[Speex-dev] Speex sound a little artificial?

[Jean-Marc Valin]

Hi,

This applies to everyone having (or suspecting) problems with Speex. The
first thing to do is to encode the file in wav format and use
speexenc/speexdec on it. If you're getting something different with your
application, it's likely buggy. If the result isn't OK, then it can be:
1) Normal given the bandwidth/bit-rate used
2) A conditioning problem with your audio (i.e. DC not removed)
3) A bug in Speex (quite rare at this point)
