Subtractive EQ removes certain frequency ranges from a sound while additive EQ adds them. Subtractive EQ reduces resonance and eliminates unwanted noise, while additive EQ enhances certain aspects of the sound.
Equalization, or simply EQ, is a fundamental tool in the audio industry, as it allows engineers to manipulate the frequency content of a sound. However, there are two basic types of EQ: the additive EQ and the subtractive EQ. The former aims to increase the volume of certain frequency ranges, while the latter decreases it.
They both have their uses and advantages, depending on the needs of the mix. Subtractive EQ is often used to remove unwanted noise or resonance or to give more space to other instruments in the mix. On the other hand, additive EQ is used for enhancing harmonic content or boosting the presence of an instrument in the mix. We will delve deeper into the differences between subtractive and additive EQ and when to use each one.

Subtractive Vs Additive Comparisons
Subtractive and additive comparisons are two different methods used to compare audio equalizers. Additive EQ boosts specific frequencies to enhance sound quality, while subtractive EQ reduces frequencies to minimize unwanted sounds. Both methods have their own benefits and should be used depending on the specific needs of the audio recording.
As a sound engineer or music producer, you can use equalizers (EQ) to make your mixes sound better. EQ is a tool that can boost or cut different frequency ranges to enhance or reduce specific elements of a mix. EQs are divided into two categories: subtractive and additive EQ. In this article, we will compare the two categories and highlight their differences.
Subtractive Eq
Subtractive EQ involves cutting specific frequency ranges to remove unwanted sounds and form a balance in the mix. With this type of EQ, you can remove harsh or muddy frequencies that clash with other instruments or vocals. Subtractive EQ can clean up the mix and make other elements sound more defined and clear. However, it requires a trained ear to identify the problem frequencies and cut them without causing damage to the overall mix.
Additive Eq
Additive EQ involves boosting specific frequency ranges to enhance sounds and bring elements forward in the mix. With this type of EQ, you can increase the presence of vocals, add depth to instruments, and make the mix sound more colorful. Additive EQ can add energy and excitement to a mix, but it requires a careful approach not to introduce harsh or undesired sounds.
Subtractive Vs Additive Eq: Which One To Use?
Subtractive EQ is suitable for solving specific problems in a mix. It comes in handy when you need to remove unpleasant sounds that affect the overall quality of the mix. Additive EQ is for shaping sounds and bringing out particular elements in the mix. It works best for adding clarity, warmth, and depth to sounds. In conclusion, understanding the difference between subtractive and additive EQ is essential for producing the best mixes. Both types of EQ are useful, and it’s up to the sound engineer to determine which one to use depending on the problem or the desired effect. Remember to always trust your ears and make informed decisions when using EQ.

Understanding Subtractive Eq
Understanding subtractive EQ involves removing unwanted frequencies from an audio signal using a process known as EQ. Compared to additive EQ, subtractive EQ has a more natural effect on the overall sound quality and is commonly used in music production and sound engineering.
Understanding Subtractive EQ Subtractive EQ and additive EQ are two essential concepts in audio production. As a beginner, anyone can get confused about the difference between them. In this article, we will discuss the Subtract EQ and its working process in detail. What is Subtractive EQ? The subtractive EQ process involves reducing the frequency content from a specific audio signal by cutting down some frequency ranges. Generally, a sound signal contains unwanted background noise or hum, which will interfere with the overall sound quality. Subtractive EQ is an extremely useful tool for removing the unwanted sound, such as background noise, hums, hisses, and pops. How Subtractive EQ Works Subtractive EQ is done by using an EQ plugin. This plugin divides the audio spectrum into frequency bands and allows to increase or decrease the levels of those bands. When using subtractive EQ, the user needs to reduce the audio frequency range instead of boosting it. This can be done by selecting the particular audio frequency range with the equalizer, usually by applying a high-pass or low-pass filter on it. It can remove the unnecessary noise or hum, making the final sound clearer and more defined. In summary, Subtractive EQ is an essential tool for removing unwanted sound from audio production. By controlling the frequency ranges, a user can eliminate unwanted background noise that can be useful in the final mix of the production.
Understanding Additive Eq
Additive EQ involves boosting frequencies, rather than cutting them like subtractive EQ. Understanding additive EQ is essential for achieving a balanced and dynamic mix, allowing you to enhance specific frequencies in your audio without negatively affecting other elements.
What Is Additive Eq
Additive EQ is a type of equalization used in audio processing that involves boosting certain frequency ranges in a sound signal. When certain frequencies are boosted, it can enhance the clarity and definition of a sound and make it more present in the mix.
