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
- Windows Vista or later (currently only Windows 7, 8, 8.1 and 10 have been tested)
- Sound card driver must support APOs (this includes most onboard sound drivers)
- 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.hometheatershack.com/roomeq/), 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.
Awesome app. I just got some new headphones that were a bit bass heavy for my liking and this allowed me to tweak things exactly to my liking. Thanks.
Wow. Used in combination with RoomEQ Wizard. Amazing results for room correction.
A fantastic way to implement an always on Equalizer in your PCs playback system. It works on the chosen Outputs and e.g. allows you to get rid of room modes with the (big) help of RoomEQWizard generating the needed filters. You even have the possibility to implement some level of programming for the configuration to do some amazing stuff. 5 Stars this is great!
This is brilliant! Super natural crisp sounds. I never thought my simple laptop could become this hi fi! Amazing sound improvement, speechless! Feels like i'm watching movies in theaters! fantastic bass! This is hi fi sounds indeed! Great when combined with equalizer apo gui, makes things so much easier. Big thanks for making it available for free.
Fantastic. I suppose I should play with all the settings but I all I wanted was a volume boost as I have a laptop. The example file when changing the preamp to 0db gave me all the boost needed. Great little program
