The Optimizer starts with the acoustic phenomenon that are mostly deterministic, and gradually moves to the ones that are mostly statistic. This automated room correction combines both IIR filters and FIR filters. The IIR filters allow for very accurate equalization in the low range, while the FIR filters work full range.

A subtle approach to acoustic phenomenon

The Optimizer uses a clever combination of modern techniques to generate complex sets of digital filters and achieve the best loudspeaker/room compensation. Its intelligent acoustic analysis engine automatically computes FIR and IIR filters to dramatically improve the consistency of direct sound against late reverberation. Full-phase, time domain techniques are applied compensating for the loudspeaker’s group delay and for very early reflections (deconvolution), while later reflections are left untouched.

Correction of Early Reflections (Direct Field)

The Optimizer analyses the measurements in the time-frequency domain to identify Early Reflections. Depending on their amplitude, frequency, direction and arrival time, the Optimizer will compensate for them to a certain extent, or not try to compensate for them. After this process, each loudspeaker’s response is “clean” from the early reflections that it is possible to correct with digital technology. The other reflections are not touched.

Correction of the Room Energy

In this second stage the Optimizer analyzes the measurements in the frequency domain only (the response of the system in steady state).

  1. Compensation of Resonance Modes (in the low range):
    the Optimizer identifies resonance modes in the range where they can be clearly differentiated, roughly up to 300Hz. It applies individual filters to compensate each resonance mode.
  2. Smoothing of the reverberation (in the mid and high range):
    The Optimizer analyzes the room’s frequency response, related to the coloration of the room’s reverberation. Another filter is applied to smoothly compensate for this coloration.

All the subtlety of the Optimizer resides in its knowledge of the defects that shouldn’t be tried to correct for without creating even more problems.
