Equalizer APO: Parametric Equalizer for Windows

Equalizer APO is a parametric equalizer for Windows that allows you to customize the sound output of your audio devices. It works system-wide and can be used to tweak frequency response curves, add bass/treble adjustments, apply filters, and more to shape your audio playback to your preferences.

What is Equalizer APO?

Equalizer APO is a powerful parametric equalizer and audio processing tool for Windows. It works as a pre-mix audio effect that allows you to make precise adjustments to your system's frequency response curves to customize and enhance the sound output from your speakers, headphones, or other audio devices.

Some key features of Equalizer APO include:

  • System-wide audio adjustments - It works at a system level rather than only within specific apps, allowing you to tweak sound globally across Windows.
  • Extensive parametric EQ capabilities - Manually adjust gain levels across a wide range of frequencies to shape your preferred sound signature. Set different EQ curves per audio device.
  • Bass/treble and pre-amp controls - Convenient sliders to quickly boost or attenuate low and high frequencies.
  • Filters - Apply high/low pass, peak, notch, and other filters for additional sound-shaping capabilities.
  • Per-application profiles - Define custom EQ settings on a per-app basis so your audio tweaks only apply when using certain programs.
  • Lightweight and open-source - Uses minimal system resources and is freely customizable.

If you want fine-grained control over how audio is processed and enhanced on your Windows PC for music, movies, games, and voice calls, Equalizer APO is an excellent free option to consider. The advanced parametric EQ features combined with flexibility in routing audio signal chains make it a powerful sound adjustment toolkit for experienced audio enthusiasts.
