FIRmaker does not generate linear phase filters. As such, the filters are not symmetrical in time about the peak of the filter’s impulse response. There is no requirement for the filters generated by FIRmaker to have pre-ringing. The transient behavior of the system will not be influenced.
Since AFMG FIRmaker is a technology that deeply influences the complete system behavior from the DSP block through limiting, amplification, crossover (or vice-versa) to each transducer, AFMG will implement the technology in close partnership with each loudspeaker manufacturer.
FIRmaker results are available in a few seconds. Simple setups typically require 2 to 10 seconds of computation time, complicated setups require 10 to 30 seconds.
These numbers are based on the performance of readily available laptops. Performance will probably be increased even more once specific implementations allow further customization of the underlying algorithms.
No, FIRmaker can also be used in loudspeakers equipped with on-board DSP. This applies for example to more sophisticated powered line arrays as well as to digitally steerable column loudspeakers.
In general, any possible combination of DSP / amplifyers / transducers within single or multiple cabinets or in a unified housing is possible as long as the hardware and DSP software allows storing of separate FIR filters into every DSP block.
Yes. AFMG FIRmaker only requires high-resolution loudspeaker modeling data as well as FIR processing capabilities. It will work with both, purpose-designed systems as well as existing products.
FIRmaker could even be applied to improve existing installations for better musical performance, increased speech intelligibility or higher signal-to-noise ratio.
No, FIRmaker is using high-resolution loudspeaker modeling data to simulate the performance of the system. Based on that FIRmaker computes optimal FIR filters for each DSP channel. Extensive tests in the field have shown that the accuracy of the simulation predicts system performance better than measurable differences of the real setup.
On-site measurements e.g. with SysTune or EASERA can, of course, be performed additionally to refine the performance and align the array to other parts of the sound system.
All versions of EASE Focus run on almost every modern Microsoft Windows computer. The following parameters can be seen as an appropriate basis:
This is the White Paper for AFMG FIRmaker. It contains detailed information on the FIRmaker technology, comparisons between optimized and non-optimized systems as well.

FIRmaker is able to work with any number of DSP channels. AFMG's general-purpose approach is one DSP channel per cabinet.
In very large arrays it will be possible to combine two or even three cabinets into a single source driven by one FIR DSP channel without too much trade-off.
The number of FIR and amplifier channels used per cabinet is not limited, on the other hand. Dozens of channels could be calculated by FIRmaker per box. Even vertical + horizontal optimization would be possible if implemented by the loudspeaker manufacturer.
