The solution for demanding applications

The most fundamental component in the audio signal processing chain is the microphone that converts real world audio to an electrical signal and presents this for application processing – or just pure audio recording.

Breaking with traditions

Traditionally, the approach to increase application performance is to increase the number of microphones and add post-processing capacity. The sensiBel true studio-quality MEMS microphone will enable the most demanding applications to break with this tradition.

Application areas

 

Super-directivity microphone arrays

Microphone arrays are used in many applications for far-field voice and sound capture and suppression of unwanted noise. Voice user interfaces, sound detection systems and conferencing solutions typically include a microphone array to focus the capture on the person speaking.

The most critical microphone parameters for array configurations are the microphone SNR and sensitivity matching between the individual microphones elements. High SNR translates to improved beam forming, in other words, even better focus on the sound of interest. sensiBel’s high SNR microphone is a key enabler for the next generation improved microphone array solutions.

White paper - Enabling superior microphone array beamforming using 80 dB SNR MEMS microphones

Multi-microphone solutions have been increasingly replacing single microphones to improve acoustic performance and end user experience. The overall acoustic performance goal is to achieve a high-quality reproduction of the desired signal (voice, music etc) without any noise (undesired environmental sounds or system noise). This white paper describes how the sensiBel SBM100 80 dBA SNR optical MEMS microphone provides significant performance benefits for microphone array beamforming by focusing on three popular algorithms; Delay-and-Sum, Differential and MVDR. Combining the superior microphone array beamforming performance with advanced system processing capabilities allows, among many other applications, clearer voice calls, superior audio recordings, more productive conference calls and immersive 3D AR/VR audio experiences. The SBM100 series brings this level of performance to MEMS microphones and to beamforming arrays for the first time.
