IRIS System Adds Ambeo VR Mic Support

Marshall Day Acoustics and Sennheiser collaborate for room acoustics measurement system.

New York, NY (September 9, 2019)—Marshall Day Acoustics’ IRIS room acoustics measurement system will now support Sennheiser’s AMBEO VR Mic.

The IRIS measurement system utilizes an Ambisonics microphone, such as the AMBEO VR Mic, which is placed at a listening position. A loudspeaker at a source position creates a single-sweep sine stimulus to excite the room, allowing the IRIS software to record the room’s impulse response in 3D and immediately process the results.

IRIS visualizes how the room’s surfaces reflect sound to the listening position in three dimensions, and the 3D image plot created by IRIS can be used to relate sound rays to physical features of the room, observe the directional distribution of early and late sound energy, as well as identify surfaces causing problematic reflections.

IRIS also allows users to export 3D impulse responses, which can in turn be used for rendering recorded spaces into virtual and augmented reality environments.

“We are really thrilled to have Marshall Day Acoustics join our ‘AMBEO for VR’ partnership program,” said Véronique Larcher, director, AMBEO Immersive Audio at Sennheiser. “Moreover, it’s great to be entering the field of room measurement with the AMBEO VR Mic, an Ambisonics microphone.”

“IRIS is among the premier room acoustics measurement systems in the world and one of the few that enables full spatial analysis, which is such a critical part of room evaluation,” commented Daniel Protheroe of Marshall Day Acoustics. “We are very happy to now be able to offer our customers direct support for the Sennheiser AMBEO VR Mic through the inclusion of the AMBEO A-format to B-format converter.”
