Thanks Julius and Spencer for your suggestions. I think I have a better handle now, but still reading and reading and reading (and taking rather too long to reply). Stuart On Fri, May 23, 2014 at 11:16 PM, wrote:

I like to think of phasing as an approximation to and generalization of flanging, which is easier to understand. In both cases you are basically mixing two copies of the input signal where one copy is delayed relative to the other. This relative delay causes cancellation ("notches") at frequencies where the two signals are out of phase.

Honestly it can take a few readthroughs (of different books even) for it all to sink in.

Julius also some discussion on implementing a phaser: https://ccrma.stanford.edu/~jos/pasp/Virtual_Analog_Example_Phasing.html and (related, simpler) flanging: https://ccrma.stanford.edu/~jos/pasp/Flanging.html
