The 0600 Series
The 0600 Series
Soundskrit’s SKR0600 directional MEMS microphone provides next class audio pickup for today’s consumer electronics, with a focus on flexibility for products of all form factors. It provides a dipole pickup pattern but can be easily configured to provide any number of cardioid beam patterns, without the use of any software. With an incredible SNR of 67.5dB, the SKR0600 is the ideal choice for space-constrained products that need close sound port spacing or devices encountering far-field sound sources. For content creators and gamers that need professional-level and immersive audio, the SKR0600 makes it all possible. Currently, the SKR0600 is the industry’s lowest noise directional microphone.
The 0600 series is available in both Analog and Digital.

Our Unique MEMS Design
High SNR
The 0600 series of microphones offers an outstanding 67.5 dB SNR with natural background noise rejection, a greater than 14 dB improvement compared to alternative omnidirectional microphone arrays.
Far Field Applications
The ultra-low noise floor of the 0600 series of microphones makes them an ideal candidate for products that wish to capture audio sources far from the microphone.
Multiple Directional Modes
The 0600 series of microphones can be easily configured to provide a dipole, hypercardioid, supercardioid, or cardioid polar pattern through the application of an acoustic mesh.
Small Form Factor
The 0600 series of microphones can be used with very small acoustic port spacings to fit into a variety of space-constrained devices.
Frequently Asked Questions
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.
An omnidirectional microphone listens to every direction equally, providing uniform sound sensitivity. Omnidirectional microphones require the use of multiple microphones and software to provide directionality. A directional microphone is built to be directional, with natural noise rejection from off-axis sources. Using both microphones together can be a powerful combination to maximize flexibility. To learn more about combining directional and omnidirectional microphones check out this article on combining microphone polar patterns.
Our microphones are inherently directional. They provide directionality in the hardware alone, without any need for software. However, we have also built expertise in algorithms to further enhance the performance and features of our microphone. To learn more, check out our software page.
With a distance factor of almost 1.75, a dipole microphone can listen ~75% farther than an omnidirectional microphone of similar SNR.
Directional microphones have two sound ports, one in the front and one in the back. It is not always obvious how to design the acoustic ports in a product. There are many ways to bring the acoustic ports of the microphone to different surfaces in a product. Our app note AN300 helps illustrate some of the most common methods we see.
No, all directional microphones have a non-flat frequency response. When we calculate the SNR, we take this into account by looking at the signal-to-noise ratio at each individual frequency, integrated across the audible spectrum. This is equivalent to taking the SNR post-equalization of the microphone.
