Hi
The problem with not including time (which an RTA does not) is that one will get a null (with polarity flipped) every 360 degrees of phase rotation. In other words, the measurement will have a null if you are in the correct time but also every wavelength (360 degrees of phase error) as the sources are 1,2,3 etc wavelengths either ahead or behind in time as well.
Since some music is very “time variant” and not a continuous signal, one can have what appears to be a correct alignment with an RTA but in reality be off by one or more wavelengths with one source being far ahead or behind in time.
Best,
Tom
