Well I'm past the 5-0 mark and I can sure as hell hear it. It's driving me nuts too, and I can't figure out why they haven't been able to squelch it yet. Maybe it's some kind of post glitch in the transmission truck that they aren't hearing on site? It almost sounds like a kind of digital feedback...
I hear it too. Over the air HD on the Global Canada feed.
Maybe a poorly set automatic feedback suppressor?
It sounds to me like when you have a telephone hybrid with a mix minus problem. Causing ringing from the voice coming back to you over a telephone line or cell phone. I know that isn't it, but it sounds exactly the same.
There are sooooooooo many codecs and electronics involved with all the analog to digital to analog it is a wonder that anything sounds good on TV anymore. I only watched a small part of the proceedings but I didn't think the overall sound was as good as it has been in years past. Maybe a different sound company or engineer??? or they were having problems? Maybe it was the satellite up load or some converter somewhere along the line that was having a bad day. Too many places for the signal to get messed up to even think about why or how it happened.
Definitely sounded like a sample rate problem, coming from that podium mic. My wife even heard it. At first we were looking through the baby's toy box trying to find the one that was beeping. Then we thought it was a cell phone going off in the audience...
Very distracting and I couldn't believe it wasn't fixed almost immediately. Something must have been very broken or someone was very deaf.
It's one of the sounds Codecs make when they are not locked completely. Since I doubt they were using codecs for the sound but satellites instead, that would be my guess. I will try and ask our satellite dude if he heard it and recognized the sound. It was clearly a digital lock kind of error, so it is highly doubtful that it was in the room. The strange thing is that I never heard it on anything but the talk mic. I was pretty involved in a project and only slightly paying attention from the other room though.
