Do I Need A Pop Filter?

Our listeners would never want to listen/watch distorted audio/video from any song/music, voiceovers, etc. Lousy audio is like having termites; we don’t see the damage being done while it’s happening.

We don’t see it undoing all the other good work we’ve done, and when the shooting is over, it’s usually too late to save the audio. 60% of the perception of the quality of a video comes from the quality of the audio. So, let’s fix the problem.

While using a microphone, many of us don’t bother to use a pop filter. That makes our voice a little bit annoying because of the distortion in the audio. What are the reasons to use a pop filter?

Why Do Popping Sounds Occur?

One of the challenges we face when we’re recording vocals is controlling plosives. Our P’s B sounds that result in a puff of air that comes across as a big thump in the microphone signal those thumbs are challenging to remove after the fact; you can’t balance them out; for example, the best resolution for plosives is to use a pop filter. It is a screen made of fabric, metal, or foam that diffuses that puff of air and prevents it from coming by and jostling its diaphragm.

A pop filter dramatically lessens the effects of plosives on our signal. We don’t get those big thumps in the bottom, and we don’t have to bother about filtering or queuing those out; we get a clean, pristine vocal sound.

What Are Plosives?

When you get closer to the microphone, you start to encounter something called plosives. Plosives are the first group of sounds that beatboxers make.

They make them by stopping the airway on releasing the sound out. There are different kinds of plosives that you could make with a human mouth by blocking the sound with other parts of your mouth’s anatomy.

  • The first kind of plosive is (B) called the bi-labial plosives, which means two lips, as b is spelled with two lips.
  • The second kind is (p) called The bi-labial plosive.
  • The third one is (k) (g) Both vocal tract plosives.
  • Another plosive is (t)- Teeth and alveolar ridge.
  • The plosive sounds different because you are using other parts of the anatomy in the mouth.

What Does A Pop Filter Do?

So, when it comes to using any microphone, having some filter or pop filter is very important, mainly because of what are called plosives, which we mentioned earlier. First of all, A pop filter helps eliminate the plosives, and the other reason, it prevents the mic. from being corrosive because of the vocalist’s saliva.

Tech Tips for Pop Filter

A pop filter is a piece of equipment every YouTuber, podcaster and any audio enthusiast should have in their recording arsenal. Not only does it fix an annoying audio problem, but there’s also an inexpensive way to improve your audio quality.

Most pop filters considerably come with a clamp that allows you to secure to any microphone stand. The pop filter itself is generally connected to the clamp via a gooseneck so you can place the pop filter anywhere you want for vocal recordings.

Pop filters typically work best when placed about six inches away from the microphone, with the source of the audio bow a foot away from the microphone itself. In other words, when you’re recording vocals, the person speaking or singing should be about a foot away from the microphone with the pop filter placed right in between the person and the mic.

Pop is a burst of air that results when individual letters are spoken or sung, such as the B, T, and P.

When a blast of air hits a pop filter, it gets broken down into slower, less powerful bursts. However, pop filters not only break up the airburst in the smaller ones, but because of how they are designed, the pops are also diffused in two different directions, so few, if any, reach the diaphragm of the microphone.

While the pop shield is for preventing your breath from creating a “pop” when using certain words, especially those beginning with “p” – this is a more explosive expiration of air and cause.

Advantages Of Pop Filters

  • Pop filters are excellent for indoor use.
  • Using a pop filter cuts out problems on both the high and low ends, making it simpler to edit out undesired sounds and frequencies.
  • They reduce the popping sounds caused by the mechanical impact of fast-moving air on the microphone.
  • They aid to minimize plosives like Ps and Bs and can cut down on sibilance.
  • Pop filter vs. foam: The foam filter is mainly to avoid light air movement noise.


The pop filter makes it easier for the audience to hear you without any distort. If you are working in an enthusiastic audio background, make sure to use it before regretting listening to a pop sound.

A good pop filter will ensure that your recordings’ focus is the excellent sound quality and that any unwanted noises are filtered out and not picked up by your microphone.

An obvious solution for avoiding plosives would be to back off the microphone slightly off-axis. You can either keep the mic below the pointing up or pointing down.
