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.
- 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/)
- 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.
I've been using it for a while now. It's awesome. Really easy to use. Clean, intuitive interface. The configuration files are edited and applied in real time. Had a few bugs where I needed to reapply the configuration and restart, but it only happened twice in a year or so.
Works well for me. Run editor.exe to change settings.
Very nice! :) Works well on Win10 x64
I implemented APO in my home listening room. With APO Equalizer and Room eq wizard I've extremely improved sound quality especially in low end frequencies. Program is working fantastic. I never had any problems on windows 8. Many people are not aware how Room acoustics impact sound quality. After correction sound from my loudspeakers is very close to good headphones. Many thanks for authors... Good job.
Been in the music/sound business for 30-years. Nice App! On installation, it picked up our recording studio USB input hardware and integrated just fine. Now we can play EQ'd mixes to musicians without having to re-route from the mixer computer software and introduce latency issues. Nice job!
