Conexant Debuts I2S Audio CODEC with Integrated AudioSmart Amplifier for Tablets

Coupled with Conexant AudioSmart Software Offers Unparalleled Audio/Voice Performance; Supports Single Microphone Solution

LAS VEGAS — (BUSINESS WIRE) — January 6, 2015 — This week at the 2015 International CES, Conexant Systems, Inc., an audio and imaging innovation leader, will debut its new complete solution – an I2S Audio CODEC and AudioSmart™ software – that improves audio and voice processing in tablets. The industry’s first tablet CODEC with an integrated smart amplifier, the CX2072x coupled with Conexant’s AudioSmart software achieves a 2x improvement in loudness in small, thin tablet speakers and supports a high performance single microphone voice processing configuration.

Conexant’s voice and speech processing AudioSmart software provides noise cancellation and full-duplex acoustic echo cancellation for excellent listening performance and voice quality in noisy, real-world conditions. From making a Skype call to leaving a voice message on Facebook Messenger, Conexant’s AudioSmart software enables a better user experience and makes challenges with background noise and competing sounds a thing of the past.

Targeted to Windows- and Android-based tablets, Conexant’s AudioSmart software is based on its proprietary SSP noise suppression algorithm. SSP is a blind source separation technology that uses spatial representation of target speech and noise sources to reduce interference. Unlike traditional technologies, such as beamforming, speech and noise can arrive at any angle relative to the microphones; SSP even removes noise when it comes from the same direction as desired speech and when the speaker is up to five meters away from the target device.

Conexant’s CX2072x CODEC and AudioSmart software provide the following key benefits:

  • Compatible with all platforms and processing systems – ARM- and Intel-based SOCs, Windows and Android OS.
  • Louder and excellent listening quality – Tablet speakers have loudness issues due to their slim designs. The CX2072x provides at least 2x the loudness while maintaining the thin form factor, protecting the speaker and delivering excellent perceptual listening quality.
  • Better communication performance – World’s best noise reduction provides a crystal clear, rich audio experience.
  • Lower manufacturing costs – The only voice processing solution available that offers high quality performance in a single-microphone solution. Conexant’s voice processing solution works with one or two microphones and is not sensitive to hardware manufacturing variability, thus lowering BOM and manufacturing costs.

“Traditionally, consumers have come to expect inferior audio on their tablets due to the small form factor – but that doesn’t have to be the case,” noted Saleel Awsare, Conexant vice president and general manager. “Consumers want their conversations to sound clearer and their music and movies to sound louder. Our technology delivers an improved audio and voice experience – anytime, anywhere, and independent of position, distance and orientation. We have successfully deployed our technology in PCs and Smart TVs and are now extending it to tablets, as well as phablets and wearables.”

Part of Conexant’s AudioSmart family, the CX2072x and AudioSmart voice/speech software solution are now sampling. Please visit for more details.
