Triple tone in phase audibility

Another update in Phase Audibility software : I added a triple tone, that consists of three sine waves at equal frequency distance, F2-F1=F3-F2.

Now we can easily do the Zwicker phase test, just center the filter frequency to same frequency as generator in triple tone position and listen to phase distortion. At 2kHz, I can hear and ABX differences between various filter types.
