Soundskrit Announces SKR0600 Next-Generation Directional MEMS Microphone With Improved SNR

After the success of the SKR0400, now implemented in a breadth of consumer products, Soundskrit announced its next-generation product: the SKR0600 MEMS microphone. With an improved 67.5dBA SNR, the new directional microphones provide pro-audio quality in smaller footprint. In its standard configuration, the SKR0600 microphone exhibits a dipole polar pattern from 20Hz to 20kHz, and can be converted into any cardioid-based polar pattern with the simple addition of an acoustic mesh.

The Audio Product Education Institute (APEI), an Audio Engineering Society initiative, is promoting a webinar exploring application and optimization of microphone beamforming techniques, and the latest optimizations for voice recognition platforms. The knowledge-sharing online session features presentations from DSP Concepts, Soundskrit, and Fluent.ai, with presentation by Dave Lindberg from DB Enterprises in Hong Kong.

Today, most audio products, from Bluetooth speakers to appliances with voice command, now contain at least one microphone. If the product was designed a couple of years ago, it had an electret condenser microphone (ECM), but today it will most likely use a MicroElectrical-Mechanical System (MEMS) microphone. Spec’ing MEMS microphones has some differences and this article touches upon these points.

When performing electroacoustical response measurements, an important practical consideration is the reduction of uncorrelated background noise. Synchronous averaging (i.e., “complex averaging,” “time domain averaging,” or “vector averaging”) is a technique originally developed to analyze the vibration signature or rotating machines and gearboxes. It can be used to improve the S/N ratio measurement. This article was published originally in Voice Coil November 2012.
