These tubes affect how sound waves reach the microphone diaphragm, thus having a huge effect on the microphone’s polar pattern. This is what gives shotgun microphones their length.
In front of the capsule, however, is a long interference tube. To reject sound down to, say, 100 Hz would require a tube 5.5 feet long! Many people think that the length of the tube determines only the overall sound acceptance angle. The longer the tube, the lower the frequency at which the tube is effective in reducing off-axis sound. Interviews are typically shot from about seven to ten feet away from the subject. The most expensive shotgun mics can only capture audio from a distance of six to ten feet, while more affordable mics sound their best at a distance of three to four feet away. How far should shotgun mic be from subject? In scenarios such as these, the speaker does not need to hold a microphone and speak into it or wire a microphone on his body in order to record his speech or lecture. What are shotgun mics good for?Ĭommon uses of shotgun microphones are for talks or speeches in meetings, conferences, and lectures. Shotgun mics aren’t built to be held in the hand, but many reporters do it and end up with handling noise on their recordings. Shotgun mics (and many other condensers) are susceptible to handling noise.

You have seen a film or TV show that was made with Shotgun behind the scenes. Shotgun is the industry standard for film, TV and game production management. Lavaliers attach to an actor’s clothing, usually the lapel. These are usually called “LAVs” or “body mics”. The microphone type that is often in use are lavalier microphones.
