maybe this has already been covered elsewhere, but..

one frustration of using airtime in a live situation with a console
is that you can't reencode post console audio without breaking metadata. This (messy?) hack solves that by grabbing the artist
and title info, parsing it and dumping it to a file for another encoder
to read.

I was getting the info from the /api directory from the
webserver. you could probably get it from a log file somewhere, but
this works.

 first, in airtime, go to system / preferences and enable "allow remote websites to access schedule..."

get
curl, awk, sed and butt.  probably, you already have awk and sed on
your system. for systems with apt, getting curl is probably something
like "sudo apt-get install curl" 
b.u.t.t. (broadcast using this
tool) is an open-source encoder which can pick up the metadata from a
file. you can get it from butt.sourceforge.net

copy the following and make a script. don't forget to make it executable! i called mine ./metadata_grabber.sh

curl -o metadata1 localhost/api/live-info
cat metadata1 |awk -F"," '{print $(NF-40)}' >metadata2
sed 's/"current":{"name":"//' metadata2 >metadata3
sed 's/"//' metadata3 >metadata4
cat metadata4


great! 
so when that script is run, it'll copy the live-info page from your
local machine, parse it, and redirect it to a file called metadata4 and display
that file just so you can test whats going on. assuming everything
looks good, you can schedule this (although i'm sure there are more efficient
ways) by stacking it in cron.  type crontab -e and enter the following
lines to run it every 15 seconds

* * * * * ./metadata_grabber.sh
* * * * * sleep 15 ./metadata_grabber.sh
* * * * * sleep 30 ./metadata_grabber.sh
* * * * * sleep 45 ./metadata_grabber.sh

save and exit.
configure
butt to read the metadata from the file metadata4, and you'll now have the
ability to retain airtime metadata while incorporating all of your
outboard gear.



please post your improvements or questions!
