It's hard not to respect good detective work, so we have to give kudos to the good folks at Chipworks
for putting a long-lived iPhone mystery to rest. The iPhone 4 has been applauded for its dual-mic noise cancellation
, but nobody knew who actually built the voice processor responsible for this "magic and revolutionary"
feature. Jobs and Co. white-labelled a certain chipset inside the iPhone 4 -- it asked the manufacturer to scrub all branding off -- so nobody could properly identify it. Was it made by Apple or a third party? Fast-forward nearly eleven months and it turns out the company responsible is none other than Audience, the same lovely folks behind the Nexus One's
renowned noise reduction
. We're unsure why this was kept under wraps for so long, but we can understand why Apple would want to remain quiet and keep this superb technology all to itself. A little sleuthing can go a long way, however, so follow the links below to learn how this mystery was unraveled.
