CES- Las Vegas -- Conexant Systems, Inc. unveils its new complete solution – an I2S Audio CODEC and AudioSmart software – that improves audio and voice processing in tablets. Touted as the industry’s first tablet CODEC with an integrated smart amplifier, the CX2072x when combined with the AudioSmart software achieves a 2x improvement in loudness in small, thin tablet speakers and supports a high performance single microphone voice processing configuration, said the company.
The voice and speech processing AudioSmart software provides noise cancellation and full-duplex acoustic echo cancellation to improve listening performance and voice quality in noisy, real-world conditions. The CX2072x CODEC and AudioSmart software solution is compatible with all platforms and processing systems – ARM- and Intel-based SOCs, Windows and Android OS.
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,” explained Conexant.
In addition to the improved performance, the voice processing solution is said to lower manufacturing costs. It works with one or two microphones and is not sensitive to hardware manufacturing variability, which helps lower the bill of materials (BOM) and manufacturing costs, said the company.
