Hi, speex developers!
I'm new to speex, and trying to build a simple echo application.
something like this.
microphone -> speex encoder -> speex decoder -> speaker
I first test it the simple way,
microphone -> do nothing -> speaker
and this works fine.
But when I try to encode speex, and decode it,
it works, but some high frequency noise is added.
How can I fix it?
The noise isn't the microphone <-> speaker positive feedback,
cause it doesn't appear when not using speex.
I think it's almost the same as your
testenc_uwb.c included in speex distribution,
but mine maybe something wrong...
Source code is here.
and Windows binaries here.
There's a switch to enable speex in main.cpp
Thanks in advance!
