    The WM8958 Audio (Audio Hub) solutions to ensure high-definition audio



    Wolfson Microelectronics has announced the launch the the WM8958 Audio Center (AudioHub) solution, the program is designed for portable multimedia applications to provide high-definition audio (HDAudio), these applications include smart phones, tablet PCs, e-books and a variety of navigation equipment, etc. and so on.

        Solutions combine industry-leading Wolfson's AudioPlus ™? Products together, such as its digital silicon micro-electromechanical systems (MEMS) microphones, power management chip and noise cancellation, this new definition WM8958 architecture The high-definition quality audio set up a benchmark.

        This multi-channel ultra low power audio hub solution during the playback of the digital-to-analog converter (DAC) provides 100dB signal-to-noise ratio (SNR), while its built-in stereo D / Class AB speaker driver and class W headphone drivers can minimize power consumption during audio playback.

        WM8958 with a digital signal processor (DSP) can run a multi-band compressor (MBC) audio enhancement. This ensures significantly louder, more transparent sound from small speakers, without causing overload or damage. Work with an on-board parametric equalizer and dynamic range controller, MBC is able to provide the ability to expand and optimize speaker output, so as to bring exceptional audio playback various multimedia applications and ringtones.

        Stereo sample rate conversion and multi-channel digital mixing capabilities, combined with powerful analog mixer, allow WM8958 support a diverse set architecture and usage patterns.

        A smart digital microphone interface provides power for up to four digital microphones rectifier, a low-jitter clock and decimation filter, active ground loop noise cancellation can help remove the blasting sounds and suppress the headphone output and DC bias correction ground noise.

        The Wolfson audio center product line manager DuncanMacadie Speaking: WM8958 audio center not only provides excellent signal-to-noise ratio (SNR) and ultra-low power consumption, and significantly improved through its multi-band compressor portable applications, multimedia listening experience. and a series of industry-leading Wolfson's AudioPlus ™? combination products, WM8958 will put high-definition audio brings next-generation multimedia devices.
