Equalizer APO (Audio Processing Object) is one of those audio tools that take a while to set up but once you manage to, it helps you improve both the quality and power of your sound.
The degree of difficulty that comes with the application only applies to the installation process. Configuring and using it is actually quite simple. And that’s because Equalizer APO is a Windows equalizer that does not display a graphic user interface. Instead, you use TXT files to change the settings of your audio output.
It is a bit strange but practical nonetheless. During installation, Equalizer APO allows you to choose the audio device you want to install the APO to so you need to know which one you need to enhance. If by any chance you get it wrong, you can change the device at any time. The application displays a complete list of connectors, device names and makes you aware of which ones support.
Because it does not display a graphic user interface and works beneath the hood of your operating system, Equalizer APO delivers prompt results without leaving any traces in your system resources. And with that in mind, It is not only reliable, but it is also efficient.
Equalizer APO Features:
- Virtually unlimited number of filters
