![]() ![]() ![]() The bright side is that you don’t need to aim an omnidirectional microphone at the source of the sound. This means they evenly pick up sound from 360 degrees. Omnidirectional microphones are equally sensitive to sound from every direction. However, it is harder to place and aim these microphones accurately. They are the most common choice for live streaming, as they block sounds such as a loud fan or the clatter of your mechanical keyboard.Ĭardioid subtypes, known as super-cardioid and hyper-cardioid, have narrower sound sensibility angles and a greater ability to reject ambient sound. Cardioid microphones isolate unwanted ambient sound, as well as any other unwanted sounds, from the back of the microphone. A classic cardioid microphone picks up the sound from the front. The three polar patterns you need to know are cardioid, omnidirectional and bidirectional. Simply put, a polar pattern is the ability of a microphone to pick up your voice from different angles. Polar patternĪ polar pattern, also known as directional property, is the inherent sensitivity to the direction of audio waves. Anything lower or higher than these spectrum extremes is pretty much useless, as the human voice simply cannot produce such frequencies. Typically, the golden standard for frequency response is from 20 Hz to 20,000 Hz. It’s measured in hertz (Hz) and kilohertz (kHz), from the lowest frequencies to the highest. Frequency responseįrequency response is the range of voice frequencies your microphone can pick up. ![]() Here are four characteristics to consider when choosing a microphone for live streaming. ![]()
