When it comes to mixing and producing music, one of the most recurring debates among audio engineers and producers is whether or not to high pass sub bass. While some argue that high passing sub bass frequencies can clean up the low end and create more clarity in the mix, others claim that it can compromise the power and impact of the sub bass. In this article, we will explore the pros and cons of high passing sub bass, helping you make an informed decision in your own music production endeavors.
Understanding The Sub Bass Frequency Range
Sub bass frequencies, typically ranging from 20Hz to 60Hz, are the lowest frequencies in the audio spectrum. These frequencies are felt more than heard, creating the powerful and rumbling sensations in music, particularly in genres like hip hop, EDM, and dubstep. Understanding the sub bass frequency range is crucial for audio mixing engineers to make informed decisions when high passing sub bass.
When producers or mixing engineers talk about sub bass, they are referring to the lower end of the low-frequency range, typically below 60Hz. This region is responsible for adding depth, richness, and weight to the low end of a mix. However, it is important to note that sub bass should not be confused with bass, which generally spans from 60Hz to 250Hz.
By having a clear understanding of the sub bass frequency range, mixing engineers can better address issues related to low-frequency elements in a mix and make informed decisions when it comes to applying high pass filters or other techniques to control the sub bass frequencies.
The Purpose Of High Passing In Audio Mixing
High passing is an audio mixing technique employed to eliminate unwanted low-frequency information, such as rumble or unnecessary subsonic content, from a sound source. By applying a high-pass filter, frequencies below a certain cutoff point are attenuated, allowing for more control over the mix’s low-end energy.
The primary purpose of high passing is to create sonic clarity and definition by removing unnecessary low-frequency content that can potentially cloud the mix. Rumble and subsonic elements are commonly found in recordings, which can add unwanted mud or muddiness to the overall sound. High-pass filtering ensures that only the essential low frequencies are present, resulting in a cleaner and more focused mix.
Additionally, high passing assists in creating balance within the mix. By reducing the low frequencies in certain elements, such as non-bass instruments or vocals, the focus can be shifted to the dedicated bass elements, ensuring they have enough space to shine. This helps to generate a better sense of separation between different instruments and allows the listener to perceive each element more clearly.
Ultimately, high passing is a powerful tool in audio mixing, providing control and enhancing the overall quality of a mix by removing unnecessary low-frequency content and improving balance and clarity.
Pros Of High Passing Sub Bass Frequencies
High passing sub bass frequencies can offer several advantages in audio mixing.
Firstly, high passing allows for greater headroom in the mix. By removing the lowest frequencies that may not be audible or necessary, it frees up space in the low end, allowing other elements in the mix to be more prominent and defined. This can prevent muddiness and improve overall clarity.
Secondly, high passing can help to manage the relationship between the kick drum and the bass. By removing excessive low-end content from the bass, it creates a cleaner separation between the two elements, making each more defined and allowing them to complement each other without clashing.
Additionally, high passing can help in preventing potential issues with playback systems that may struggle to reproduce ultra-low frequencies accurately. This is particularly relevant for smaller speakers or headphones, where sub bass frequencies may cause distortion or unwanted vibrations.
In summary, high passing sub bass frequencies can enhance the overall mix balance, improve clarity, and ensure compatibility across different playback systems. However, it is important to use this technique judiciously to avoid compromising the integrity and impact of the low-end foundation.
Cons Of High Passing Sub Bass Frequencies
High passing sub bass frequencies, while commonly used in audio mixing, have their drawbacks as well. It is important to consider these cons before implementing high pass filtering on your sub bass:
1. Loss of Power and Impact: The sub bass frequencies often provide the punch and power to a mix, particularly in genres like hip-hop, EDM, and dubstep. High passing these frequencies can result in a loss of that low-end impact, making the mix sound weaker and less energetic.
2. Possible Phase Issues: When applying a high pass filter, phase shifts occur at the cutoff frequency. This can introduce phase cancellation issues when combined with other elements in the mix, leading to a muddier and less defined low-end.
3. Limitations on Speaker Systems: High passing sub bass frequencies may not translate well across different playback systems. Some consumer-grade speakers or headphones might struggle to reproduce low frequencies accurately, resulting in an imbalance and the perception of missing bass in the mix.
4. Reduced Harmonic Content: Sub bass frequencies often carry important harmonic information that contributes to the overall tonal balance of a mix. By removing these frequencies, the harmonics can be diminished, leading to a less full-bodied and less rich sounding mix.
While high passing sub bass frequencies can solve certain issues in a mix, it is crucial to weigh these cons against the benefits before making a decision. Being aware of the potential drawbacks will help you make informed choices to achieve the desired sonic balance and impact in your mixes.
Impact On Sound Quality: High Passing Vs. Keeping Sub Bass
High-passing sub bass frequencies can have a significant impact on the overall sound quality of a mix. By using a high-pass filter, you are essentially removing frequencies below a certain cutoff point. While this can help clean up the low end and make room for other elements in the mix, it can also affect the perceived impact and depth of the sub bass.
When applying a high-pass filter, it’s important to consider the genre and style of the music. In some genres like EDM or hip-hop, where a powerful and punchy sub bass is crucial, removing too much of the lower frequencies can result in a weak and thin sound. On the other hand, genres like rock or acoustic music may benefit from a cleaner, more focused low end achieved through high-passing.
Finding the right balance is key. Sometimes, instead of completely high-passing the sub bass, it may be more effective to use gentle filtering or EQ adjustments to shape the sound while retaining the fundamental frequencies. Experimentation and careful listening are essential in determining the ideal approach for each specific mix and musical context.

Managing Clarity and Definition in the Mix: High Passing Sub Bass
One of the main benefits of high-passing sub-bass frequencies in audio mixing is the enhanced clarity and definition it brings to the overall mix. Sub-bass frequencies can sometimes cause muddiness and mask other elements in the mix, resulting in a loss of detail and a less defined sound.
By applying a high-pass filter to the sub-bass frequencies, you can remove unnecessary low-end rumble and create more space in the mix for other elements to shine. This can help each instrument and element in the mix to be perceived more clearly and distinctly.
However, it is essential to find the right balance when high-passing sub-bass frequencies. Overdoing it can lead to a thin and weak sound, losing the power and impact that sub-bass frequencies bring to a track.
Therefore, careful consideration should be given to the specific characteristics of the mix and the desired sound before applying a high-pass filter to sub-bass frequencies. Experimentation and critical listening are crucial in finding the suitable cutoff point for achieving clarity and definition without compromising the overall balance and impact of the low-end.
Maintaining Low-End Balance: High Passing Techniques
When it comes to mixing audio, maintaining a balanced low-end is crucial. One technique that can help achieve this balance is high passing the sub bass frequencies. High passing refers to the process of cutting out unwanted low frequencies below a certain point, allowing for better control and definition in the mix.
By applying a high pass filter to the sub bass, you can remove any unnecessary rumble or mud that may be present in the lower frequencies. This can help create more space in the mix for other elements to shine through and ensure that the sub bass doesn’t overpower the entire track.
However, it is essential to exercise caution when implementing high passing techniques. Overdoing it can result in a thin or weak low end, compromising the overall impact and energy of the track. Therefore, it’s crucial to strike a balance and find the sweet spot where the sub bass remains prominent but doesn’t overshadow the rest of the mix.
Using high passing techniques to maintain low-end balance can be particularly beneficial in genres like EDM, hip-hop, or pop, where a tight and controlled low end is desired. Experimentation and careful listening are key to finding the right amount of high passing that works best for your mix.
