21ic News Wolfson Microelectronics Co., Ltd. announced that it will launch its next-generation audio hub product (Audio Hub) with voice processor DSP, which can help smartphone manufacturers to provide clearer and more natural sound even in noisy environments. Voice call.

With integrated transmission path (Tx) noise reduction, echo cancellation and receive path (Rx) noise reduction, the WM5102 ensures clear, discernible, natural conversations and suppresses up to 90% of background noise transmitted over voice calls Whether the caller is passing by a busy train station, or is still at the bar socializing or resting at home.
Designed for smartphones, tablets and other portable audio devices, the high-performance WM5102 features SLIMbus and I2S interfaces, allowing OEMs to expand their audio brand to all platforms using only one audio hub solution. This provides a truly system-independent platform.
The WM5102's other advantages are: it provides a signal-to-noise ratio (SNR) of 102dB, and with 50MIPS of processing power using Wolfson's advanced audio DSP, it provides an excellent high-resolution audio experience and consumes power. drop to lowest. The WM5102 shrinks by up to 20% compared to competitors, while reducing the number of components by up to 17, significantly reducing printed circuit board (PCB) footprint and lowering bill of materials costs for manufacturers.
Its fully digital mixing architecture means the WM5102 is a highly flexible, future-proof and scalable solution that allows for concurrent usage scenarios, ease of integration and fast time-to-market. Its digital core provides a powerful combination of fixed-function signal processing blocks and programmable DSPs, including filters, fully parametric equalizers, dynamic range control (DRC), and sample rate converters.
"By increasing the performance of our DSP on the audio hub to a level not yet available in the market today, while maintaining its ultra-low power performance, we are able to seamlessly integrate the transmission path noise reduction with other audio processing functions." Duncan Macadie, product line manager of Wolfson Microelectronics Audio Center, commented. “Customers are always looking for such high levels of integration to significantly reduce their BOM costs. By adding a SLIMbus interface, we ensure that our customers can use this audio platform on all of their products, regardless of the choice of application processor. â€
