A Greybox Information
PURPOSE FOR GREYBOX FILES
In Loudspeaker Processor mode, the UX8800 allows loading files with
Often, audio system designers, technicians, or
•Loudspeaker data far greater in quantity, types, precision, and accuracy (especially polar data).
•Use of proprietary analysis tools developed specifically for loudspeaker data.
•Use of proprietary Gunness Focusing algorithms for the processing.
•Extensive listening tests performed by a wider range of people over a much greater time period and under a much greater range of conditions.
•Controlled, laboratory conditions.
•Extensive knowledge in the application of loudspeaker data analysis and signal processing.
B System Processor Mode Processing
In System Processor mode, the UX8800 may appear similar to other digital signal processors. However, the processing algorithms used in the UX8800 differ from the normal, “textbook” algorithms used in digital processors. EAWdeveloped new algorithms specifically tailored for digital audio processor hardware.
FILTER RESPONSE EXAMPLE
The accuracy and precision of the UX8800 filter responses can be compared to those using textbook algorithms. When applied to audio processing hardware, the latter do not provide textbook responses. The two graphs compare the results of EAW’s processing algorithms and standard “textbook” algorithms as used in
1.The upper curve is the upper curve becasuse its filter skirts extend somewhat beyond that of an ideal filter. In this case, the lower
