While at Audience for nine years, Massie served as the director of DSP chip architecture, focused on developing “the most advanced audio processing algorithms available for speech enhancement.”
This is actually Massie’s second stint at Apple. In 2002, he was responsible for the audio input/output system on Apple desktops and notebooks.
As noted by MacRumors:
Apple and Audience have a history of working together, with Apple licensing Audience’s voice processing technology to use in its iPhone 4 and 4s. The Cupertino company used a standalone voice processing chip from Audience in the iPhone 4 and opted to incorporate this signal processing functionality directly into the A5 chip used in the iPhone 4s. Audience’s earSmart noise cancellation technology was a key component powering Siri in the iPhone 4s.
On his LinkedIn page, Massie said that he was joining Apple to work on “audio stuff.”
