I had a look through the config file and found where the regions are
defined inside each wav file, so if I can find a way to translate
broadcast wav into other formats, then it should be possible to pull out
the recorded tracks using an external program. I.e. save the session, then
run a script that looks for new regions, copies them out of the broadcast
wavs in the .../sounds dir, then uploads them to another machine for
editing / conversion to another format. (The point is to be able to record
live broadcast programmes and then put the recorded file on an icecast
server for on-demand streaming, while the live stream is still running,
and it would be good to have this set up to run fairly automatically if
possible - e.g. just start a script, give the name of the programme, and
it will be added to the web archive automatically.).

The question is whether there's any way to convert broadcast wavs into
other formats using command line tools. sox won't work with broadcast wavs
afaict, so if anyone knows of a command line tool that will convert these,
that would be a help.
