Forward error correction implies extra latency, so of course it has to make up for enough packet loss to provide a net reduction in latency to be useful.<p>Is there a generic UDP-based FEC transport library that one could use to wrap a simple Opus or FLAC stream and test this out?  <i>Edit: I found <a href="http:&#x2F;&#x2F;openfec.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;openfec.org&#x2F;</a> but it seems to implement something other than packet loss recovery</i>
