They used asbestos-based fake snow. At the time, asbestos fibers were a popular material for fake snow. Asbestos was used as fake snow until the beginning of World War II, when it was needed on ships.
How did they film the poppy field scene in Wizard of Oz?
We have spent the last 20 years trying to use non-directional microphones to get directionality. Why not build the directionality into the hardware from the beginning?
Soundskrit has rebuilt the MEMS microphone from the ground up with directionality in mind, bringing unparalleled performance to the world of audio.
1. A Completely New Mechanical Design
We changed how the MEMS element looks so it would move closely in sync with the surrounding air. Since a sound wave is simply a displacement of air, our MEMS elements closely sense any incoming sound.
2. A New Method Of Transduction
Traditional methods of capacitive sensing typically impede the motion of the MEMS element. We use a new capacitive readout architecture that leaves the MEMS element unobstructed, free to move with the surrounding air.
3. A Package Built for Directionality
We optimized every detail of our microphone package in order to preserve directionality across all frequencies in the audio spectrum. Our microphones are incredibly small—the smallest directional microphones on the market!
Why are Soundskrit microphones different?
Here at Soundskrit, we developed our microphones from the ground up for directionality. To make directional microphones in such a small package, we needed to design a fundamentally new transducer design unlike anything in omnidirectional microphones. With these advances, our high-performance MEMS directional microphones can seem like technology from the future.
This animated video explains how traditional MEMS microphones work and breaks down our technology to explain how our microphones differ at a physical level.
The Highest SNR in a MEMS Directional Microphone
In order to get direction with traditional omnidirectional microphones, two microphones must be placed in an array and subtracted to approximate direction. When doing so, the effective SNR of the of the microphone array drops significantly. Two 70dB omnidirectional microphones placed 10mm apart loose 17dB of SNR!
Soundskrit maintains high SNR while providing directionality in just a single microphone. With over 10dB more SNR than than market-leading microphone arrays, the SKR0400 unlocks incredible performance for our customer’s devices.
Unbelievably Consistent Directionality
From 20Hz to 20kHz, our first-of-a-kind microphones maintain incredibly high directionality from the lowest ends of the audio spectrum all the way up to the highest audible frequencies.
Unlike traditional arrays of omnidirectional microphones which often suffer from a changing directionality pattern across the audio range, Soundskrit's microphones ensure that all the sound you want to hear is isolated with high fidelity.
Our dipole microphones can be used to replace large arrays of multiple microphones, and multiple dipoles can even be paired together to further increase performance and bring a suite of new audio-based features.
The Industry's Smallest Directional Microphone
While directional microphones have been used in the pro audio industry for decades, they have always been constrained to having large form factors. Bringing directional microphones down to the MEMS scale for consumer electronics has always come at the cost of greatly reduced performance, such as SNR.
For the first time ever, Soundskrit has developed a directional microphone that is no bigger than traditional omnidirectional microphones found in your everyday devices with uncompromising performance.
We have co-designed the hardware and software to provide the greatest level of performance. We’ve combined a deep level of understanding of the acoustics around directional microphones with some of the latest advancements in neural networks to develop in-house AI to unlock the full potential of our new microphones. Whether its eliminating background noise and reverb, tracking multiple speakers around a room, or detecting the distance of a sound from the microphone, our AI brings a pallet of new features to end customers.
Check out the performance of our technology for yourself. Whether using the raw output from a single microphone alone or recombining multiple microphones with our proprietary AI, Soundskrit brings an impressive level of performance. We have a solution to meet any need.
