[phasor~] can be thought of as a cycling counter. It counts up to 1 and 
then instead of giving a 1 it drops to 0 and starts again. This can be 
used to loop through a recorded sound in a table.

In the case of a table-based delay line, you have to be continually 
writing in the table. In the case of a constant delay, this means that 
each sample will be read only (and exactly) once before it is replaced by 
something newer, and this means that the frequencies of the two phasors 
will be the same, but their phases will be different.

You can also replace two phasors with just one if you add a [+~] and a 
[wrap~]. That's especially useful in your case.
