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.
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 and 10 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.

Really good system-wide EQ. Perfect for correcting speaker and room coloration. Comes with a nice interface to edit the settings in real time without having to open the text-based config files. I had to swap my speakers on my desk, and Equalizer APO works great with swapping the left and right channels of the SPDIF output of my Sound Blaster Z This is the one which works on Windows 10 apart from Dolby Atmos

Hi, after a couple of years with equalizer apo I can say a few thing. It enhances your listening anyhow, but the equalizer itself introduces phase shifts. The good is that you can donwload vst (supported in the form of .dll) to be used as an embedded plugin (I downloaded lkjb QRange, a phase linear equalizer) that will correct and align phase shifts and your listening will make a quantum leap in a matter of minutes. I use a pc source through its usb audio exit, a Pioneer SC-LX87 with its ES9016 SABRE32 Ultra DAC 32/194 and a very good pair of Heco The Statement speakers and, given a good chain, equalizer apo and the plugin will make your sound more focused, clear and enjoyable. I mean that you can have real enhancements even if you start from a good chain. The down with this plugin is that it introduces delay thus it is not suitable for videos, watching tv , movies or any other video source.
