hy,
here is my speex encoder/decoder .. the sampleRate i use is 16000 and
quality,complexity are at 5.
can someone take a look in to the code and see if there is something that is
making that robot voice
here is a link to colored and numbered code, same as below

thanx.

Hi Tim! I haven't looked at your code. I would first make sure that recording and playback of audio is working perfectly without the encoder.
