Hey! I created this website and have been maintaining it along with my friend Alec for the last decade. Fun seeing it pop up here on HN. Thanks for sharing!
Web designers really, really need to stop putting light grey text on a white background. Good article though.
Gosh now I’m imagining if people did this with books. At least chapter books are mostly the same.

Article doesn't mention one of the more interesting (to me) aspects which was how feedback was avoided. The solution is elegant: each vocal microphone is doubled, meaning there are two at each position. The phase is inverted on one of them, the singer sings into only one, and both are sent to the speakers via their channel's amp. The effect of that setup is that only the difference between the two microphones is ampl…
While it's true that they did that and why, I'd ultimately chalk it up as more of a flaw than a feature. Vocals never sounded great on wall of sound shows because they could never sing perfectly into one mic. This can be confirmed by listentng to soundboard tapes of the shows, and comparing them with ones a year or two either side - the full on Wall was only used for about a year. While the WoS laid much of the groun…
It was Donna.

Another cool thing you can do with line arrays is beam steering, you can direct the sound to a certain extent. There are tradeoffs, but I always thought that was pretty damn magical.
Isn’t the audio setup in that LED ball in Vegas a bunch of beam steering?

Here's a fun one. I'm involved in maintaining the audio system for an auditorium used by a non-profit. After a flood and remodel, including replacing some audio components (like microphones), it was observed that the microphone on the main podium always had a 60 Hz hum. The hum depended on where the microphone was facing. Sometimes it was there, sometimes it was not. Being a non-profit facility, there are no fancy DS…
It's been quite a few years since I last worked in live show production, but on any show at a venue where we couldn't be sure of access to clean power, humbuckers (not the guitar pickups, a nickname for what I believe was just a dumb 60hz notch filter or ground loop isolator inlined on house power taps) were a standard pack out in the road kit. I would have expected that this decades-old and well established componen…
A simple notch filter won't fix 60 Hz hum. Or, at least, when I've tried to eliminate annoying 60 Hz hum in my own amateur recordings, it's never been very effective. The problem is that the 60 Hz hum isn't a sine wave. It's more like a square, so you've got a bunch of harmonics up the frequency spectrum to worry about too. You can try to also notch out 120, 180, 240, etc. but it starts to get weird sounding fast.

Since balanced cables predate the GD, this strikes me as an acoustic implementation of an EE concept. Neat!
But as for the acoustic implementation, even that has a long history. The Dead borrowed the idea from fighter pilot headsets, the only difference being that pilots were contending with a noisy cockpit rather than feedback. Same general idea that the unwanted sound hits both mics somewhat equally while the voice hits both mics somewhat unequally.

Why those bands, and not others? What do they have in common?
