Thanks to all of those who gave me running feedback on our first
dabble with webcasting. So far as I was able to track, we had
successful long-term feeds to Amsterdam, Dallas, Reston (Virginia),
St. Louis, Atlanta, Mt. Laurel (Vermont), San Ramon (California),
Banff, Toronto (x3), Montreal (x4), and Calgary. We did notice that
all of those linked used either QuickTime (most) or NSPlayer. iTunes
was 100% UN-successful in linking to our feed when attempted from
outside our campus (on-campus it was OK - go figure). We logged 171
attempted links for yesterdays final day of the Symposium, many of
them were repeat attempts. It was a shame to see people trying to
link using iTunes, only to be dropped off, I'm assuming after failing
to establish as 'good' connection. I wouldn't mind some info on this
problem if anyone has any ideas.

Certainly the EuCuE series from Concordia will be broadcast now that
we understand how easy it is to feed through software like NiceCast.
We will still be fiddling with getting a good mix of the
multi-channel works as well as sending a clean signal. We also found
audio content below 100 Hz was problematic for the compression
algorithms. Ned Bouhalassa's work was especially compromised by the
'full' low end content. The Air-20's, supplemented by our Meyer 600
subs provided quite an experience of his work for the audience in the
Hall, but the pickup distorted I'm afraid in the broadcast.

For those interested, our setup for broadcast was as follows:
        2 Neumann KM 138 Omni's in a spaced pair config, central
audience position
        PreSonus M80 Mic pre-amps
        ProTools 882 input for record/documentation
        Mackie D8B mixer - fed from Pro Tools
        Mains out to Mac Powerbook G4
           BTW - nearly a dozen G4 PowerBooks in attendance at the conference
        Audacity for internal recording
        Ethernet T1 from Concordia on port 8100
                opened port 8100 firewall in Mac Sharing prefs

This might seem like a long way around to get a feed out to the net.
It certainly would have been easier to sit in the audience with
binaural mics connected directly to my laptop (on my lap) to Ethernet
(100' extension) and off we go. But, we normally record all our
concerts using Pro Tools through good mic pre-amps and the modest
converters of the Pro Tools 882's. In that situation we found that
NiceCast wasn't able to access the audio from Pro Tools since PT only
seems to handle the 'audio' feed at the 882's until storing to disk.

I also have realized that we were guilty of being time-centric for
lack of a different word. We (I) kept announcing about our broadcast
started at 8:00...... forgetting to mention that it was Eastern
Standard Time in North America. My apologies to those abroad for that
faux pas.

Always learning,
