From microphone polar patterns to various microphone types and accessories, choosing the right equipment is the first step to clear and clean recordings.

Through this guide, select the right microphone for you and elevate your audio production skills to the next level!

🎙️ Essential Equipment for Recording: All About Microphones!

The most basic equipment needed for recording is a microphone.

A microphone plays the role of converting sound into electrical signals for recording, and it comes in various types and characteristics.

Key Microphone Characteristic: Polar Pattern

While microphones have various characteristics, understanding ‘polar pattern’ is very important.

Polar pattern indicates how well a microphone picks up sound from different directions.

• Cardioid:

  Picks up sound best from the front of the microphone. Dynamic microphones are primarily cardioid. When using, it’s recommended to position the microphone directly facing you. If positioned sideways, almost no sound will be picked up. It is suitable for single-person recording and helps reduce ambient noise.

• Bi-directional:

  Picks up sound well from both the front and back of the microphone. Useful for recording conversations between two people facing each other, such as interviews.

• Omnidirectional:

  Picks up sound evenly from all directions (360 degrees) around the microphone. It is advantageous for recording sounds in large spaces or conversations involving multiple people, but it can also pick up ambient noise.

  • Smartphone Microphone Polar Pattern: Smartphones primarily use omnidirectional microphones. This is to pick up sound from any direction. Because of this, when recording with a smartphone, if you hold the microphone too close, it might lead to popping sounds or degraded sound quality.

• Supercardioid/Hypercardioid:

  Picks up sound from a narrower range and more focused direction than a cardioid microphone. Used for minimizing external noise and clearly capturing the sound of a specific subject. It is used in drama sets or journalist interviews to clearly capture distant sounds or specific individuals’ voices.

Microphone Types

There are various microphone types depending on the recording purpose and environment.

• Dynamic Microphone:

  A common microphone seen in karaoke. It is robust, relatively inexpensive, and used in various situations like live performances or lectures. It primarily has a cardioid polar pattern.

• Lavalier Microphone (Lapel Microphone):

  A small microphone worn on clothing or the body. Used in lectures, interviews, and broadcasts. Lower-priced microphones in the market tend to be cardioid, while higher-priced ones tend to be omnidirectional. Omnidirectional microphones are mainly used when musical actors wear microphones on their forehead or side.

• Condenser Microphone:

  The most commonly used microphone in recording studios. It can pick up delicate sounds and is used for recording singers or voice actors. It is often hung upside down. Condenser microphones have an exposed diaphragm and can be cardioid, bi-directional, or omnidirectional. Products are available that allow you to change the polar pattern depending on the price range.

• Gooseneck Microphone:

  A microphone with a flexible neck. Named because it resembles a ‘goose neck’. Designed for easy ON/OFF switching by speakers in meetings or hearings. It is likely to be cardioid.

• Shotgun Microphone:

  A long, slender microphone specialized in picking up sound from a specific direction. Used in drama filming or journalist interviews to clearly capture distant sounds or specific individuals’ voices. It is typically a supercardioid microphone and has the characteristic of picking up less external noise.

• Stereo Microphone:

  Has two microphones that pick up left and right sounds separately, allowing for three-dimensional sound. It is often used in ASMR content creation.

Accessories

In addition to microphones, there are accessories that help improve recording quality.

• Microphone Stand:

  Comes in various forms: floor stands for standing, table stands for sitting, and articulated arms that attach to desks. Choose a stand suitable for your environment.

• Pop Filter:

  Reduces ‘popping’ sounds (plosives) that occur when air forcefully bursts out from pronunciations like ‘p’ or ‘b’ directly into the microphone. It is the round disc shape used in radio broadcasts or singer recordings.

• Shock Mount:

  Primarily used with condenser microphones. It absorbs vibration sounds transmitted to the microphone (e.g., sounds from hitting the desk or stomping feet) to prevent them from being recorded. It uses rubber bands to dampen vibrations. It is essential for preventing vibration sound input due to the sensitive nature of condenser microphones.

• Windscreen:

  Prevents wind sound from being recorded by the microphone. It is used to effectively block noise like ‘dadadada’ caused by wind hitting the microphone during outdoor recording, ensuring clear voice pickup. It is often seen as a furry accessory in outdoor entertainment shows or drama filming.

Monitoring and Talkback Systems

Systems for checking sound and communicating during recording.

• Monitoring System:

  A system that allows you to listen to and adjust recorded audio signals in real-time. It is useful for checking your voice status and can also be used for recording while listening to music. It might feel uncomfortable at first, so you can choose whether to wear it as needed.

• Talkback System:

  Primarily used in recording studios, it’s a system where a director or producer outside the recording booth can communicate with the person being recorded in real-time via a microphone.
