It's probably advisable to not mention this to T-Pain or anyone even closely related to him, but it looks as if auto-tune may have finally found a legitimate use. You know -- aside from crafting one of the most hilarious Bud Light commercials in the history of Bud Light commercials. An EU-funded team has crafted a prototype device that uses a technology similar to auto-tune in order to nix cross-talk on signals that travel down fiber optic cabling. Currently, the clean up process on phase noise ends up decimating the total capacity available to travel, so far less information actually gets through the end than what you started with. Now, this here device is claiming to spit shine the noisy signals and "re-transmit them with fuller capacity." Periklis Petropoulos, a researcher on the project from the University of Southampton's Optoelectronics Research Centre, summed it up as such: "With this demonstration we've shown that it is possible to use the capabilities of the optical fiber to the full without being restricted by the capabilities of the electronics; you could say that in its final functionality, it is like auto-tune." Obligatory video demonstration is after the break.
