The Best Free Windows Sound Equalizers

Windows 11 has no built in sound equalizer, but there are different free options available. We show you the best free Windows equalizers and help you decide which one to choose.


Navigating sound equalization on and can be a bit perplexing, primarily because Windows itself doesn't offer a built-in audio equalizer. This absence often leads users to wonder about their options for customizing audio settings.

has opted not to include a native equalizer in Windows and this is still the case with Windows 11. This choice aligns with their approach of providing a streamlined, user-friendly operating system while allowing third-party developers and hardware manufacturers the flexibility to offer specialized audio solutions.

Given this scenario, users seeking to fine-tune their audio experience can turn to various third-party solutions. These range from driver-based equalizers for specific hardware, like the Realtek audio chipset, to comprehensive software solutions like Equalizer APO and Peace Equalizer interface.

Realtek Windows Equalizer for Compatible Audio Chipsets

The driver for the Realtech chipset, which is installed in the vast majority of Windows systems, luckily comes with a sound equalizer of its own. Here is how to use it:

  1. Open “Sound Settings”
    After a right mouse click on the speaker icon on the right side of the taskbar you can directly open the “Sound settings” from there.
  2. Open “More sound settings”
    Scroll down to “Advanced” and click on “More sound settings”.
    Windows 11 - Settings - Sound

Equalizer APO for Windows

Equalizer APO for Windows upgrades your system with a parametric/graphic equalizer implemented as an Audio Processing Object. Microsoft writes:

“Windows allows OEMs and third-party audio hardware manufacturers to include custom digital signal processing effects as part of their audio driver's value-added features. These effects are packaged as user-mode system effect Audio Processing Objects (APOs).”

The nice thing about this freeware equalizer is that you can activate it separately for any audio-device which means you get both an input equalizer for your microphone audio and one for speakers, headphones or line-out. Here is how to set up Equalizer APO in Windows 11:

  1. Download and Install Equalizer APO
    Download Equalizer APO from the official site and run the installer. Select the devices for which you want to use Equalizer APO during the setup.
    Equalizer APO applies its audio processing effects at the device level. By choosing specific audio output devices (like your speakers or headphones), you ensure that the equalizer's adjustments are applied correctly to the audio output of those particular devices. This targeted approach allows for more precise and effective audio enhancement, as different devices may have different audio characteristics and may require unique equalization settings.

  2. Open the Equalizer APO Configuration Editor
    Launch the Equalizer APO “Configuration Editor” from the Start menu.
  3. Select Mode, Audio Device, and Channel Configuration

    Instant Mode:

    When you modify settings in “Instant Mode”, the changes are immediately applied to the audio output, allowing you to hear the effects of your adjustments without delay.

    Device: This option is used to select which audio device you want to apply your EQ settings to.

    Channel Configuration: Useful for setting up and adjusting the EQ for different channels individually. This is particularly important for multi-channel systems, like 5.1 or 7.1 surround sound systems, allowing for customized equalization for each channel.

  4. Configure Equalizer APO
    The Equalizer APO Configuration editor uses a modular approach, where different elements are stacked upon each other and can be turned on and off via a power button. Per default you will see three of them – “Preamplification”, “Include”, and the “Graphic EQ”. More can be added below clicking the green “+” button.

    – Preamplification: This controls the overall gain (volume level) before the signal is processed by the equalizer. Adjusting preamplification can either boost or reduce the volume without changing the tonal quality of the sound.

    – Include: example.txt: This option allows you to include additional configuration settings from a text file. By specifying an ‘example.txt' file, you can import pre-defined equalizer settings or configurations, which can be particularly useful for complex setups or sharing settings between systems.

    – Graphic EQ: The Graphic Equalizer section provides a user-friendly way to adjust the balance of different frequency bands visually. You can manipulate sliders corresponding to various frequencies to adjust the sound profile. This feature is great for making precise adjustments to specific frequency ranges, like enhancing bass or reducing treble.

  5. Available filters and modules

    Equalizer APO provides various filters and modules for detailed audio customization:

    Parametric Equalizer: Allows precise adjustments to specific frequency bands. Ideal for fine-tuning audio characteristics.

    Graphic Equalizer: Offers a visual interface for adjusting frequencies, suitable for quick and intuitive modifications.

    Low/High Pass Filters: These filters control the passage of low and high frequencies, essential for managing bass and treble.

    Bandpass Filters: Target a specific range of frequencies, excluding others.

    Notch Filters: Useful for eliminating unwanted frequencies, like hums or buzzes.

    Gain: Adjusts the volume level of different frequencies or the overall sound.

    Delay: Used to create an echo or delay effect in the audio signal.

    Reverb: Adds reverberation effects, simulating different acoustic environments.

    Convolution: Advanced filter that uses impulse response samples to simulate specific acoustic environments or speaker characteristics.

    Compression: Manages the dynamic range of audio, balancing loud and quiet sounds.

    For a more comprehensive understanding, refer to the Equalizer APO documentation for in-depth explanations and usage instructions.

  6. Review settings with the “Analysis Panel”
    The Analysis Panel in Equalizer APO provides visual feedback on the audio signal being processed. It typically shows information such as frequency spectrum, which displays the strength of various frequencies within the audio. This allows you to see the impact of your equalization settings in real-time, making it easier to identify and adjust specific frequencies that might need boosting or reduction. Additionally, it can display other parameters like phase and delay, offering insights into the audio characteristics that can inform your equalization choices.
  7. Saving Equalizer settings and using presets
    You can save your personal equalizer presets as .txt-files and import them later if needed. Using you can find optimized presets for specific audio devices such as headphones, speakers and music types from other users. A more comfortable way to use Equalizer APO are plugins that offer a separate interface, such as Peace Equalizer (see the next section).
