Vocal breaths, the natural sounds of breathing that occur before, during, or after speaking, can be a significant issue in voice recordings. Whether you’re a podcaster, voice-over artist, or musician, these unwanted sounds can detract from the quality of your audio and make it sound less professional. In this article, we’ll delve into the world of vocal breaths, exploring what they are, why they’re a problem, and most importantly, how to get rid of them.
Understanding Vocal Breaths
Vocal breaths are a natural part of human speech, occurring as we inhale and exhale air. When we speak, our vocal cords vibrate to produce sound, and the movement of air through our mouth and nose creates additional noises. These breath sounds can be loud and distracting, especially in quiet moments or when recording in a studio environment. Understanding the causes of vocal breaths is crucial to eliminating them, so let’s take a closer look at the factors that contribute to their presence.
The Anatomy of Vocal Breaths
To comprehend how vocal breaths are produced, it’s essential to understand the anatomy of the human vocal system. The vocal cords, located in the larynx, vibrate to produce sound waves. The movement of air through the mouth and nose creates turbulence, which generates additional noises. The shape and size of the vocal tract, including the mouth, nose, and sinuses, also play a significant role in shaping the sound of our voice and the presence of vocal breaths.
Types of Vocal Breaths
There are several types of vocal breaths, each with its unique characteristics. The most common types include:
Inhale breaths, which occur when we take a breath in before speaking
Exhale breaths, which happen when we release air after speaking
Mid-sentence breaths, which occur when we pause to take a breath during a sentence
These different types of vocal breaths require distinct approaches to elimination, which we’ll discuss later in this article.
Techniques for Reducing Vocal Breaths
Now that we’ve explored the causes and types of vocal breaths, let’s dive into the techniques for reducing or eliminating them. Developing good breathing habits is essential for minimizing vocal breaths, and there are several exercises and strategies that can help.
Breathing Exercises
Practicing deep, diaphragmatic breathing can help reduce vocal breaths. This type of breathing engages the diaphragm, allowing for more efficient oxygenation of the body and reducing the need for frequent breaths. To practice diaphragmatic breathing, lie on your back, place one hand on your stomach and the other on your chest, and inhale deeply through your nose, allowing your stomach to rise while your chest remains still.
Recording Techniques
The way you record your voice can also impact the presence of vocal breaths. Using a high-quality microphone and adjusting your recording technique can help minimize vocal breaths. For example, using a microphone with a cardioid polar pattern can help reject breath sounds, while recording in a room with minimal background noise can reduce the overall noise floor.
Post-Production Editing
In some cases, vocal breaths may be unavoidable, but that doesn’t mean you can’t eliminate them in post-production. Using audio editing software, such as Adobe Audition or Pro Tools, can help you remove or reduce vocal breaths. These programs offer a range of tools, including noise reduction algorithms and spectral editing, that can help you identify and eliminate unwanted breath sounds.
Advanced Techniques for Eliminating Vocal Breaths
While the techniques outlined above can help reduce vocal breaths, there are some advanced strategies that can help you achieve even smoother voice recordings. Using a combination of breathing exercises, recording techniques, and post-production editing can help you eliminate vocal breaths almost entirely.
Multi-Microphone Recording
Using multiple microphones can help you capture a cleaner, more polished sound. By recording with two or more microphones, you can create a blended sound that minimizes vocal breaths. For example, you could use a dynamic microphone for the main vocal sound and a condenser microphone to capture a secondary, breath-reduced sound.
Automated Breath Detection
Some audio editing software, such as iZotope RX, offers automated breath detection tools that can help you identify and eliminate vocal breaths. These tools use advanced algorithms to analyze the audio signal and detect breath sounds, allowing you to remove them with ease.

What are vocal breaths and why are they a problem in voice recordings?
Vocal breaths refer to the audible sounds of breathing that can be heard in voice recordings. These sounds can be distracting and detract from the overall quality of the recording. Vocal breaths can be particularly problematic in voice-overs, audiobooks, and other types of recordings where a smooth and polished sound is desired. When vocal breaths are audible, they can give the impression of a less professional or less polished recording, which can be detrimental to the listener’s experience.
To eliminate vocal breaths, it’s essential to understand the causes of these sounds. Vocal breaths are often the result of poor breathing techniques, such as taking shallow breaths or breathing too heavily. Additionally, the position of the microphone and the recording environment can also contribute to the audibility of vocal breaths. By using proper breathing techniques, adjusting the microphone placement, and optimizing the recording environment, it’s possible to minimize or eliminate vocal breaths altogether. This can be achieved through practice, patience, and attention to detail, resulting in smoother and more professional-sounding voice recordings.
How can I identify and locate vocal breaths in my recordings?
Identifying and locating vocal breaths in recordings can be done by listening carefully to the audio and paying attention to the sounds of breathing. Vocal breaths can be heard as audible inhales or exhales, often before or after a spoken phrase. To locate vocal breaths, it’s helpful to use audio editing software, which can allow you to visualize the audio waveform and zoom in on specific sections of the recording. By examining the waveform, you can identify the areas where vocal breaths are most prominent and take steps to edit or remove them.
