Townsend Labs earns patent for innovative microphone technology

Campbell, California, October 8, 2020: As reported by Production Expert, Townsend Labs has successfully been granted another innovative US patent that pushes the envelope for professional microphone technology. Parts of this new patent will find their implementation in a forthcoming, free update of the Sphere plug-in, the software counterpart to the award-winning Sphere L22 microphone.

About the Patent

The US patent US10701481B2 describes a device, system, and method for modeling microphones and a microphone sound-isolation baffle that can be used with microphone modeling. The microphone modeling device can account for the effects of a microphone modeled with a microphone sound-isolation baffle and reduce unwanted audio coloration.

Authored by Chris Townsend, CEO and CTO at Townsend Labs, the patent lays out several concepts to help musicians and engineers achieve great recording in challenging spaces. 

Chris Townsend comments:

At a time when more people are working from home studios than ever before, we set out to conceptualize and design technology that helps overcome some of those new challenges”.

From the beginning, Sphere’s technology has been more than just the accurate modeling of sought-after microphones. Townsend Labs’s proprietary Off-Axis-CorrectionTM (OAC) already provides tools to reduce the amount of room pick-up and coloration. As explained by Townsend Labs in a recent blog post, OAC can help optimize the sound of a vocal booth. The fact that Townsend Labs has earned another patent for innovative microphone technology is a testament to our continuing quest for excellence.

What to Expect

While the details still remain under wraps, Townsend Labs can disclose that parts of the patent will be implemented in the next software update for the Sphere L22 microphone. This new release of the Sphere plug-in, which will be free of charge, will add tremendous value to existing and future owners of the Sphere L22. The software update is coming in the fourth quarter of 2020.

About the Sphere L22

Since its debut in 2016, the Townsend Labs Sphere L22 has established itself as the best microphone modeling solution. Its pioneering multi-dimensional modeling technology and unique dual-channel design take microphone modeling far beyond merely mimicking the static on-axis response of the original microphones. 

The Sphere L22 system consists of a dedicated, dual-channel microphone and its software counterpart, the Sphere plug-in. The exacting models incorporate transient response, harmonics, proximity effect, and multi-dimensional polar response. Thanks to Townsend Labs' exhaustive and curated study of classic microphones, the Sphere system currently brings the soul of 30 of the world's most revered microphones to life. The striking accuracy and sonic results have convinced owners from home recordists to seasoned industry veterans, such as Joe Chiccarelli, Billy Bush, and Allen Sides. 

Leading pro-audio industry accolades such as Sound on Sound Editors' Choice award, the win of a 2020 TEC Award for Sphere 1.3, and the recent TEC Award nomination for Sphere 1.4 underline the innovative approach of the Sphere L22.
