## mic_polaritypatterns.jpg

The image displays a set of polar plots representing different types of microphone pickup patterns used in audio recording. Each plot is labeled with a specific name indicating the type of pattern it represents: Cardioid, Omni, Bi-directional, Shotgun, Supercardioid, and Hypercardioid.

- **Cardioid**: This plot shows a heart-shaped pattern where sound is picked up best from the front (0 degrees) and gradually decreases as you move towards the sides. The sensitivity drops significantly behind the microphone.
  
- **Omni**: This plot indicates that the microphone picks up sound equally well from all directions, forming a circle around it.

- **Bi-directional**: This pattern captures sound primarily from two opposite directions (front and back) while rejecting sounds coming from the sides. It is shaped like a figure-eight.

- **Shotgun**: The shotgun pattern is highly directional, capturing sound best directly in front of the microphone with very little pickup from behind or to the side. It resembles an elongated ellipse pointing forward.

- **Supercardioid**: This plot shows a more focused pattern than cardioid but less so than hypercardioid. It picks up sounds well from the front and sides, with some rejection towards the back.

- **Hypercardioid**: Similar to supercardioid, this pattern is highly directional, capturing sound best directly in front of the microphone while rejecting sounds coming from behind more effectively than cardioid but less so than shotgun patterns. It has a shape that resembles an elongated ellipse pointing forward with some rejection towards the back.

Each plot includes a scale ranging from -60 dB to 0 dB on both axes, which represents the relative sensitivity or gain of the microphone in decibels (dB). The angles are marked at intervals of 90 degrees around the circle.
