What is a plosive?

Plosives are specific speech sounds, which come from saying letters like "t", "k" or "p". When you pronounce these letters, you naturally expel a quick gust of air while enunciating. Think of the word "pickles." When you pronounce this word into a microphone, you will record the word, but just like the first letter says, the microphone will capture that gust of air as sounds. It is usually a deep bass sound with high amplitude. This can be harmful to your listeners or spectators when they hear it.

How to fix audio plosives?

There are a couple of ways to fix them. The best solution is to consider how you or your talent speak into the microphone. A windshield or pop filter is also an easy way to reduce explosive recording. Moving the microphone away from talent can help, but you run the risk of audio levels being too low. Or, depending on the microphone, you can place the microphone directly on the lips of the talent to interrupt the air explosion. Have you ever seen musicians on stage singing in a microphone with their lips in the microphone? There's a reason for that.

However, if you have to fix the plosives in the publication, Adobe Audition makes it easy with the FFT filter effect. Audition allows you to see the audio waveform. In most cases, the plosive will be easily visible as the waveform increases. See Figure A for an example.

Once you identify the plosive, you can reproduce it just to be sure. Again, it will sound as if the air enters the microphone.

Now, let's eliminate the plosive. First, use the time selection tool ("t" on your keyboard) and highlight the problem area of ​​your audio. If you have difficulty selecting the audio range, you can zoom in on the timeline by moving the mouse wheel for a better view ( Figure B ).

Navigate to the FFT filter through the Effects menu and select Filter and EQ, then select FFT Filter ( Figure C ).

The FFT filter has several built-in presets. Specifically, there is a preset called "kill the mic rumble" ( Figure D ).

This is the perfect preset to use to fix the occlusives found in the dialogue audio. After selecting the preset, simply click on the Apply button. You will notice that its waveform will change and the peak will be reduced ( Figure E ). After playback, you will hear that the explosive is minimized.

There you have it. Removing audio plosives is as easy as a few clicks of the mouse or keyboard shortcut. Of course, the key is to minimize plosives before recording, but if they are captured, you can solve them with Adobe Audition.
