iFixit sent out an email blast this afternoon that points to an analysis of the iPhone 4â€²s voice processor that powers the noise cancellation feature of the device.
The noise cancellation technology in the iPhone 4 improves call quality by masking various background noises during phone calls so that both caller and receiver have an optimal experience.
The silicon behind the noise cancellation is an Audience-branded silicon, found by the Chipworks team by X-Raying the chip.
According to iFixit, the find ends speculation as to whether Apple invented their own voice processor or licensed third-party technology.
The package has an embedded digital signal processor with accompanying analog front ends. The iPhoneâ€™s audio cancellation capabilities are very impressive, outperforming just every non-Audience powered cell phone weâ€™ve triedâ€¦ This is a huge win for Audience.
The attention-grabber in the iFixit email blast was that Audience is â€œthe same company that powered the Nexus Oneâ€™s innovative audio cancellationâ€. Looks like Apple and Google think alike. 🙂
