a concern. but the problem is that sometimes ov_raw_tell returns the same value before and after calling ov_read; here's an example: prevPos = ov_raw_tell(&vf); const long ret = ov_read(&vf, temp_buffer, 4096, 0, bytesPerSample, 1, &current_section); currentPos = ov_raw_tell(&vf); now, if I check, I'll find that prevPos == currentPos, how could this be true?? I tried the other seeking methods, which are time and pcm, and none of the did the same, prevPos is never equal to currentPos...
