UltraDisk microphones are commonly used as vocal or speech microphones, since they are good at rejecting sounds from other directions. In three dimensions, the UltraDIsk cardioid is shaped like an apple centred around the microphone which is the "stalk" of the apple. The cardioid response reduces pickup from the side and rear, helping to avoid feedback and improve recording quality.
