How to find the beat frequency between two waves
An alternative way to find the beat frequency between two waves using ASPL playop on the differential
group variable holding the waves as the frequencies are slightly shifted.
The script wavesbeat2.pl can find when two waves intersect along their
summed areas. The script iterates by slightly incrementing the frequency of one wave, then
get the intersection of both waves along their summed areas (using the playop operator on the group union), hence locating these
points of intersection where the beats occur.
