The Ultimate Equalizer is an advance software tool which allows rapid and accurate development of minimum phase or linear phase crossover filters for active loudspeakers and plays these crossovers using a suitable multi-channel sound card on a PC. When used to design linear phase crossovers, the minimum phase associated with the woofer system high pass cut off is also linearized resulting in an active loudspeaker that has near perfect response with no time domain distortion, relative to the design point, over its entire frequency range.
Once the filter transfer functions are generated they are placed in a suitable format for emulation using long FIR digital filters. The design process consists of three fundamental phases:
1) Accurate measurement of the individual driver SPL response;
2) Defining the acoustic targets for each passband of the multi-way loudspeaker;
3) Construction the filter transfer functions which, when combined with the drivers’ SPL response, produces the targeted acoustic output.
The Ultimate Equalizer includes a measurement system to obtain the required SPL data or SPL data may be imported from other measurement systems; includes a baffle diffraction simulator to model and correct the driver response for the baffle step as required; provides a library of high and low pass functions for defining the acoustic targets; and reduces the construction of the filter transfer functions to a simple mouse click for both minimum phase and linear phase systems.
