Flanger
This device was built from a c74 mps tutorial on flanging. Here is a summary of the info from the tutorial.
When a signal with a time-varying delay (especially a very short delay) is added together with the original undelayed signal, the result is a continually varying comb filter effect known as flanging. Flanging can create both subtle and extreme effects, depending on the rate and depth of the modulation.
The output of cycle~ is multiplied by 0.25 to scale its amplitude. That signal is multiplied by the basic delay time of 100 ms, to create a signal with an amplitude ±25. When that signal is added to the basic delay time, the result is a signal that varies sinusoidally around the basic delay time of 100, going as low as 75 and as high as 125. This is used to express the delay time in milliseconds to the tapout~ object.
Flanging usually happens at no more than 20ms delay and you are modulating the delay time here continuously.

FormantFilter

Formants are resonant frequencies in the vocal tract that we associate with vowel sounds. Here this process is recreated using 3 resonant bandpass filters, boosting the three most distinctive frequencies associated with common vowel sounds.
The frequencies here were taken from the average vowel formants for a male voice (in Hz) found on https://en.wikipedia.org/wiki/Formant
