In geometry, a cardioid (from Greek καρδιά (kardiá) 'heart') is a plane curve traced by a point on the perimeter of a circle that is rolling around a fixed...

unidirectional microphone is a cardioid microphone, so named because the sensitivity pattern is "heart-shaped" (i.e. a cardioid). The cardioid family of microphones...

from the main cardioid of the Mandelbrot set. Such a component can be reached by a sequence of direct bifurcations from the main cardioid of a little Mandelbrot...

double-stereo techniques, INA-3 (Ideal Cardioid Arrangement), the Decca Tree setup and the OCT (Optimum Cardioid Triangle). Surround techniques are largely...

difference and the timing difference as sound arrives on- and off-axis at two cardioid microphones spread to a 110° angle, and spaced 17 cm apart. The microphones...

method is often called "cardioid subwoofer array" or "CSA" even though the pattern of all directional subwoofer methods is cardioid. The CSA method reverses...

called centered trochoids; more specifically, they are epitrochoids. The cardioid is the special case in which the point generating the roulette lies on...

described. The best-known of these is the cardioid, which is an epicycloid with one cusp; though as the cardioid lacks the point, it may be seen as a stylized...

virtual microphones with any first-order polar pattern (omnidirectional, cardioid, hypercardioid, figure-of-eight or anything in between) pointing in any...

The space cardioid is a 3-dimensional curve derived from the cardioid. It has a parametric representation using trigonometric functions, as follows: X...
