The magical chip that delivers Nexus One's call quality

Those who’ve tested a Nexus One phone have raved about the phone’s ability to isolate a human voice from the racket of the big city. Much of the credit goes to a chip, the Audience A1026 voice processor, hidden inside the phone.

Google mentioned the Audience chip in its blog post on Nexus One launch day, but the post buried the news and focused on Google’s allegedly unique approach to selling phones.

I can’t see myself at a local bar raving to drunk patrons about Google’s innovative retail strategy. But this phone? You gotta try it. Leave the apps alone and try making a voice call with it. You won’t believe it. The Nexus One’s rock-solid voice quality may bring phone sex back to smartphone users.

audienceA1026A spokeswoman for the company said in an email, “Audience’s third generation voice processor is based on the intelligence of the human hearing system and offers a single, mixed-signal system-on-chip solution that integrates with two microphones in a mobile phone to uniquely identify the primary voice in conversation and eliminate surrounding noise. It also automatically adjusts voice volume and equalization during calls to adapt to local noise interference.”

Mountain View-based Audience was founded in 2000 and has received at least $15 million in funding, much of it from Paul Allen’s Vulcan Capital. Other investors include NEA, Tallwood Venture Capital, and Venture Tech Alliance. Founder Lloyd Watts studied audio processor chips under Caltech legend Carver Mead.
