Akustica HD digital mics to go on show

Keywords:CMOS MEMS microphones? HD VoIP? single-chip digital mics?

Akustica Inc. will bare the latest in its single-chip digital microphone family at the Computex trade show in Taiwan next month. The new family of CMOS microphones uses an MEMS diaphragm that conforms to the Telecommunications Industries Association's TIA-920 specification for wideband digital transmission telephony.

"Our new high-definition CMOS MEMS microphones provide as dramatic an improvement in audio quality as HDTVs provide for video," said Davin Yuknis, Akustica VP of marketing and product management. "Our goal is to provide digital silicon microphones that raise the bar of telephony so that its quality rivals face-to-face conversations."

An industry collaborator, Skype Ltd has endorsed Akustica's new family of TIA-920 compatible HD silicon microphones as a logical companion to an upcoming wave of superwideband codecs designed to provide 48Kbps HD-quality VoIP. Texas Instruments Inc. announced such an HD telephony codec last month.

"Akustica recognizes that HD voice quality does not depend solely on the availability of wideband codecs and networks. It is just as important to use a microphone that maintains the original voice input quality as closely as possible," said Jonathan Christensen, head of audio and video development at Skype. "The market is finally starting to realize the dramatic improvement in intelligibility and nuance that HD voice quality brings to an Internet call."
