Janet Jackson had the power to crash laptop computers – The Old New Thing

Janet Jackson had the power to crash laptop computers – The Old New Thing:

The manufacturer worked around the problem by adding a custom filter in the audio pipeline that detected and removed the offending frequencies during audio playback.

And I’m sure they put a digital version of a “Do not remove” sticker on that audio filter. (Though I’m worried that in the many years since the workaround was added, nobody remembers why it’s there. Hopefully, their laptops are not still carrying this audio filter to protect against damage to a model of hard drive they are no longer using.)

And of course, no story about natural resonant frequencies can pass without a reference to the collapse of the Tacoma Narrows Bridge in 1940.

[It’s not the only thing that Janet can crash.]
