This demonstration estimates the level of a tone.
The level of a modulating tone is adjusted until beats are just
heard between the harmonic tone and the modulating tone.
During the first interval a tone of frequency F1, level L1, and phase P1 is played.
During the second interval a tone of frequency F2, level L2, and phase P2 is added.
During the third interval a tone of frequency F3, level L3, and phase P3 is added.
During the first interval a tone of frequency F1, level L1, and phase P1 is played.
