Understanding sound quality is an important part of producing quality video content.

The overall sound experience you create in your videos directly contributes to the emotional response viewers have while watching, so having a working understanding of sound quality is key to ensuring that your videos reach their full potential.

In this guide, we will discuss what sound quality is and how it’s measured, as well as the various factors that contribute to getting the best audio for your projects.

What is Sound Quality

We’ll start by looking at how we measure audio, including definitions for several major measurements of sound quality such as frequency range, dynamic range and noise floor. After that, we’ll cover strategies to ensure good sound capture, including techniques for optimizing on-set conditions and tips to minimize noise interference during audio-only recordings. We’ll also look at ways post-production can affect your final product and finish up with a brief overview of some well-known potential pitfalls when it comes to achieving top-notch audio for your projects.

Definition of Sound Quality

Sound quality is a measure of the clarity, richness, and fidelity of audio in a recording or broadcast. It is an assessment metric that is often used in the video production industry to determine the effectiveness of the audio in a project. Sound quality is an essential part of producing quality video content, as it can determine the overall quality of the viewer’s experience. Here, let’s discuss what sound quality is in detail and how it can impact the quality of a video.



Frequency is the measure of how many times a sound wave repeats itself in a second, and is measured in Hertz (Hz). Humans are generally able to hear sounds between 20 Hz and 20 kHz. A frequency that falls within this range is referred to as an audible frequency. Sounds with frequencies below 20 Hz, known as infrasonic frequencies, are usually only felt rather than heard. Those with frequencies above 20 kHz are called ultrasonic.

In video production, certain frequencies can be more important than others. Commonly referred to as “listening sweet spots”, these audible ranges allow viewers to differentiate different instruments and voices in an audio mix better. They also give more space for elements such as effects and transitions, so the overall mix maintains its clarity throughout the entire video presentation. To make sure that your audio is clear and natural-sounding at all times within its frequency range, it’s best to monitor your audio levels when mixing in post-production.

Bit Depth

When it comes to sound quality, the bit depth of the audio is a major factor. Bit depth is measured in bits, and higher values indicate an increased dynamic range – enabling producers to capture a wider range of sounds. The higher the bit depth value, the better, as it allows more space to represent levels and nuances in sounds such as footsteps or whispers. Typical industry standard bit depths are 8-bit and 16-bit; however, 24-bit audio offers up significantly more dynamic range. It enables users to record louder and softer sounds accurately without interference from background noise which can often occur when recording with lower bit depths.

For spot recordings or transitions between clips, 24-bit audio will provide superior sound quality for your video production projects. While higher bit depths such as 32-bit are possible for some applications, their uses are mainly limited to professional sound studios. No matter what type of project you’re working on though, prioritizing bit depth should be a priority for those who want their videos to stand out from the competition.

Dynamic Range

Dynamic Range is a measure of the difference in volume between the loudest and softest sounds that can be reproduced by an audio system. The greater the Dynamic Range, the more ability a sound system has to produce both loud and soft sounds. For example, if you had a card game with both low and high playing cards, you would need a bigger range of poker chips to make sure your bets could cover all scenarios. With audio, the higher dynamic range allows for a wider range of volume levels to be accurately reproduced which helps add more dynamic excitement for the listener – whether it’s an orchestra performing in a grand concert hall or enjoying your favorite film at home. In video production, having higher Dynamic Range enables engineers to capture and reproduce sounds that would otherwise sound flat or be drowned out by background noise without losing any of their detail or richness. Audio with wider dynamic range adds extra distinction in musical works, lifelike details across dialogue narration and stunning realism when watching videos on-screen.

Sound Pressure Level

Sound Pressure Level (or SPL) is a measure of the strength or intensity of sound relative to a reference level. To put it simply, it’s the loudness of sound measured in decibels. It’s important to note that the distance from the source is also a factor—the further away you get, the quieter the sound gets due to absorption and other factors.

