bi-directional microphone : A figure-eight microphone.
omnidirectional microphone : (Omni) A pressure operation microphone with a non-directional acceptance angle, i.e., one that is spherical, usually called an omni. See directional cardioid microphone.
unidirectional microphone : Any microphone in which the pick-up pattern exhibits more sensitivity to sounds approaching on-axis, i.e., any variation of the cardioid pattern, s. Such as a supercardioid or hypercardioid. See also directional microphone, omnidirectional microphone, polar pattern.
directional microphone : A microphone which does not have a spherical polar pattern, i.e., a microphone which is not omnidirectional, such as a cardioid, figure-eight, etc. having an acceptance angle of less than 360вк. See directivity.