How Additive Eq Works
Additive EQ works by boosting specific frequency ranges that lack presence in a sound signal. By accentuating these specific frequencies, it can increase the overall tonal balance of the sound and make it sound more natural. Additive EQ can be applied to individual tracks or used in the mixing stage to enhance the overall mix. One approach to using additive EQ is to consider the sound’s spectral balance and identify which frequencies are lacking and what needs to be boosted. For example, if the high frequencies in a vocal recording sound dull, you might boost the higher frequency range to enhance the clarity of the vocal. It’s important to note that while additive EQ can be used to boost certain frequencies, too much boosting can create unwanted resonance or frequency buildup, resulting in a harsh or unnatural sound. When using additive EQ, it’s essential to listen carefully and make subtle adjustments to achieve the desired effect.
Examples Of Additive Eq
Here are a few examples of when additive EQ might be useful:
- Enhancing the clarity of a vocal by boosting the high-frequency range
- Emphasizing the presence of a guitar solo by boosting the upper mid-frequency range
- Adding brightness to a piano recording by boosting the high-frequency range
In conclusion, additive EQ is a useful tool that can enhance a sound signal by boosting specific frequency ranges. When used correctly and in moderation, it can improve a sound’s tonal balance and overall presence in the mix.
When To Use Subtractive Eq
Subtractive EQ is a powerful tool that audio engineers use to shape the sound of individual tracks and entire mixes. It is effective in removing unwanted frequencies, correcting tonal imbalances and creating space in the mix.
Eliminating Unwanted Frequencies
Unwanted frequencies can make the mix sound muddy and cluttered, which can cause the individual tracks to lose definition. Subtractive EQ is useful in removing those frequencies that are not contributing to the overall sound of the mix. By identifying and removing these frequencies, you can create a cleaner, more focused mix.
For example, if a bass guitar and a kick drum are both occupying the same frequency range, they will clash with each other, causing the mix to sound cluttered and indistinct. Using a subtractive EQ, you can reduce the lower frequencies of the bass guitar and allow the kick drum to occupy that frequency range, resulting in a clearer and more defined mix.
Creating Space In The Mix
Subtractive EQ is also useful in creating space in the mix. By cutting frequencies that are not essential to a particular track, you can create more room in the frequency spectrum for other instruments to occupy. This can result in a more balanced and spacious mix.
For example, let’s say you have a mix that consists of a guitar, bass guitar, drums and vocals. The guitar and vocals are occupying the same frequency range, which is causing the mix to sound cluttered. By using subtractive EQ on the guitar track and removing some of the frequencies that are clashing with the vocals, you can create more space in the mix for both the guitar and vocals to cut through.
In Conclusion
Subtractive EQ is a powerful tool that can be used to great effect in creating a more focused and balanced mix. By using it to eliminate unwanted frequencies and create space in the mix, you can create a more polished and professional-sounding final product.
When To Use Additive Eq
One of the most useful techniques an audio engineer has at their disposal for adjusting the sound of a track is the equalizer. EQ can be applied in two ways – additive or subtractive. Additive EQ involves boosting frequencies to enhance the mix, while subtractive EQ involves cutting frequencies to remove unwanted sounds.
Boosting Desired Frequencies
The first reason to use additive EQ is when you want to boost specific frequencies in a track. Boosting allows you to make certain elements of the mix stand out, giving them more prominence. This technique is often used to make vocals more audible in a dense mix, or to add brightness to a guitar riff. However, boosting should be used cautiously, as it can also introduce unwanted noise and make tracks sound harsh or unnatural.
Enhancing The Mix
Another reason to use additive EQ is when you want to enhance the overall mix. By boosting selected frequencies in individual tracks, you can make them gel together more cohesively. This technique is useful when you have a mix that sounds a bit muddy or lacks clarity. By adding brightness or clarity in certain frequency ranges, you can create more separation between parts and add depth and clarity to the mix.
However, it’s important to note that additive EQ should be used sparingly. Overuse can lead to a mix that is overly bright or cluttered. As with all EQ techniques and mixing in general, it’s important to use your ears and trust your instincts.
In conclusion, additive EQ is a powerful tool for enhancing the sound of your tracks. By boosting specific frequencies, you can make instruments and vocals stand out more prominently or enhance the mix to create a more cohesive sound. However, it must be used sparingly to avoid introducing unwanted noise and creating an unnatural sound.
