Equalizer APO is a parametric / graphic equalizer for Windows. It is implemented
as an Audio Processing Object (APO) for the system effect infrastructure
introduced with Windows Vista.
Requirements:
- Windows Vista or later (Windows 7 - 11 have been tested)
- CPU architecture x64 (64 bit), x86 (32 bit) or ARM64 (on Windows 10/11)
- applications must not bypass the system effect infrastructure
(APIs like ASIO or WASAPI exclusive mode can't be used)
Equalizer APO can be used in conjunction with Room EQ Wizard (http://www.roomeqwizard.com/), because it can read its filter text file format.
Please have a look at the Wiki (http://sourceforge.net/p/equalizerapo/wiki/) for instructions on installation and configuration
Features
- virtually unlimited number of filters
- works on any number of channels
- very low latency, which makes it suited for interactive applications
- low CPU usage
- modular graphical user interface
- VST plugin support
- integrates into Voicemeeter (http://www.voicemeeter.com/)

Amazing app that i have been using for over years. It just upgrades my speaker to another premium level. Suggest to embed it inside Windows as default driver for everyone. Perfer to have Traditional Chinese translation.

Ik heb hele goede speakers maar met Equalizer APO komen ze helemaal tot hun recht. Het heeft nog nooit zo goed gehoord als nu. Het programma is stabiel en werkt perfect het doet wonderen. Het is perfecte software. De donkere modus is ook geweldig. Ik ben helemaal tevreden en het is boven verwachting uit. Ik kan het iedereen aanraden. Dankje voor deze goede software, mijn complimenten.

I love almost everything about Equalizer APO; it's been the solution to many of my problems involving audio. The only thing I wish it had was compatibility with NS1 Noise Suppressor; more specifically, I wish it worked with Waves' WaveShell System. I recently paid for the NS1 Noise Suppressor, thinking I could add it to my microphone, but I found out that adding the .dll file didn't work because "Library could not be loaded." As stated before, Equalizer APO is amazing, and the only issue is compatibility with VST3 plugins.

No Windows OS is complete without it, especially if you care about audio and now finally with Dark Mode support. Highly recommended!