The sound pressure level is affected by both sound pressure and amplitude, which are closely related; however, amplitude refers more broadly to any variation in pressure caused by waves, while SPL focuses on variations caused by audible sounds. To precisely measure SPLs beyond 15 dB (which is considered audible), sensitive microphones and amplifiers must be used because they can detect even subtle fluctuations in air pressure caused by certain frequencies or tones.

Various industries have their own standards for safety when it comes to exposure levels for long periods of time (an 8-hour day at work). For video production specifically, this generally falls within 85-95 dB range. Using an SPL meter can help determine appropriate safety measures such as taking breaks or wearing ear protection if necessary. Additionally, proper microphone technique can help reduce excessive noise during production—using foam windscreens, placing directional mics closer to sources when appropriate, etc.

Factors that Affect Sound Quality

Sound quality is an important component of any video production. It is important to understand the factors that affect sound quality and how they should be addressed. This section will explore different aspects of sound quality and the techniques that can be used to improve it. Let’s dive into the details.

Room Acoustics

The acoustics of the room you’re recording in can have a major impact on the overall sound quality. The shape, size, and design of a room can affect how sound waves interact with each other and distort the recording.

For instance, a smaller room will have more reflections and reverberation than a larger one because the sound waves have less space to travel. On the other hand, a large open room can lead to excessive echo unless it is treated properly with sound-absorbing materials. Additionally, furnishing materials like carpets, draperies and furniture can help to dampen reflections bounced off of hard surfaces like walls or floors.

The placement of microphones also affects how well they capture sound since they tend to be sensitive to direct sounds while also capturing any indirect reverberations in an echo-like fashion. In most cases, it pays to adjust their position slightly in order to eliminate any unnecessary noise. To further reduce echoes, some producers will use acoustic foam panels on walls and ceilings, which absorb more high-frequencies while letting bass frequencies pass through untouched making them ideal for better capturing subtle vocal nuances or harmonic sounds such as strings or brass instruments.

To accurately measure acoustical space and identify potential problems associated with recording in that specific location one should use specialized tools such as SPL meters (sound pressure level) or reverberation meters (RT60). This allows for optimal microphone setup before even pressing record thus resulting in much higher levels of clear audio for video production projects.

Microphone Placement

Microphone placement is one of the most important factors that influence sound quality. When positioning a microphone for recording, it’s important to consider the shape of the room, reflections and possible reverb or echoes. The closer a microphone is to the source, the more natural and lifelike its sound will be. Placing a mic close to the source will reduce interference from other sounds in the room.

In order to minimize reverberation, use absorptive materials such as curtains, foam panels, heavy carpets and mattresses around your mic. If you need to move your microphone away from your talent or move them within a scene, invest in a lavalier or shotgun/camera mountable microphone so that you can easily reposition it without affecting audio quality or phase coherence. To reduce background noise even further, use a windscreen or pop filter when recording outside.

When recording indoors with multiple people speaking at once, it is best to place multiple directional microphones around the talent rather than have one omnidirectional microphone which can pick up every sound indiscriminately. This allows for better separation between each speaker decreasing any unwanted bleed-through between mics and improving sound clarity for editing purposes later on. It’s also helpful to add an overhead mic which captures an ambient recording of everyone in our room that you can then blend with close-mic recordings while editing if needed.

Audio Processing

Audio processing is the application of digital signal processing to audio signals in order to make them sound better. Audio processing can involve sound synthesis, noise reduction, equalisers, and volume controls among other things. Some common audio processing techniques include filtering out background noise, increasing bass or treble tones, reducing the amount of low-frequency rumble and tackling any clipping issues.

The main goal of audio processing is to enhance the overall sound quality by improving the clarity and intelligibility of the audio signal while simultaneously reducing any unwanted noise that may interfere with understanding. Audio processing can also help make a synthesized sound more natural-sounding since artificial sounds don’t always translate well into a real-world situation. By manipulating audio signals in such a way that increases their clarity and fidelity, it makes it much easier for listeners to identify speech over distracting background noises and other sounds that can diminish its quality.

