Mastering Your Sound: Installing and Configuring PulseAudio-Equalizer on Linux Mint 21

Linux Mint 21 is a popular operating system known for its customization options and versatility. PulseAudio is a widely used sound server that allows users to control audio levels and configurations on Linux.

PulseAudio-Equalizer is an advanced tool that can change the tone and frequency of audio output, making it a must-have for audiophiles and people who need fine-grained control over their sound settings. In this article, we’ll discuss how to install PulseAudio-Equalizer on Linux Mint 21, verify its installation, and configure it to suit your needs.

We’ll walk you through the necessary commands and show you how to modify a specific file to add lines of code that will enable the equalizer. Let’s get started.

Installing PulseAudio-Equalizer on Linux Mint 21

To install PulseAudio-Equalizer on Linux Mint 21, open the terminal and enter the following command:


sudo apt install



This command tells the system to download the latest version of the PulseAudio-Equalizer and install it on your system. Once the installation is complete, you can verify it by using the version command, which displays the current version of the application.

To check the version of your PulseAudio-Equalizer, open the terminal and type:


pulseaudio-equalizer –version


Upon running this command, you’ll see the version of the installed equalizer in the terminal. If it displays the version number, it means your installation was successful.

Configuring PulseAudio-Equalizer on Linux Mint 21

After you have installed the PulseAudio-Equalizer on your system, you need to configure it to function correctly and efficiently. To do this, you need to add specific lines of code to a system file.

Go to your home folder and look for a file named “.config/pulse/” This file is responsible for defining the default PulseAudio configuration. To edit the file and add the necessary lines of code, open the terminal and type:


nano ~/.config/pulse/


This command opens the file in the nano text editor.

Scroll down to the end of the file and add the following line:


load-module module-equalizer-sink


This line of code instructs PulseAudio to load the equalizer as an audio sink, and it will be visible in the audio preferences window. After adding this line, save the changes made to the file by pressing “Ctrl+X,” followed by “Y” and hitting “Enter.”

Once you’ve saved the changes, you must restart the PulseAudio server.

To do this, enter the following command into the terminal:


pulseaudio -k && pulseaudio –start


This command kills the current pulse audio and restarts it with the new configuration added. Your equalizer is now up and running!


In this article, we have seen how to install and configure PulseAudio-Equalizer on Linux Mint 21.

The installation process requires a straightforward command, and verifying it is done using the version command. Configuring the equalizer involves adding a line to the file, which instructs PulseAudio to load the equalizer as an audio sink.

Finally, a command that restarts pulse audio must be used to apply the new configuration. With PulseAudio-Equalizer on your system, you can enjoy a more customized and high-quality sound experience.

These simple steps will provide you with a tool to fine-tune the sound output to your desired settings. So, go ahead and enjoy the music!

Using PulseAudio-Equalizer on Linux Mint 21

Now that you have installed and configured PulseAudio-Equalizer on your Linux Mint 21 system, it’s time to start using it to fine-tune your audio experience. Here are the steps to get started:

Command to run the equalizer

There are two ways to run PulseAudio-Equalizer on your system. You can either launch it from the applications menu or use a command in the terminal.

To run the equalizer from the terminal, type the following command:




This command will open up the equalizer window, and you can start adjusting the sliders.

Adjusting sliders for audio output

In the PulseAudio-Equalizer window, you’ll see a series of horizontal sliders that control various aspects of the audio output. These sliders represent the frequency bands of the audio spectrum, and the values range from -20dB to +20dB.

To adjust the equalizer settings, you need to slide the bars up or down. The higher the slider position, the greater the amplification of that frequency.

For instance, if you want to boost the bass output, you can slide the lowest slider towards the right to increase the amplification of the lower frequencies. You can experiment with the different sliders to find the optimal settings for your audio output.

You should also take note of the preamp slider at the top, which adjusts the overall volume of the audio output.

Saving and deleting presets

PulseAudio-Equalizer allows you to save custom configurations for future use. The saved settings are known as presets, and they can be loaded into the equalizer window with a single click.

To save a preset, make sure that you have adjusted the sliders to your desired settings. Click on the “Save” button in the bottom right corner of the window, and give your preset a name.

To load a preset, click on the drop-down menu next to the “Save” button, and select the preset you want to use. To delete a preset, click on the “Delete” button next to the drop-down menu.

Select the preset you want to delete, and click “Delete.”
