EASE SpeakerLab

Loudspeaker Data Analysis and GLL Creation

EASE SpeakerLab is the software tool used to create, edit, and view loudspeaker models (GLL files) for use with the EASE family of simulation products: EASE, EASE Focus 3, EASE Address, EASE Evac, and FIRmaker.

The Pro version of EASE SpeakerLab adds various advanced simulation and viewing functions as well as capabilities to export to other loudspeaker modeling data formats.

EASE SpeakerLab Basic is bundled as a complementary software with every purchase of EASE Standard or EASE JR.

Loudspeaker manufacturers will benefit from the use of EASE SpeakerLab by being able to create and publish GLL files for their loudspeakers.  Manufacturers, as well as loudspeaker design engineers and application engineers, may find EASE SpeakerLab to be a very useful and powerful design tool.


Once the directivity data and the on-axis response have been measured for a loudspeaker they can be imported into EASE SpeakerLab to create a model for that loudspeaker.
While the GLL data format supports a single set of measurements for a complete loudspeaker cabinet, AFMG recommends so-called multi-source measurements. For a true multi-source measurement set, the complex polar data of each individual driver or pass band of the loudspeaker will be measured separately. This does not only provide the highest quality during simulation but also allows extensive interaction for the R&D engineer.

The multi-source GLL can add crossover filters, equalization, and delay separately to provide an accurate calculation of the total response for the loudspeaker system.
Many different potential filter options can be evaluated very quickly to optimize the design of a loudspeaker system. Measurements of passive, active, or DSP-based crossover filters can also be imported into EASE SpeakerLab and used to calculate the total response for a loudspeaker system.
