The Loudness War in 2022: 70 Years of Audio Confusion
It was the late 1950s, and people were starting to take notice of something strange happening in the world of music. Record companies were starting to compete with each other to make their records louder and louder. This phenomenon became known as the Loudness War. In this blog post, we will explore the history of the Loudness War, and why they are such a big issue in the world of audio engineering.
Anyone who has ever mixed a song knows that the most important tool is the human ear. However, the ear can be easily fooled, which is why it is essential to have a reliable reference metering system.
This system can help to ensure that the final mix is compliant with the various parameters for the various media streaming platforms that are available today. In addition, this system can help to prevent clipping and other audio issues that can impact the quality of the final mix. While there are many different metering systems on the market today, it is important to choose one that is durable and easy to use.
With so many options to choose from, it can be difficult to know where to start. However, by taking the time to research the different options, you can be sure to find a system that will meet your needs and help you produce the best possible mix.
The Loudness War
The Loudness War have their roots in the 1950s, when people started to notice that records were getting louder and louder. This was due to a competition between record companies to make their records sound louder than their competitors. This was because people tended to play the louder records in jukeboxes more often. This led to an arms race of sorts, with companies constantly trying to one-up each other in the loudness department.
This arms race continued into the 1960s and 1970s, with companies using ever-more sophisticated methods to make their records sound louder. This often led to music sounding distorted and unpleasant, as the waveforms of the sounds were being artificially clipped in order to make them louder.
There’s a physical limit to how loud a vinyl record can be cut without making it unplayable, so even the loudest-cut records managed to retain quite reasonable dynamics.
The advent of the compact disc in the 1980s allowed for even greater levels of volume, as well as Extended Playtimes that were sometimes twice as long as those on vinyl. But there are drawbacks to this increased Loudness War volume levels.
First, the overall level of noise in society has increased, which can lead to hearing damage. Second, the increase in loudness has resulted in a decrease in the dynamic range of music, which can make it sound less natural and more fatiguing. Third, the increase in loudness has made it more difficult for music to compete with other noise sources in our lives, such as traffic or conversation. As a result, we may find ourselves turning down the volume of our music, which defeats the purpose of listening to it in the first place.
In the 1980s, digital audio became more common, and this allowed for even more Loudness War-style shenanigans. With digital audio, it is possible to make a recording sound as loud as you want without any distortion. This led to many records being mastered at extremely high levels, which often made them sound bad.
The Loudness War are still going on today, and they show no signs of stopping. With the advent of streaming services like Spotify, there is now more pressure than ever to make records sound as loud as possible. This is because these services use what is known as a “loudness normalization” algorithm, which levels out the loudness of all tracks so that they are all at the same volume. This means that if your track is not as loud as the others, it will sound quieter and less impactful.
So why do the Loudness War continue to this day? There are a few reasons.
First of all, there is a lot of pressure on artists and record labels to make their music sound as loud as possible. This is because people tend to prefer music that is louder and because streaming services use loudness normalization.
Secondly, it can be very difficult to make a record sound both loud and good. Often, the two are mutually exclusive.
Finally, there is a lot of misinformation out there about how to make a record sound good. Many people believe that the only way to make a record sound good is to make it as loud as possible when in reality, this is often not the case.
The Loudness War is a big problem in the world of audio engineering, and they show no signs of stopping anytime soon. Hopefully, with more education and awareness, we can start to move away from the loudness race and towards a more balanced approach to audio mastering.
Loudness Management
Imagine you’re settling in for a movie night. You’ve got your favorite snacks and drinks, you’re cozy on the couch, and you’ve finally found the perfect film. The only thing left to do is press play…and then scramble to find the remote when the opening credits blast out of your speakers at an ear-splitting volume. We’ve all been there, and it’s one of the most frustrating things about watching TV.
Thankfully, there’s a solution: loudness management. Loudness management is the process of playing all programs at a consistent loudness, relative to each other. That way, once you set your volume to a comfortable level, you should never have to change it, even as you switch from a movie to a documentary, to a live concert.
For example, Netflix specifically aims to play all dialogue at the same level, so you can always understand what’s being said without having to adjust the volume. As a result, loudness management ensures that you can sit back, relax, and enjoy your favorite films and TV shows without any unwanted interruptions.
