The 0600 Series
High SNR MEMS Directional Microphone
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.
SKR0600 - Analog

Dipole Polar Pattern
The dipole polar pattern is the standard polar pattern for all Soundskrit microphones, in their raw form. This polar pattern features directional sensitivity along the Y-axis, while ignoring the X-axis.
Hypercardioid Polar Pattern
The hypercardioid provides the highest directivity index of all the beam patterns and so is best for eliminating background noise that is diffuse, or equally strong from all directions.
Supercardioid Polar Pattern
The supercardioid provides the highest unidirectional index of all the beam patterns and so is best for eliminating background noise that is uniformly distributed from directions behind the microphone.
Cardioid Polar Pattern
The cardioid provides the strongest null directly behind the microphone. It is ideal for eliminating noise from a direct interfering noise source, such as a loudspeaker, as opposed to diffuse noise.
High Performance Dipole
This configuration provides the maximum performance of the SKR0600. With ports spaced 12mm apart, this integration method has an SNR of 67.5 dB. Also accounts for meshes for ingress protection up to IP57.
High Performance Hypercardioid
This configuration uses a simple acoustic mesh to adjust the polar pattern. With ports spaced 12mm apart, this integration method has an SNR of 65 dB.
Compact Dipole
For products with space constraints, we can reduce the port spacing to 8mm with an SNR of 65 dB.
Supercardioid Boom Microphone
This design concept details how to build a boom microphone with an extremely high SNR of 70 dB. The Supercardioid Boom Microphone Design Concept includes schematics for a simple circuit to equalize the microphone to a flat response and ensure compatibility with interfaces designed for ECMs.
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
What is the difference between an omnidirectional and a directional microphone?
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.
Do Soundskrit microphones require software?
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.
Which polar pattern is right for my application?
Each application has different needs. A dipole brings the most rejection on the sides, while cardioids favor noise rejection in the back. Check out these demo videos to learn more!
