Noise Cancelling in Software?

Posted by ryuzaki0 on from the how-well-would-that-work dept.

doc_verma wonders: "There are directions to build noise-cancelling devices in hardware, but what would it take to create noise cancelling in software? Since computers have a speaker-of-sorts and can possibly have a microphone, why not take the input from the mic, reverse-phase it via software, and output it through the speaker? A noise-cancelling feature would be great to run on servers in a rack. It would also be a great app to run on your laptop when you are on a plane."

    the only stores for thousands of miles in any direction sold only alcohol, Mormon cookbooks, and knives.

    Sounds like a bad day for the Mormons if you're hungry.