Netflix is constantly working to ensure that its content is of the highest quality. Part of this involves ensuring that all dialogue is easy to hear and understand. To do this, they measure the loudness of all content before encoding it.
This helps them to adjust the level of each piece of dialogue so that it is audible without being disruptive. The use of anchor-based measurement ensures that all dialogue is consistent, regardless of the type of show or movie.
This allows viewers to focus on the story, rather than trying to decipher what is being said. As a result, Netflix’s commitment to quality audio helps to create a more enjoyable viewing experience for their customers.
Dynamic Range Control
The goal of dynamic range control is to optimize the dynamic range of a program to provide the best listening experience on any device, in any environment. Dynamic range is the difference between the loudest and softest sounds that a system can reproduce. It is often measured in decibels (dB). Most humans can hear a sound with a dynamic range of about 140 dB. older systems had a limited dynamic range, often around 40 dB.
This meant that very quiet sounds were lost, and very loud sounds were distorted. Newer systems have a much greater dynamic range, often greater than 90 dB. This means that very quiet sounds can be reproduced without distortion, and very loud sounds can be reproduced without clipping.
Dynamic range control adjusts the levels of all sounds so that they are within the system’s dynamic range. It makes sure that very quiet sounds are audible, and very loud sounds are not distorted. It also adjusts the levels of all sounds so that they are evenly balanced. This provides the best listening experience on any device, in any environment.
One of the challenges of modern television is that the dynamic range of many programs often exceeds the dynamic range of the viewer’s device and environment. This can lead to a number of problems, including the need to constantly adjust the volume and difficulty understanding dialogue.
In these cases, dynamic range compression (DRC) can be used to reduce the dynamic range of the content to a more manageable level. While DRC does have some drawbacks, such as reducing the overall loudness of the soundtrack, it can be a useful tool for ensuring that viewers are able to hear all of the details in a program’s audio.
When you’re watching a movie on Netflix, the goal is to provide you with the best possible experience. Part of that experience is delivering the audio in a way that sounds great, regardless of what device you’re using.
To do that, Netflix employs a sophisticated algorithm that reduces dynamic range in a sonically pleasing way. This ensures that dialogue levels remain unchanged, and only a gentle adjustment is made when sounds are excessively loud or soft for the listening conditions. As a result, you can be confident that you’re getting the best possible sound quality when watching your favorite movies and TV shows on Netflix.
All-Analogue Times
In the all-analog time, mixing consoles, tape machines, vinyl discs, and other consumer replay media all employed a nominal ‘reference level’ — essentially the average program signal level. Above this reference level, an unmetered space called ‘headroom’ was able to accommodate musical peaks without clipping.
This arrangement allowed different materials to be recorded and played with similar average loudness levels, whilst retaining the ability to accommodate musical dynamics too. The result was a more natural and musically satisfying sound that gave listeners a sense of space and air around the instruments. In the digital age, however, things are very different.
With digital audio, it is all too easy to add gain until the converter clips, resulting in a harsh, distorted sound. Moreover, many modern recordings are deliberately compressed and limited to maximize loudness at the expense of dynamics. While this may make them sound impressive at first, prolonged listening quickly becomes fatiguing.
Thankfully, there are still a few recording engineers who understand the value of headroom and dynamic range, and who are able to produce recordings that have all the power and punch of digital audio without sacrificing musicality. These recordings are a joy to listen to and provide a welcome respite from the relentless barrage of sonic
Moving to Digital Producing & Mixing
From the perspective of sound quality, digital audio always had one big advantage over analog – it was (and is) immune to interference from electrical and magnetic fields. This meant that in theory at least, digital audio systems could offer much higher levels of performance than their analog counterparts.
However, in practice, early digital audio systems were often found wanting. One major problem was that the converters used to convert the analog signal into digital form were not as good as they should have been. This meant that the signal levels had to be kept relatively low in order to avoid distortion. As a result, the ‘reference level’ effectively became the clipping level, and the notion of headroom fell by the wayside, becoming this war’s first casualty!
