Equalizer APO does not work? A common mistake you make is to forget to activate your reading device in EQ APO. The screensho shows that the AMD HDMI output is enabled, it is my favorite interface to send audio to the Surround Sound Processor. By activating it in this menu, we can be sure that the filters we have defined will be applied if our interface is supported.
What is Equalizer APO?
Equalizer APO is a parametric / graphic equalizer for Windows. It is implemented as an audio processing object (APO) for the system effects infrastructure introduced with Windows Vista. Features: – almost unlimited number of filters – works on any number of channels – very low latency, making it suitable for interactive applications – low CPU usage – modular graphical user interface: – Windows Vista or higher (currently only Windows 7, 8, 8.1 and 10 have been tested) – Sound card drivers must support APO (this also applies to most embedded audio drivers) – The application must not bypass the system effects infrastructure (APIs such as the exclusive ASIO or WASAPI mode cannot be used) Equalizer APO is best used in conjunction with Room EQ Wizard.
Therefore, make sure that all the playback devices on which you want to perform processing are enabled and do not forget to restart your computer after installing Equalizer APO, otherwise it will not work. If you need to change these settings in the future, they will be available via C:\Program Files\EqualizerAPO\Configurator.exe or wherever you have installed the software.
