Hi folks.
My first post over here.
While working on a music server optimzation (which ususally goes hand in
hand with running pretty low buffers on realtime
streams)
I figured that certain HiRez flacs were causing XRUNS/hickups on my Linux
server platform.
The interesting thing is to run into XRUNS even though the stream gets

a 20s buffer on its receiving end.
However. Even a potentially short break of that flac decoding stream seems
to cause a probl...

What is a HiRez flac? How does it differ from a regular flac?

Even better! :-)
