.... How do I get rid of this noise? The code is as follows. For encoding . state = speex_encoder_init ( &speex_nb_mode ); tmp = 7; speex_encoder_ctl ( state, SPEEX_SET_MODE, &tmp); // set quality tmp = 10; speex_encoder_ctl ( state, SPEEX_SET_QUALITY, &tmp); // initialize bits speex_bits_init(&bits); while( 1 ) { // read FRAME_SIZE bytes from buffer // convert to short for ( int i = 0; i < FRAME_SIZE; i++) in[i] = out_buffer[i]; speex_bits_reset(&bits); // encode speex_encode ( state, in, &bits); // copy bits...

...unsuccessful debugging attempts I went back to the older version that has been very solid for me. I'm pretty sure the problem is on my end but I haven't figured it out yet... I thought it might be related to packing multiple frames together. Can you tell me if it's still ok to do speex_bits_init, call speex_encode several times, then speex_bits_insert_terminator, then speex_bits_write + speex_bits_destroy. And then on the decoding side do speex_bits_init, speex_bits_read_from, and loop on speex_decode until either it returns -1 or speex_bits_remaining returns <= 0? > If you sti...
