Very basic question from someone just getting set up. I've read that
some can hear differences in FLAC vs. WAV streamed, but not when
alternatively stored on the server. Are these two different ways of
configuring SB? Streamed vs Stored? How would one play Flac that is
stored on the server? Is
You missunderstand the argument.
All music is streamed to the SqueezeBox, it has no local storage beyond
a small playback buffer.
The argument is whether FLAC sent directly to the SB sounds different
to the same file being de-compressed to it;s original WAV and that
streamed to the SB.

Maybe the difference being compared is who provides the clock. When
non-sync, locally stored music is played, the Squeezebox or Transporter
provides the clock reference and requests data from Slimserver as it
needs it. When multiple units are playing in sync and for most
Internet radio, the
er...no.
The transfer of data from PC to SB has nothing to do with the clocking
of the DAC!
There is no ASRC going on AFAIK. The SB always provides the clock.
The SB supplies data to the DAC/SPDIF via its internal buffer. The PC
sends data into the buffer. The buffer does what a buffer does -
Hi Phil,
I totally agree, as I state in my post, that the SB or TP normally
provide the clock and Slimserver slaves to it, providing audio data
as required. However, with most Internet radio, the server provides
the clock, so the SB or TP must slave to it. AFAIK, the SB and TP do
not actually
I don't know how the Internet radio stuff works - but I'm pretty sure
that the synched SB's are simply feeding off a single TCP stream and
doing their own thing just as they do with a single SB - they aren't
synched at clock level. They aren't actually perfectly in-synch!

No, the client is always the clock source even for internet radio.
In the hypothetical scenario where the client is running too fast and
the (presumably live) internet radio source can't produce more data,
then playback would stop and rebuffer. However, there are very large
buffers on both

Wrong again. It's a VFD, Vacuum Fluorescent Display.
