A hypercardioid mic is like a supercardioid on steroids; the front pickup angle is even narrower and focused, which results in greater rejection of unwanted noise and feedback. To give you an idea, the typical pickup angle on a supercardioid mic is around 115 degrees, whereas a hypercardioid can be as low as 105 degrees.
The output of this filter gives data at a lower sample rate, typically between 16 and 48 kHz. A microphone with an I2S output, like the ADMP441, has all of the same pieces of the signal chain as the PDM chain, but the places where each piece is implemented is slightly different.
