I saw that too.  a lot of EE times articles are just
regurgitated
PR, which is fine I guess for trade magazines, but usually
not that
balanced.  as you hint at, FLAC latency can be tuned down to
the 2-10
msec range too, and libFLAC has encoding modes that are
nearly as
fast as decoding.  even more is possible with a hardware
implementation, but it's been a while since I wrote any HDL
and don't
have the spare time for it.
