...h I can clearly recognize what was said and the encode and decode functions go through without any errors. I bypassed the speex functions and just sent uncompressed PCM using the same app and its crystal clear. Where am I going wrong here? Anyone got any suggestions? My code is as follows #define AUDIO_QUALITY 10 #define FRAME_SIZE 160 #define COMP_FRAME_SIZE 62 char *encodeSpeexWithBuffer(spx_int16_t *buffer, int *insize) { SpeexBits bits; void *enc_state; char *outputBuffer = (char *)malloc(COMP_FRAME_SIZE); speex_bits_init(&bits); enc_state = speex_encoder_init...

Hi everyone, I'm trying to encode/decode with speex, when I do not, the audio is loud and clear, but when I encode/decode to test audio quality, I get a really poor audio quality and a robotic sound. Here's my init audio method : #define AUDIO_QUALITY 10 - (void) initAudio { try { //SPEEX CONFIG speex_bits_init(&bits_in); speex_bits_init(&bits_out); enc_state = speex_encoder_init(&speex_nb_mode); dec_state = speex_decoder_init(&speex_nb_mode);...
