Plosives are consonant sounds that occur when the air from the vocalist hits the microphone’s capsule with excessive force, resulting in a popping or booming sound. Common examples of plosives are the “Pa,” “Ba,” and “Fa” sounds.
The main causes of plosives are the release of air during the pronunciation of certain consonants, particularly those that require a heavy breath. When these sounds are produced, the forceful burst of air can overload the microphone’s capsule and create unwanted audio artifacts.
To better understand plosives, it’s helpful to consider their phonetic classification. Plosives, also known as stop consonants, are characterized by a complete blockage of airflow in the vocal tract followed by a sudden release. This results in a sharp burst of sound and air pressure that can cause issues in recordings.
In order to effectively eliminate plosives from recorded audio, it’s important to have a clear understanding of their nature and how they are formed. By recognizing the specific sounds that contribute to plosives and the underlying causes, we can implement strategies to minimize their impact and ensure clean, professional-quality recordings.

Removing Plosives with Filters
One effective technique for removing plosives from recorded audio is to use filters. By using low-cut filters or high-pass filters, it is possible to attenuate the bass frequencies that plosives typically occupy. This helps in reducing the energy of the plosive, resulting in a less noticeable pop or boom sound. It is important to exercise caution while implementing this technique to avoid cutting too much of the vocal’s natural low end, which can adversely affect the overall sound quality. To achieve a more precise reduction of plosives, it is recommended to use a 24dB per octave slope. The implementation of filters can significantly enhance the audio quality by eliminating plosives in post-production.
In addition, I would like to highlight an important point for consideration. While filters are effective in removing plosives, they may also impact the overall frequency balance of the audio. Striking the right balance between plosive reduction and preserving the natural characteristics of the vocal is crucial. It is essential to make adjustments and fine-tune the filter parameters to achieve the desired result without introducing any unwanted artifacts.
Using low-cut filters, high-pass filters, and other plosive removal techniques in audio post-production can greatly enhance the quality of recorded sound. The application of these techniques allows for the reduction of plosives, resulting in clear and professional audio output.

Attenuating Plosives with Dynamic EQ
Another effective technique for reducing plosives in recorded audio is using a dynamic EQ. This specialized tool allows for precise control over the specific frequencies occupied by plosives, while preserving the natural characteristics of the vocal.
A dynamic EQ works by setting a threshold that determines when the EQ will be activated to attenuate the plosives. By adjusting the sensitivity and strength parameters, you can fine-tune the dynamic EQ to only trigger when plosives occur, effectively reducing their impact on the audio.
While a dynamic EQ may not always be as straightforward as using a low-cut filter, it offers a more nuanced approach to plosive removal. By targeting the specific frequency range of the plosives, you can minimize their presence without compromising the overall sound quality.
The key to successful plosive reduction with a dynamic EQ lies in careful threshold settings. Setting the threshold too high may result in incomplete removal of plosives, while setting it too low may introduce unwanted artifacts and affect the natural timbre of the vocal. It’s essential to experiment with different threshold levels to find the right balance for your particular recording.
When utilizing a dynamic EQ, it’s important to take into account the preservation of vocal characteristics. Unlike other methods that may lead to a loss of natural tone, a dynamic EQ allows for more targeted control, ensuring that the vocal’s unique qualities are maintained while addressing plosives.
“By using a dynamic EQ, I was able to precisely attenuate the plosives in the recording, while preserving the vocalist’s raw and emotive performance. It’s an invaluable tool for achieving a clean and natural-sounding audio without compromising the artistic integrity of the vocal.”

Best Practices for Preventing Plosives
While post-production techniques can help eliminate plosives, it’s always best to prevent them during the recording process. By following these best practices, you can minimize the need for extensive plosive removal in post-production.
Proper mic placement is crucial for preventing plosives. Ensure that the vocalist’s breath doesn’t directly hit the microphone’s capsule. Position the microphone slightly above or below the vocalist’s mouth, angled slightly off-axis to capture the vocals while minimizing the direct impact of breath. This positioning can help reduce the occurrence of plosives by avoiding direct air pressure on the microphone.
Using pop filters or windscreens can be highly effective in minimizing plosives. These devices are specifically designed to diffuse the blast of air from plosive sounds, reducing their impact on the microphone. Place the pop filter about two inches in front of the microphone, positioning it between the vocalist and the microphone’s capsule. This physical barrier helps to disperse the air pressure and prevents it from directly hitting the microphone, resulting in cleaner audio with fewer plosives.
Techniques for Preventing Plosives
Employing a low roll-off before compression can also help prevent plosives from being captured during the recording process. A low roll-off filter reduces the low-frequency content in the vocal signal before it reaches the compressor, minimizing the chances of plosives triggering excessive compression. This technique can be effective in reducing plosives without compromising the vocal quality.
By implementing these best practices, you can significantly reduce the occurrence of plosives during recording. Proper mic placement, the use of pop filters, and employing a low roll-off filter are key techniques for preventing plosives and ensuring clean and high-quality audio.
