Audio Hub Solution Enables HD Audio

Thu, 10/28/2010 - 7:02am
Audio Hub SolutionWolfson Microelectronics plc has introduced WM8958 audio hub solution, designed to enable high definition (HD) audio in portable multimedia applications, such as smartphones, tablet computers, eBooks and navigation devices. When combined with the company’s AudioPlus products, such as its digital silicon micro-electro-mechanical system (MEMS) microphones, its power management ICs and noise cancellation solutions, the WM8958 helps set the benchmark for HD quality audio, according to the company. This multi-channel ultra-low power audio hub solution provides 100 dB signal-to-noise ratio (SNR) during digital-to-analog (DAC) playback, while its integrated stereo Class D/AB speaker driver, and Class W headphone driver minimize power consumption during audio playback. The hub features an audio enhancement DSP which runs a multiband compressor (MBC). This enables significantly louder and clearer sound from small speakers, without causing overload or damage. Used in conjunction with an on-board parametric equalizer and dynamic range controller, the MBC provides the ability to boost and optimize speaker outputs to deliver superior audio playback for multimedia applications and ringtones. Its stereo sample rate conversion and multi-channel digital mixing, combined with powerful analog mixing, allows the WM8958 to support a huge range of different architectures and use cases.
