Hi Jean-Marc, I used the following code after init of the encoder to get the frame size of my RTP packets. char pcm_data[3200]; char speex_data[3200]; SpeexBits bits; memset(pcm_data, '\0', 3200); memset(speex_data, '\0', 3200); speex_bits_init(&bits); speex_bits_reset(&bits); speex_encode_int(codec_info->enc,

Hello! I'm getting SING errors from the log() function. Here is the code inside the vbr_analysis() function. if (ener<60000) { if (vbr->consec_noise>2) qual-=0.5*(log(3.0 + vbr->consec_noise)-log(3)); if (ener<10000&&vbr->consec_noise>2) qual-=0.5*(log(3.0 + vbr->consec_noise)-log(3)); if (qual<0) qual=0;...

So yes, there's a lot of stuff you can remove. You can also get rid of the stereo preprocess, mdf files. You can also remove the VBR part of the narrowband encoder and the vocoder part of t...
