Phase drehen - wie wirkt das?

Hallo,

zu diesem Thema habe ich einiges an Fachliteratur, allerdings alles auf Englisch. Bei Interesse kann ich die pdf's schicken, PN mit email-Adresse genügt.

“While polarity inversion is not easily heard with normal complex musical program material, as our large- scale listening tests showed, it is audible in many select and simplified musical settings. Thus it would seem sensible to keep track of polarity and to play the signal back with the correct polarity to ensure the most accurate reproduction of the original acoustic waveform.”

“The important point is that there is a well-established mechanism in the inner ear for detecting waveform asymmetries and hence polarity reversal of asymmetric signals. What is perhaps surprising is how subtle this effect generally appears to be on music and speech. As the above-mentioned experiment [13] indicates however, it is an audible factor, and should be taken into account when performing comparisons of audio components [15], [19], [20] -- acoustic polarity should be maintained.”
