@JaRaBaaaa Unlike the total phase, which is the sum of the minimum-phase and excess-phase components, excess phase isolates the non-minimum-phase behavior associated primarily with delay and other time-domain mechanisms. This separation is precisely the purpose of analyzing excess phase.
@JaRaBaaaa In fact, when we analyze excess phase and excess group delay, we have already removed the minimum-phase contribution associated with the magnitude response.
@JaRaBaaaa If you would like to gain a deeper understanding of the audibility of phase distortion, I recommend reading the following paper:
J. Liski, A. Mäkivirta, and V. Välimäki, “Audibility of Group-Delay Equalization,” IEEE/ACM Transactions on Audio, Speech, and Language Processing,
@JaRaBaaaa 詳しくは、Sean Olive博士が第157回AES会議で発表した「A comparison of in-ear headphone target curves for the Brüel & Kjær Head & Torso Simulator Type 5128」を参考にしてください。Harman Beta 2024 targetの考え方と同様に、lsとhsを追加したDFをTargetとして設定することをおすすめします。
