He's going to regret having mentioned that. Now he'll get calls from
people who never noticed a problem saying it's destroying their
listening pleasure. I spent 10 years with WOR running their radio
network. Unscientific surveys of affiliates always told me we had the
best level control of the many networks they ran. I don't know what
John can do about it. WOR is a Talk station and, as such, is heavily
processed. That's not the problem. Advertising agencies equalize
their spots to favor the spectrum the ear is most sensitive to. Get
rid of the low end, do a little magic and the spot sounds louder but
the processing doesn't hear it that way. It's been a problem since
the dawn of radio advertising. You'll probably notice that spots cut
at the station don't have that problem. It's not the station's
problem beyond the heavy processing of everything. If you try and
lower the level in the studio the processing brings it back up. I
understand that's one of the main reasons for multi-band processing.

It's a number of things. Due to AFTRA regulations stations can't
stream agency spots without subjecting the ad agency to higher talent
fees. Most stations use a third party service to substitute other
material to cover the spots. It's very tough to do.
When a show is locally produced it's relatively easy to insert cue
tones to activate the substitution. If the station is running an
external network there's no way to cue the substitution. Many
networks run their network spots first in a break without a cutaway
cue. That's to prevent unethical stations from running local spots
where, by contract, the network spots should be. Most networks have
at least a few "floating" breaks. Without the cues the stream runs
the prohibited spots. When I was there WOR never ran programming
(except overnight news) from any external network. Now they produce
much less local stuff and take syndicated shows from networks that
may have different cueing or none at all for spots. I set up the
original WOR stream with the long gone broadcast.com. That was before
the AFTRA problem and everything ran simply as a simulcast. When
AFTRA stepped in we talked with several substitution services. At the
time, none could figure out how to handle breaks without cues. I'm
not sure if they're using a service or just going silent during
breaks. I'll call to find out.