Once you’ve identified the locations of vocal breaths, you can use various editing techniques to minimize or eliminate them. This can involve using noise reduction tools, adjusting the gain levels, or manually editing out the breath sounds. It’s also essential to listen to the recording in its entirety to ensure that the edits are seamless and don’t affect the overall flow of the audio. By carefully identifying and locating vocal breaths, you can take the first step towards creating smoother and more polished voice recordings that are free from distractions and imperfections.
What are some techniques for reducing vocal breaths during recording sessions?
There are several techniques that can help reduce vocal breaths during recording sessions. One of the most effective methods is to use proper breathing techniques, such as taking deep breaths and exhaling slowly. This can help to minimize the sound of breathing and reduce the likelihood of audible vocal breaths. Additionally, adjusting the microphone placement and using a pop filter can also help to reduce the impact of vocal breaths. A pop filter can help to diffuse the sound of breathing, while placing the microphone at a slight angle can help to reduce the direct sound of breathing.
Another technique for reducing vocal breaths is to use a consistent recording level and to avoid sudden changes in volume. Sudden changes in volume can accentuate the sound of breathing, making it more noticeable. By maintaining a consistent recording level, you can help to minimize the impact of vocal breaths and create a smoother sound. It’s also essential to take regular breaks during recording sessions to rest your voice and avoid fatigue, which can contribute to more pronounced vocal breaths. By using these techniques, you can reduce the occurrence of vocal breaths and create higher-quality recordings.
Can I use audio editing software to remove vocal breaths from existing recordings?
Yes, audio editing software can be used to remove vocal breaths from existing recordings. Most digital audio workstations (DAWs) and audio editing software programs offer tools and features that can help to minimize or eliminate vocal breaths. These tools can include noise reduction algorithms, spectral editing, and manual editing functions. By using these tools, you can selectively target and remove vocal breaths from the recording, leaving the rest of the audio intact.
When using audio editing software to remove vocal breaths, it’s essential to be careful and precise to avoid affecting the surrounding audio. Vocal breaths can be closely tied to the spoken words, and removing them can sometimes affect the tone, pitch, or rhythm of the speech. To avoid this, it’s crucial to use gentle and subtle editing techniques, such as reducing the gain of the breath sounds rather than removing them entirely. By using audio editing software judiciously, you can effectively remove vocal breaths from existing recordings and improve the overall quality of the audio.
How can I prevent vocal breaths from being recorded in the first place?
Preventing vocal breaths from being recorded in the first place can be achieved by using proper recording techniques and equipment. One of the most effective methods is to use a directional microphone, such as a cardioid or supercardioid microphone, which can help to reject sound from the sides and rear. This can help to minimize the sound of breathing and reduce the likelihood of audible vocal breaths. Additionally, using a microphone with a high pass filter or a low-cut filter can also help to reduce the sound of breathing.
Another way to prevent vocal breaths from being recorded is to adjust the microphone placement and positioning. Placing the microphone slightly off-axis, or at a 45-degree angle, can help to reduce the direct sound of breathing. It’s also essential to position the microphone at a comfortable distance from the speaker’s mouth to avoid picking up excessive breath sounds. By using proper recording techniques and equipment, you can minimize the occurrence of vocal breaths and create higher-quality recordings that require less editing and post-production work.
Are there any specific microphone techniques that can help reduce vocal breaths?
Yes, there are several microphone techniques that can help reduce vocal breaths. One of the most effective methods is to use the “proximity effect” to your advantage. The proximity effect refers to the increase in low-frequency response that occurs when a microphone is placed close to the sound source. By placing the microphone at a distance of around 6-8 inches from the speaker’s mouth, you can take advantage of the proximity effect and reduce the sound of breathing. Additionally, using a microphone with a narrow pickup pattern, such as a supercardioid or hypercardioid microphone, can also help to reject sound from the sides and rear, reducing the sound of breathing.
Another microphone technique that can help reduce vocal breaths is to use a “breath-friendly” microphone placement. This involves placing the microphone slightly above or below the speaker’s mouth, rather than directly in front of it. This can help to reduce the direct sound of breathing and minimize the occurrence of vocal breaths. It’s also essential to experiment with different microphone placements and techniques to find the one that works best for your specific recording situation. By using the right microphone techniques, you can reduce the sound of breathing and create smoother, more polished voice recordings.
Can vocal breaths be completely eliminated from voice recordings, or is some residual sound inevitable?
While it’s possible to minimize vocal breaths significantly, it’s unlikely that they can be completely eliminated from voice recordings. Some residual sound is often inevitable, especially in recordings where the speaker is taking deep breaths or speaking in a soft, gentle tone. However, with proper recording techniques, equipment, and editing, it’s possible to reduce vocal breaths to a level where they are barely noticeable. In fact, some residual breath sound can even be desirable, as it can add a sense of naturalness and authenticity to the recording.
To achieve the best possible results, it’s essential to strike a balance between minimizing vocal breaths and preserving the natural sound of the speaker’s voice. Over-editing or over-processing the audio can sometimes result in an unnatural or robotic sound, which can be just as distracting as audible vocal breaths. By using a combination of proper recording techniques, equipment, and editing, you can create high-quality voice recordings that are smooth, polished, and engaging, with minimal residual breath sound. Ultimately, the goal is to create a recording that sounds natural and authentic, while also being free from distractions and imperfections.
