selecting a microphone capsule for product integration, cardioid is often the first choice for many engineers. But wide cardioid exists for a reason: some acoustic sources simply do not fit within a cardioid pickup pattern. This guide explains wide cardioid&#8217;s characteristics, when it is the better choice, and what OEM designers need to consider when integrating wide cardioid capsules into their products. 1. What Is Wide Cardioid? Microphone pickup patterns are not limited to a few fixed categories. They exist along a spectrum from omnidirectional to highly directional patterns. Wide cardioid falls between omnidirectional and cardioid \u2014 more directional than omni, less focused than cardioid.
