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.

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).

- 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.

- 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.
