Before a song makes onto your Spotify playlist, it is mastered to optimize playback across many devices. Audio engineers equalize the melodies, so the music sounds just fine in most scenarios. While not all playback systems are ideal, finding the best eq for bass can make your music shine.

Why should you EQ your music if a professional engineer has examined it already? Well, there are two main reasons why you’d want to equalize the music, and they’re mutually exclusive. First, EQ settings are found in everything from phones, home theater soundbars, and streaming platforms such as Spotify and more. Second, understanding how an EQ works and using it properly brings sound sculpting to your fingertips.

What is an EQ?

Before we dive into the gritty details, EQ is an abbreviation of equalization. It is the process of modifying the volume of various frequency bands within an acoustic signal. It locals recreating accurate audio to adjust different amplitudes to amplify the signals at equal frequency. 

As you dip into more advanced versions of recording equipment, you can control the output of a specific frequency range, letting you twist the sound from your device. 

There are two parts to an EQ: center frequency and bandwidth. The middle frequency might sound complex, but it’s just selecting the specific frequency you want to adjust.

The bandwidth refers to how restricted the selection is for the adjustments you aspire to make. For example, suppose you go into a car and see the bass, which looks like a small hill when you adjust it. But, if you require a specific frequency range, then having a higher Q will allow you to achieve it. Virtually, it is more akin to a spire than a hill. 

Can you create a custom EQ? 

There are two ways to change your sound when learning about EQ. To begin with, you manage the decided frequency louder by raising the amplitude of a specific range. However, on the flip side, you can also reduce the output range according to your parameters.

This is called boosting. If you think about it, you’re just improving the output of something you like to hear more of. You can also reduce the results of a specified frequency for something that you don’t want to hear more about. 

Generally, cutting is usually a better approach than boosting.

As a general rule of thumb, cutting is better than boosting. However, if you improve too much, you can integrate distortion, which defeats the objective of what we’re trying to achieve here.

In short, it’s better to reduce the frequencies that you want less of than amplifying the ones you want to hear more. If done accurately, this will give you a similar output within the specified range of the distortion threshold. 


Everything you hear- is essentially vibrations that we visualize as waves moving in different directions. For instance- the hip-hop groove you hear moves very slowly, while higher pitches like the chirp of a bird move swiftly. All of the sound you’ll ever hear sustains within the 20Hz to 20kHz zone, and thus the number will be broader than average EQ. 

Some software comes with built-in presets, which can be a helpful starting point when managing the EQ. EQ is pre-set for a reason and is generally made by professionals. In addition, some in-built applications like Voicemeter or Equalizer Apo let you do a hearing test beforehand to see which frequencies match the most to your ears.