Considerations When Mixing In Big Rooms
There are a few things to consider when choosing a monitor setup for a recording studio. One is the type of layout, either ITU or cinema. The ITU layout is typically used in smaller studios and more closely reflects what the consumer’s system will be like.
This can be important for things like panning movements, as the imaging will be different between the two layouts. Another thing to consider is the size of the room and the number of speakers needed. For smaller rooms, near-field monitors may be sufficient, but for larger rooms, floor-standing speakers may be necessary in order to get the full range of sound.
Finally, it is also important to think about budget when choosing monitors, as there can be a wide range in prices. Ultimately, there are a lot of factors to consider when choosing monitors for a recording studio, but with a little research, it is possible to find the perfect setup for any situation.
Since mixes should be monitored through a near-field system, it is important to also consider other ways to check for intelligibility. One way to do this is by having something that mimics a TV speaker.
This can be very useful in checking for clarity and understanding. However, it is important to note that there is no one-size-fits-all solution. What works for one mix may not work for another. I still remember when I watch (or listened) to a new mix on youtube on my TV, and it was not good. It did sound great on my iMac so.
As such, it is important to experiment and find what works best for you. But ultimately, by monitoring your mixes through a near-field system and also considering other options, you can ensure that your mixes are intelligible and sound their best.
Authenticity – Acceptable Or Harmful
In filmmaking, the sound is often one of the most overlooked aspects. However, it can be just as important as visual elements in setting the tone and creating an immersive experience. This is why many filmmakers choose to use sound design to enhance their films. Sound design is the process of creating or selecting sounds that are used in a film. These sounds can be anything from dialogue and music to Foley effects and ambiance.
By carefully crafting the soundscape of a film, filmmakers can control the emotional impact of their story and create a more realistic or otherworldly atmosphere. Of course, restricting the dynamics of sound can be essential in order to achieve the desired effect.
Realism is not always possible, and sometimes a more abstract or otherworldly approach is necessary in order to capture the essence of a story. Ultimately, it is up to each individual filmmaker to decide how best to use sound in their own films.
TV shows are often mixed with natural dynamics in the dialog, which can make it harder to hear and understand. How you choose to reduce the dialog dynamic range is up to you. One option is to lower the overall volume of the TV show. This will help to keep the dialog from becoming overwhelming. Another option is to use a soundbar or other audio device to help balance the sound.
By careful placement of these devices, you can help keep the dialog clear and easy to understand. Whichever option you choose, be sure to test it out before watching your favorite TV show. Otherwise, you may constantly adjust the volume and miss out on key parts of the story.
I believe that mixing TV drama is an essential part of the creative process. By mixing different elements of the show, such as dialog, music, and sound effects, the creative team can craft a unique and engaging experience for viewers.
By carefully balancing these elements, the team can create a soundtrack that amplifies the emotion of the scene and helps to draw viewers into the story. In addition, mixing allows the team to control the pacing of the show, ensuring that viewers are not left feeling confused or overwhelmed.
Ultimately, mixing is an essential tool for creating a successful TV drama. Without it, the creative vision of the team would be lost in translation.
The Broadcaster
The word broadcaster is most commonly used to refer to television and radio companies that transmit programs through the airwaves. However, in the age of streaming services, the term has taken on a new meaning.
Broadcasters like Netflix and Amazon Prime don’t have any transmitters, but they are effective ‘the one’ delivering to ‘the many’ in the standard definition of a broadcaster.
Unlike traditional broadcasters, they are not regulated by governments and they are not beholden to advertisers. This allows them to take risks and innovate in a way that traditional broadcasters cannot. As a result, they have changed the landscape of television and film, and they are redefining what it means to be a broadcaster.
As we all know, there’s nothing worse than getting settled in for a good show only to have to scramble for the remote when the volume gets too loud. Or worse, having to constantly adjust the volume because it keeps fluctuating.
Netflix understands that the last thing you want is for your viewing experience to be interrupted, which is why they actively work to ensure that their content sounds great no matter what kind of environment you’re watching in.
So whether you’re curled up on the couch with your favorite blanket or out and about with your earbuds, you can rest assured that your show will sound just the way it should. And isn’t that the way it should be? After all, the best way to experience your favorite show is without any interruptions.
