   <p>
   A Flanger is a specialized kind of delay that uses an LFO (low frequency oscillator) 
   to vary the amount of delay applied to each sample. This causes a sweeping frequency 
   kind of sound as the signal reinforces or cancels itself in various ways. In particular
   the peaks and notches created in the frequency spectrum are related to each other in 
   a linear harmonic series. This causes the spectrum to look like a comb and should be
   apparent in the visualization.
   <p>
   Inputs for the Flanger are:
   <ul>
   <li>delay (in milliseconds): the minimum amount of delay applied to an incoming sample</li>
   <li>rate (in Hz): the frequency of the LFO</li>
   <li>depth (in milliseconds): the maximum amount of delay added onto delay by the LFO</li>
   <li>feedback: how much of delayed signal should be fed back into the effect</li>
   <li>dry: how much of the uneffected input should be included in the output</li>
   <li>wet: how much of the effected signal should be included in the output</li>
   </ul>
