iPhone 4 study shows same noise cancellation as Nexus One

iPhone 4 has same Audience anti-noise as Nexus One

A follow-up teardown at iFixit has revealed that the iPhone 4's noise cancellation is the same as in the Nexus One. Previously unidentifiable, a mystery chip on both has been given a close look in a ChipWorks scan and is now known to be an Audience A1026 audio signal processor. Both the Apple and Google phones are well-known for their near-ideal ability to filter out background noise and are now know to have accomplished that by using the same hardware.

Both chips had gone largely undiscussed until now due to their lack of marking. Neither Apple nor Google's partner HTC identified the chip and in both cases gave them generic numbers that couldn't be identified. Such chips are common but are usually very minor chips that don't have a noticeable impact.

Audience is likely getting repeat use, both on any future iPhones and in HTC's newer Android and Windows Phone hardware.
