Apple is apparently continuing to expand its digital audio expertise by recently adding digital signal processing (DSP) expert, Dana Massie, to its team as an (system-on-chip) SoC Audio Architect. For those of you who may not know, Massie has over 30 years of experience working with DSP hardware and software architecture with high-profile companies including Audience and Waves along with brief work with both Apple and NeXT. Massie was previously the Director of DSP chip architecture which focused on developing “the most advanced audio processing algorithms available for speech enhancement.

Furthermore, both Apple and Audience have a long-relationship of working together as Apple licenses Audience’s voice processing technology to use in its iPhone 4 and iPhone 4S. The Cupertino California company used a standalone voice processing chip from Audience in the iPhone 4 and ended up incorporating this signal processing functionality directly into the A5 chip that was used in the iPhone 4S. That wasn’t the only piece of technology used either as Apple also used Audience’s earSmart noise cancellation technology to help power Siri in the iPhone 4S.

Massie is now set to work at Apple as the SoC Audio Architect after a six-week sabbatical upon leaving Audience. It’s unclear what his exact duties at Apple will end up being as he claims he will only be working on “audio stuff” in his LinkedIn profile. Given what he’s worked on in the past, it’s likely that he may end up working on improving voice recognition technology or improving audio quality in future Apple products. We’ll have to wait and see.
