What defines a cardioid?

: a heart-shaped curve that is traced by a point on the circumference of a circle rolling completely around an equal fixed circle and has an equation in one of the forms ρ = a(1 ± cos θ) or ρ = a(1 ± sin θ) in polar coordinates.

What is a microphone pattern?

A microphone’s polar pattern is the sensitivity of how well the microphone receives sound relative to the angle or direction of where the sound originates. In simpler terms, a microphone’s polar pattern is how well the microphone can capture sound from various directions.

What is a cardioid pick up pattern?

A cardioid pickup pattern is a highly flexible pickup pattern that is great for all-purpose use. A cardioid mic, while slightly directional, should not be confused with a hypercardioid or supercardioid mic. Cardioid mics will still pickup background noise if they are not in a controlled environment.

How is the shape of a cardioid defined?

Cardioid. A cardioid is a two-dimensional plane figure that has a heart-shaped curve. The word “cardioid” originated from a Greek word, which means “heart”. Hence, it is called a heart-shaped curve. The shape of a cardioid can be compared to the cross-section of an apple excluding its stalk. In Mathematics, we study different types

How is a microphone shaped like a cardioid?

Cardioid. A cardioid microphone exhibits an acoustic pickup pattern that, when graphed in two dimensions, resembles a cardioid, (any 2d plane containing the 3d straight line of the microphone body.) In three dimensions, the cardioid is shaped like an apple centred around the microphone which is the “stalk” of the apple.

How is a cardioid formed in a polar coordinate system?

The cardioid is formed by following the path of a point on a rolling circle over another fixed circle of the same radius. There is one cusp in the cardioid. Usually, a Cardioid is represented in the polar coordinate system, but it may also be shown in the Cartesian system. The graph of a cardioid is demonstrated below:

Which is better a supercardioid or a cardioid pattern?

Supercardioid is more directive than a cardioid pattern having a bit more side and a bit less rear rejection. It is advantageous in live situations as it allows for very high gain before feedback. It also keeps the signal very dry; you get mainly the direct signal from your sound source.
