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/)

Impressive, thanks heaps for making this, and for making it open source! I use it with my Kali LP6-v2 and I am impressed.

As an audiophile since childhood, I have always used a 10-band equaliser on all my devices, including my Creative SoundBlaster card. I recently purchased a mini PC that lacks this feature; the above APO with Peace interface it works perfectly to tune my 5.1 home theatre with plenty of options for Windows 11. Love from London!

Great app! I have an old audio system, and this app is perfect for controlling sound frequencies New design is nice

I am now just an old guy(70), that appreciates great music. I used to be the sound tech for many of the local bands "back in the day". I output my PC via USB to a Tascam US-1641, then through a dbx-DriveRack PA+, Bi Amped through 4000 watts on the bottom, and 2000 on the mids-high, 2 channels. I became "tired" of Win10 default sound and didn't want to have to go to the rack for every song, so I searched for good Win10 EQ's. Here I am. I cannot give this program,(app?), enough stars! It is so fantastic, that I took the time to register with Soundforge, so that I could just give credit to this program. I have never done this before, but this time I couldn't let it slide, it is so impressive, that I had to give my opinion for this super feature. I am sure that some will find this program useless, and if that's the case, I strongly suggest to look for a different system, ( amps, speakers, etc.), instead of trying to use software to fix an unfixable situation. I want to thank the designer of this program(app) whatever it's called these days, for the time spent building this, and sharing it for all of us so that we can "pull" everything from our systems.