Netflix Loudness
As any audio engineer knows, one of the most important aspects of a good mix is dynamics. A well-crafted mix will have a wide range of loud and soft sounds, giving the listener an engaging and immersive experience.
Unfortunately, many streaming services compress audio mixes, resulting in a muddy and flat sound. This is not the case with Netflix. The company is committed to preserving the creative intent of its audio mixes, and as such, they do not compress or limit the dynamic range of their audio tracks.
This may result in some content sounding quieter than others, but it ultimately provides a better listening experience for customers. Netflix also normalizes all audio deliveries to ensure that all tracks play at the same level on service. This may cause some audio to be raised or lowered in the overall mix level, but it ensures consistent playback between titles.
As a result, Netflix is able to provide its customers with high-quality audio that sounds true to the original intent of the mix.
If you are delivering your mix or master to shows that are aired on Netflix the game has changed. There are several important audio quality prerequisites for mix facilities that must be met in order to produce high-quality audio content.
Important: For all titles, 5.1 audio is required and 2.0 is optional. In addition, mono audio is only acceptable if the program’s original source is mono and no stereo or 5.1 mix exists. Mono audio must be duplicated on channels 1 & 2 and delivered as 2-channel in order to be properly compatible with all devices. By following these simple guidelines, everyone can enjoy the highest quality audio experience possible.
First, the average loudness must be -27 LKFS +/- 2 LU dialog-gated. This ensures that the audio is at a consistent volume and is easy to understand. Additionally, peaks must not exceed -2db True Peak. This prevents any sudden, jarring sound effects from damaging the audio quality.
Finally, audio should be measured over the full program according to ITU-R BS.1770-1 guideline. This ensures that the audio is accurately reproduced and that there are no issues with dropouts or other audio artifacts. By meeting these prerequisites, mixed facilities can produce high-quality audio content that sounds great and is easy to understand.
Any audio recording that is going to be used in sync with picture must be recorded at the native project frame rate. This is to ensure that there is no lag or delay between the audio and the visuals.
All audio deliverables should therefore match the camera and picture post-production frame rate. In addition, all audio must be synced to the final IMF/Prores picture delivery. Alternate/Dubbed Language and Audio Description Mixes should not contain an additional leader. Printmasters, M&Es, and stems may include standard 8-second Academy leader and 2-pops. By following these guidelines, you can be sure that your audio will be in sync with the picture and will not cause any lag or delays.
The following loudness range (LRA) values will play best on the service:
- 5.1 program LRA between 4 and 18 LU
- 2.0 program LRA between 4 and 18 LU
- Dialog LRA of 10 LU or less
When near field 5.1 mixes measure at less than 15% dialog, program-gated measurement will be used instead (-24db LKFS +/- 2 LU – ITU BS 1770-3)
For LoRo fold downs or down mixes, ITU-R BS.775-1 – 5.1 to Stereo with LFE muted is the international standard.

What is true peak level?
True peak level is the highest amplitude of a signal, including any transients or peaks that may be present. True peak levels can exceed the nominal level (the “average” or “rms” level) of a signal, and as such, they are a more accurate measure of the loudness of a signal.
What is dithering?
Dithering is the process of adding noise to an audio signal in order to improve the quality of the sound. Dithering can help to reduce quantization noise, which is a form of distortion that can occur when digital audio signals are converted from one format to another.
What is headroom?
Headroom is the amount of space between the peak level of an audio signal and the point at which clipping (distortion) occurs. Headroom allows for transients (sudden changes in volume) in an audio signal without causing clipping.
What is analog-to-digital conversion?
Analog-to-digital conversion is the process of converting an analog signal (such as a vinyl record or tape) into a digital format (such as a CD or MP).
Why are loudness war still happening?
Even though the Loudness War has been going on for over 70 years, it’s still happening today. The reason for this is that people tend to like music that is louder than average. This preference for loudness can be traced back to the early days of radio, when people would turn up the volume in order to hear faint signals. Over time, this preference has become ingrained in our culture, and now many people expect music to be loud.
Which is louder LUFS or LUFS?
LUFS is louder than LUFS. While this is a reasonably precise method of measuring loudness, using LUFS as the standard loudness units is generally preferable since it considers the perceived loudness of music as well as the overall audio reading.
