Definition of cardioid in English:
1A heart-shaped curve traced by a point on the circumference of a circle as it rolls around another identical circle.
- M is the point of the moving circle that traces the cardioid.
- The caustic of a circle with radiant point on the circumference is a cardioid, while if the rays are parallel then the caustic is a nephroid.
- For the special case of b = a, the result is a two-dimensional heart-shaped curve known as the cardioid.
1.1 (also cardioid microphone) A directional microphone with a heart-shaped pattern of sensitivity.
- These microphones are invariably cardioid microphones, meaning that the shape of the sound sensitive field around the mike is in the shape of a heart, essentially picking up sound in both forward and side directions.
- DPA calls this mic a wide cardioid, and, indeed, between 500 Hz and 10k Hz, the 4015's polar response begins to resemble an omni mic.
- For the upright, I used two mics: one cardioid large-diaphragm near the floor, pointing up at the bridge, and the xt up closer to the players' right hand to capture more of the string noise and attack.
