z.b.? laut manual: https://www.trinnov.com/Support_download/user_manuals/Optimizer_English_Manual_V3.8.pdf 1.4Automatic Optimization The Optimizer uses state-of-the-art time-frequency algorithms to analyse calibration measurements and uses specific methods to compensate for direct sound, first reflections, late reflections/reverberation and room modes. All the subtlety of the Optimizer resides in knowing which defects may be corrected without creating additional problems. Improved Phase Response: the Optimizer corrects the frequency response of the speakers, both in amplitude and phase. This means that the Optimizer corrects both the tonal balance to obtain a neutral timbre for every speaker and it also works in the time domain to achieve a high resolution stereophonic image with well-focused phantom sources. Target Curves: the Optimizer automatically defines the filters that will achieve the required frequency response defined by a target curve. This is particularly useful in Film Studios in orderto comply with the X-Curve SMPTE and ISO standards. Phase and Group Delay targets may also be defined, making the Optimizer a unique tool for sound system designers. Fine-tuning options: the Optimizer provides over 12 different parameters, such as maximum boost/attenuation, to customize the behaviour of the room correction algorithms. This opens many possibilities for fine-tuning the sound according to loudspeaker capabilities and listening tests. hmm.. phase response.. ok..
