Equalizer APO is a free audio application for PC created by indie developer Jonas Thedering. It’s a sound customization tool that enables users to change the sound coming out of their computers through equalization. It supports creating profiles for different tunings and preferences that they can easily switch between.

Comparable to other solutions like FxSound or Boom3D, Equalizer APO works system-wide and is compatible with various audio devices, whether they be headphones or speakers. It features a graphical multi-band EQ for adjusting individual frequencies, and it’s also frugal on resources, so it won’t affect performance or other computing tasks.

What is Equalizer Apo?

Equalizer APO only utilizes minimal resources on any computers so that it responds faster. Users will experience lag reduction when they utilize the software along with any running apps. This software is solely implemented as an Audio Processing Object which is compatible with computers starting from Windows Vista. 

The audio software is built with an unlimited number of audio filters to choose from, multiple channels support, and easy to use interface with an integrated VST plugin. Twitch streamers will find this audio solution extremely helpful as they need to adjust their audio at an optimal level. Equalizer APO is easy to download and set up on any computer. Unfortunately, the software lacks support to some API-exclusive mods like ASIO or WASAPI. 

How to use Equalizer APO?

Users first have to ensure that there are audio devices connected to the computer so that they will be installed with the audio software. This program will next request for a system restart and it will be ready for opening in the App folder and taskbar launch icons. Users are free to customize their configuration tabs if they are not contented with the default configuration tab. 

They will simply create a new file, add audio devices to be adjusted, select which audio device to amplify, implement a preamplification filter of their choice, view the Analysis Panel for final adjustments, and save the new configuration tab. The new configuration tab is ready for switching on and off through the interface’s power button. Users can have single or multiple versions of configuration tabs that would fit in any audio setup. 

The audio software is created to work along with Voicemeeter for users who wish to have a better audio interface. Voicemeeter has a very familiar interface for audio engineers since it gives intuitive voice mixing consoles. Another software that is best used in conjunction with this audio solution is Room EQ Wizard. Room EQ Wizard is a competent software that allows smart reading of Equalizer APO’s own filter text file formats.

Enhanced utility and easier customization

Now, while Equalizer APO has its own graphical user interface, the implementation is rather basic and leaves a lot to be desired. It will still end up being a bit confusing and unintuitive for a lot of first-time users. This is why it’s often paired with the Peace Equalizer app, which brings a better UI for navigation and getting to know all the former’s features.

Through it, you make adjustments on a per-device basis and choose from the built-in presets to get you started. For more granular control, a multi-band EQ is still there to tweak to your liking, but again, changes are much more straightforward. Adjust your pre-amplification to avoid distortions, and tinker with audio channels, stereo balance, and more through the effect panel page.

Ensuring better audio output

Equalizer APO is a handy tool regarding audio adjustment during streaming. Users only need to make sure that their audio is neither too inaudible or too booming because it can negatively affect their followers. Nevertheless, it is still a highly recommended audio software solution, especially for beginners.
