iFixit points at a Chipworks analysis of the iPhone 4’s voice processor that powers the noise cancellation feature which improves call quality by suppressing background noise while boosting the caller’s voice. It’s an Audience-branded silicon, as denoted by the Audience marking innocuously placed inside the chip itself. The Chipworks team has figured this out by X-Raying the chip, as always.
The finding put to rest speculation whether Apple had invented their voice processor or licensed third-party tech. Teardown wizards over at iFixit also noted that a small 3mm x 3mm chip sits right next to the A4 processor.
iFixit’s Kyle Wiend told me in an email that Audience is “the same company that powered the Nexus One’s innovative audio cancellation”. Go past the break for another amazing look at the chip’s innards plus a YouTube clip demoing its noise cancellation capabilities.
