a manage to trow out what robot voice, but i can't get rid of nasty
noise. I'll try to replace microphone and i'll see if i get any better
quality out from new microphone.<br><br clear="all">Lp, Tim<br>+--------------------------+<br>| email: <a href="mailto:rico@gama.us">rico@gama.us</a> |<br>| www: <a href="http://gama.us">http://gama.us</a> |<br>

hy,<br><br>here is my speex encoder/decoder .. the sampleRate i use is 16000 and quality,complexity are at 5.<br><br>can someone take a look in to the code and see if there is something that is making that robot voice <br>
<br>here is a link to colored and numbered code, same as below<br><a href="http://barvanjekode.gama.us/temp/1257361243.html" target="_blank">http://barvanjekode.gama.us/temp/1257361243.html</a><br><br>thanx.<br><br>code<br>
