EASE Data For Thirteen (13) Meyer Sound Loudspeakers Now Available

With the release of EASE 4.3, the software can now import and view Meyer Sound's one-degree measurement data in the GLL format

Meyer Sound has announced the availability of high-resolution measurement data for 13 of its most popular loudspeakers in the GLL (Generic Loudspeaker Library) format, enabling users of EASE design and simulation software to model the interaction of Meyer Sound self-powered loudspeaker systems with the acoustics of rooms.

With the release of EASE 4.3, the software can now import and view*** Meyer Sound’s one-degree measurement data in the GLL format which is considerably higher resolution than the EASE SPK file format used by previous versions of EASE, resulting in more precise predictions.

The following product GLL files are now available for download from Meyer Sound’s website:  MILO (60, 90, 120), MICA, M’elodie, 700-HP, 600-HP, 500-HP, UPQ-1P/2P, UPJ-1P, UPJunior and SB-3F. To register and download any of these files, please visit: 

As additional product data becomes available the page will be updated, and registered users will be informed via email.

Meyer Sound’s patented MAPP Online Pro acoustical prediction program will continue to be the preferred prediction tool and provide the most accurate reference for modeling the interaction of Meyer Sound loudspeakers.

“The utility of acoustical prediction programs depends on several factors, including the accuracy of the measurement data used to model the individual loudspeakers, the consistency of the product from cabinet to cabinet, and finally on the quality of the algorithms used to process that data,” said Meyer Sound CEO John Meyer.

“While EASE is designed to incorporate articulation data and room acoustics information, MAPP is designed to facilitate aligning loudspeaker systems with the highest level of accuracy, and therefore took care to exclude room data. With its ability to incorporate higher-resolution GLL data, EASE has become a much more useful platform for accurate system modeling, enabling its users to evaluate Meyer Sound loudspeaker performance simulations with a good degree of confidence.”

“We are pleased to be working with the EASE team to provide users with more accurate and useful predictions,” added Meyer, “and give customers the tools they need to effectively evaluate and specify Meyer Sound loudspeaker systems.”

“For years, John Meyer and I have pushed to advance technology that would empower system designers with prediction tools offering high accuracy, interoperability, and advanced functionality,” said Dr. Wolfgang Ahnert, the scientist behind the EASE program.


“We are both pleased to witness the industry’s widespread adoption of acoustical simulations, and look forward to seeing system designers and the audio education community benefit from EASE’s compatibility with Meyer Sound data.”
