Automatisierte Lautsprecherentzerrung mit Kautz-Filtern

A Kautz-filter cascade can be used to implement a customized frequency resolution for equalization of loudspeaker responses. This is particularly interesting for automatic eqalization as no (third-)octave filter bank has to be designed and manually adjusted. According to a paper from Paatero and Karjalainen, it is sufficient to design the frequency resolution, and use the filter structure with the impulse responses to solve normal equations. This seminar paper shows the mathematical formulation and practical results using a minimum-phase conversion.