In video production settings, audio processors are incredibly useful in post-production tasks by enabling editors to quickly clean up problem areas in their recordings such as hums or background noises without needing to manually process each element individually. This saves time as well as energy since editor don’t have to worry about dealing with complex settings and mixing boards anymore — all they need is a good understanding of how their desired parameters will translate into the final output. If you want pristine sound for your videos then investing in an effective audio processor can save you a lot hassle and improve your productions overall quality!

Techniques to Improve Sound Quality

Sound quality is an important factor in video production, as good audio can make a video much more impactful. With the right techniques and equipment, you can significantly improve the sound quality of your video. In this article, we will discuss some of the techniques that you can use to ensure high-quality audio in your videos.

Use High-Quality Audio Equipment

In the world of video production, sound quality is the measure of how accurately recorded and processed sound components can be heard. Poor sound quality can result in distorted audio that is muffled, too quiet, or too loud. There are a few important steps to improving the sound quality of a video production.

One of the most important steps is to use high-quality audio equipment. High-quality audio gear will add clarity and overall presence to your sounds while also providing more precise control over levels and better noise reduction capabilities. Investing in good microphones, preamplifiers, digital mixers, processors and other gear is key to achieving high-quality sound. It’s worth noting that cheaper gear may be adequate when recording speech or simple background sounds but higher quality gear should be used for complex music recordings and for acceptable broadcast-level output on professional projects such as films or television shows.

Another important step towards improving your sound quality is to invest in proper acoustics for your recording environment – this includes adding treatment panels to absorb excessive reverberations from walls or other objects in your space as well as using acoustic baffles strategically placed around microphones for accurate directional frequency response properties. By minimizing reflections in your space you are helping ensure clear and precise recordings without unnecessary interference from echo or excessive reverberation.

Use Room Acoustic Treatment

Proper room acoustic treatment can help to improve the sound quality of any video production. Starting with the right-sized room for your sound needs, the next step is to consider acoustic treatments such as wall panels, bass traps and diffusers. Wall panels can absorb low frequency sound waves and reduce reverberation time, allowing more accurate listening. Bass traps help contain low frequencies in corners and create a flatter frequency response across the vocal range. Diffusers are scattered throughout the room, enabling sound energy to be released more evenly in all directions at multiple frequencies, reducing early reflection and random noise in the environment for cleaner sounding audio recordings. For best results, an acoustician can be hired to evaluate a space for optimal acoustic design and provide specialties related to absorbing and diffusion of sound waves in specific parts of the production studio or work space.

Use Audio Processing

Using an audio processor is one of the most effective techniques to improve sound quality. Audio processors are devices that allow you to take an audio signal and alter it in some way such as EQ, compression, limiting and more. Depending on your particular sound quality needs, there are a variety of different types of processors available.

For example, a compressor limits audio levels so that sounds which are too loud or soft will be leveled out so they don’t become distorted or inaudible during playback. It also helps to reduce background noise. EQ allows you to adjust the mix of different frequencies within a track for more precise control over the frequency balance of your sound. You can also use reverbs and delays to create ambiance and depth within your recording.

Audio processors can help you enhance the quality of any sound you record and give you greater control over how it sounds in the end product. Whether it’s creating rich vocal tones with reverb/delay or tightening up mixes with appropriate level adjustment tools, this tool can help you transform your sound into something truly remarkable!


In conclusion, sound quality is a vital part of successful video production. Even superbly shot footage can be ruined if the sound is not up to par. Fortunately, there are techniques that can keep audio from sounding hollow and flat, as well as devices that will make your sound match the level and clarity of the visuals.

Using high-quality microphones for capturing dialogue, capturing sound from multiple sources, raising the ambient noise levels of quieter scenes and using limiters to prevent distortions can all help maintain good quality audio in your video production. No matter what type of video you’re creating, focusing on improving your audio recording technique can pay off in higher customer satisfaction with your finished product.
