Lets listen to some more binaural beat samples!

Here we’ve got some beats with a carrier frequency of 330 Hz. The individual frequencies are 20Hz apart, therefor the mathematical beat frequency is 10Hz and the audible is 20Hz.

standard binaural beat, L = 320Hz, R = 340 Hz

the same beat frequency, but in mono

simply 330 Hz, mono, nothing fancy

also 330 Hz, but R and L are of opposite polarity/out of phase

The next samples have a carrier frequency of 165 Hz

binaural beat, L = 160 Hz, R = 170 Hz

the same as mono beat frequency

simply 165 Hz in mono

and 165 Hz out of phase

now it gets interesting. L = 165 Hz, but R sweeps from 165 Hz to 175 Hz, which results in a varying beat frequency

again the same, but in mono.
