Most people think of filters as something that only removes frequencies from an audio track. But what if you want to do the opposite? What if you want to boost or emphasize certain frequencies in a track? That’s where high pass filters come in aswell. High pass filters are an essential part of mixing, especially when it comes to vocals or instruments that need to stand out. Let’s take a deeper look at what they are and how they can make your tracks sound better!
In this guide, we'll explain what high pass filters are and why you need to use them.
A high-pass filter (HPF) is a signal processing device that removes low frequencies from a signal. In effect, they can be used to remove unwanted bass and high-frequency noise from your audio recordings.
High pass filters are also known as low-cut filters because they create a steep roll off around the cutoff frequency (the point at which the gain or amplitude is reduced by 3dB). This means you can use them to remove unwanted low frequencies and improve clarity in your recordings. Some types of HPFs provide adjustable knobs for setting this cutoff frequency, while others have fixed values set by the manufacturer.
High pass filters are most commonly used in music production and sound engineering applications where you want to cut out muddy bass frequencies so you can hear everything else clearly. For example: if you were recording an acoustic guitar track through an amp with built-in reverb effects, chances are there would be lots of low end coming through that could muddy up the sound—but inserting an HPF after the amp will help get rid of those muddy lows without affecting much higher frequencies like cymbals or vocals (which tend not get mixed down too far anyway).
What is a high-pass filter?
A high-pass filter is a type of filter that cuts low frequencies. They're often used to remove unwanted noise and rumble, but they can also be useful in music production.
Putting the high-pass filter into practice
A high-pass filter is a tool that removes low frequencies from your audio. If you're recording a track, it can help you reduce the rumble of the room to clean up your recording. Or, if you're mixing down a song, it can let you remove bass frequencies to make way for other instruments in your mix.
There are plenty of ways to use this effect:
To remove low frequency noise from an audio file: You can apply a high-pass filter on an entire clip or on part of it by drawing in selection points. The resulting sound will be higher pitched and have less bass than before; cut out any unwanted parts like background noise or hissing sounds with this tool!
To reduce rumble when recording vocals: Use a steep cutoff point for removing hums and other unwanted sounds from around the mic during vocal recordings—this will leave only what's best about the performance (the singer's voice) intact when all else has been filtered out! This technique works well when combined with compression too so both processes share similar goals but accomplish them differently — try them together sometime!
How to set a high-pass filter in your DAW
First, make sure that you have the high-pass filter on your track (you can do this by right clicking the track header and selecting "add effect").
Now, go over to your DAW's filter window. You should see two parameters: cutoff frequency and resonance. Set these values to whatever you want for your sound. For my example I'm going to use 100Hz for cutoff frequency and 0% for resonance.
Finally, make sure that you play back your song or audio clip!
When should I use High-Pass Filters?
Removing rumble and hiss from your recordings.
Cleaning up your mix by removing unused frequencies.
High pass filters are an essential tool for mixing audio.
High-pass filters are an essential tool for mixing audio, and can be used in many different ways to shape the sound of your mix. If you're new to mixing music, a high pass filter may seem like just another knob or button on your mixer—but it's actually more than that. It's a tool that allows you to sculpt the frequency balance of your tracks so they sit harmoniously together in the final mix.
High Pass Filter Basics
A high pass filter (HPF) is a device which removes all frequencies below its cutoff point from an audio signal—in other words, it lets through only those parts of the signal above this point.
Conclusion
Now that you have a good idea of what a high-pass filter is, the next time you have a muddy sounding mix or want to make something stand out, you'll be able to make the needed changes and experiment with your sound.

Summary
All in all, high-pass filters are an essential tool for mixing audio. They can be used to remove unwanted low frequencies or boost certain parts of your sound. But it’s important not just to know what they do, but also when and where they should be used. If you think about using them as you work through this guide, then hopefully we’ve given you enough information to get started with some great new techniques!
