DownloadEqualizer 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.
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/)
Requirements:
- Windows Vista or later (currently only Windows 7, 8, 8.1, 10 and 11 have been tested)
- the application must not bypass the system effect infrastructure
(APIs like ASIO or WASAPI exclusive mode can not be used)
Equalizer APO is best 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.

I really don't know what user01 is talking about. I absolutely love Equalizer APO. I have been using Equalizer APO for some time now and it is the easiest way to have a system-wide equalizer. My stereo sounds awful when connected to my PC, but Equalizer APO makes it sound fine. Thank you so much for creating this software :)

With Realtek audio, I couldn't EQ my audio. Good headphones and terrible equalization :/ Equalizer 1.3 required a lot of experimentation to get a setting that worked. Version 1.4 does it all for you! Just fire up the configurator, it restarts the service and you're good to go - no rebooting required. THANK YOU SO MUCH for these improvements!
