You have already seen a microphone filter in videos or photos. It’s that object positioned in front of the speaker’s microphone.
What is a Podcast Microphone Filter, and What does It Do?
A pop filter is a mesh screen with a circular pattern placed in front of the microphone before recording. The pop filter’s purpose is to remove popping noises from voice recordings, as the name suggests.
When you speak consonants like Ps, Ts, and Bs directly into the microphone, you will hear popping noises, also known as plosives. A burst of air strikes the microphone as you make these noises, making your voice “pop out” in the recording. You wouldn’t want it in your recording because it is harsh to hear. The same holds for microphone laughter. The microphone would pop due to the air pressure.
Human speech naturally includes plosives. Simply put, you need to filter them out in a voice recording because the process amplifies them. On a condenser mic, the effect is more noticeable, and the proximity effect makes the plosives sound highly harsh. Therefore, always use a pop filter to get a clear recording while recording indoors. Pop filters made of nylon are inexpensive and straightforward to set up.
Pop-Filter or Foam Filter
Many new podcast producers frequently wonder whether they should use a pop filter, a foam filter, or both. For a more precise understanding, let’s compare the two pieces of equipment.
Plosives are eliminated by a pop filter, and the foam shields the microphone capsule from the wind. These are two distinct tasks that cannot be performed in place of one another. The mic is not shielded from the wind by a pop filter. Additionally, foam filters only partially reduce plosives.
Although a pop filter is crucial to the recording process, you cannot set one up outside or while recording on the go. In this case, you would have to make a small concession to get a clean recording and only use your mic foam.
Both pop and foam filters have their benefits and shortcomings. Each has distinctly different jobs for improving the sound quality of your audio recording. You can explore more and learn the difference here to make an informed decision.
Benefits of Microphone Filters
Apart from the purpose mentioned above, the filter’s secondary function is to stop vocalists’ saliva from entering the microphone. This gives using a microphone filter an additional thumbs up. A filter helps the microphone last longer. Even though it’s not much, it can prevent your microphone from disintegrating and smelling bad.
Microphone Filter Placement
The closer the microfilter and pop filter is, the better the vigor of you or the other speaker but keep in mind that they don’t touch each other. Placing the filters and pops in a certain position will prevent noise explosions.
If you’re recording a peaceful, intimate setting, place the pop filter at a certain distance from the vocal. You must experiment to determine the best distances for the room’s ambiance and when the vocals are in your mix. Learn about the style and sound levels of the podcast you will be recording. The filter will work best if the performer’s mouth and microphone capsule are in the correct position.
Types Of Filter
There are three main categories of pop filters available.
- Nylon filters: Pop filters made of woven nylon stretched around a spherical frame are popular. Pop filters made of nylon mesh are affordable and efficient. Using this pop filter during recording sessions may lower some high frequencies.
- Metal filters: Metal mesh pop filters are an additional well-liked option. This particular pop filter is constructed from a metal screen. Metal pop filters are more expensive than nylon mesh pop filters, but they still filter out or reduce plosive sounds while allowing a more comprehensive range of frequencies to pass through.
- Foam windscreens: Foam windscreens directly enclose microphones. Foam windscreens are helpful for outdoor boom microphones and condenser microphones that clip onto a speaker’s clothing. Foam windscreens, which are frequently too close to the microphone to function properly, are less effective at reducing plosive sounds than nylon mesh and metal mesh pop filters.
Simple Pop Filter
You don’t need to spend much money to get professional sound because the tools and methods required to produce a professional-sounding podcast are reasonably priced. However, you do need a good microphone and a good room.
A typical do-it-yourself pop filter involves stretching a pair of leggings or stockings over a metal coat hanger bent into a circle shape. The stockings serve as a double layer of the acoustically semi-transparent material, and the coat hanger serves as the frame. These commonplace items function admirably as efficient pop filters.
As microphone filters can change the dynamics of your podcast experience for your listeners, enhancing your audio quality can be a smart way to create quality content anywhere, anytime, as most podcast listeners usually listen while performing everyday chores.
