...ks great, but then it begings to gain lag, and in a little time it has 5-10 lag seconds (into the same machine, working on loopback). Currently I'm packaging 4 frames per package (FRAMES_PACKET=4). Any help will be greatly appreciated. Into the encoder I have this code: speex_bits_reset(&enc_bits); for(int i=0;i<FRAMES_PACKET;i++) { int nb_samples; //Here I get the microphone data. while((nb_samples=Check_Mic(Mic_data))==0); speex_encode_int(enc_state, Mic_data, &enc_bits); total_samples += nb_samples; speex_bits_insert_terminator(&enc_bits); //The...

The stream is not corrupted but i wish to know what those warning mean to correct my code.

...every frame inside the packet? And how can I get the number of bytes speex_decode_int() wrote into the destination buffer? Here small code snippets of my implementation: //********************************************** // Encoding: short* Frame = (short*)malloc(speex_frame_size); speex_bits_reset(enc_bits); for(unsigned int i = 0; RecBufferLen > speex_frame_size * i; i++) { memcpy(Frame, RecBuffer + speex_frame_size * i, speex_frame_size); speex_encode_int(enc_state, Frame, enc_bits); } free((void*)Frame); return speex_bits_write(enc_bits, SendBuffer, SendBufferLen); //**********************...

Thanks for your reply. I changed my code to: if (speex_preprocess_run(preprocess_state, shortPointer) == 1) { speex_encode_int(enc_state, shortPointer, &enc_bits); } In the mobile version of the software, compiled against the mobile build of Speech, I get 1 and 0 based on whether the speech is detected. In the version of the software compiled against the Win32 version of Speex, speex_preprocess_run always returns 0. If I remove the IF statement, then I ge...

This must be a simple issue, but I cannot figure it out. I want to use VAD, but I don't know how to check if the actual frame has voice in it or not. So, in my code, I do: int tmp = 1; speex_preprocess_ctl(preprocess_state, SPEEX_PREPROCESS_SET_VAD, &tmp); speex_preprocess_ctl(preprocess_state, SPEEX_PREPROCESS_SET_DENOISE, &tmp); then later, for each frame
