foo_r128norm (EBU R128 Normalizer) is a third-party digital signal processing (DSP) plugin for the foobar2000 audio player. It actively normalizes audio volume during playback by using a running windowed calculation based on the EBU R-128 broadcast loudness standard. This ensures that tracks with wildly different recording volumes play back at a consistent, comfortable loudness level without manual volume adjustments.
Follow this step-by-step guide to download, install, and configure the plugin. Step 1: Download the Component
Make sure you have the foobar2000 player installed on your system.
Search for the component file (typically named foo_r128norm.fb2k-component or archived as a .zip file) on trusted developer communities like the Hydrogenaudio Knowledgebase or community-maintained databases like foobar.hyv.fi.
Save the file to an easily accessible location, like your Downloads folder. Do not extract it if it downloads as an .fb2k-component package. Step 2: Install into foobar2000 Launch foobar2000.
Open the Preferences window by clicking File | Preferences from the top menu or pressing Ctrl + P. In the left-hand menu tree, click on Components.
Click the Install… button located under the active components list.
Browse to your downloaded file, select it, and click Open. (Alternatively, you can just drag and drop the downloaded file directly into the components list area). Click Apply or OK at the bottom of the window.
A prompt will appear asking to restart the player. Click OK to allow foobar2000 to restart and load the plugin. Step 3: Enable the DSP Plugin
Installing the component does not activate it automatically; you must add it to your playback pipeline: Open Preferences again (Ctrl + P).
Navigate to Playback and expand the menu to select DSP Manager.
You will see two columns: Available DSPs (on the right) and Active DSPs (on the left). Locate EBU R128 Normalizer in the Available DSPs column.
Select it and click the <= (Add) button to shift it into the Active DSPs column. Click Apply and OK. Step 4: Configure and Use
Adjusting Parameters: While still inside the DSP Manager, you can select EBU R128 Normalizer under your Active DSPs column and click Configure selected. This will let you tweak target loudness parameters if the specific version of your plugin supports adjustment sliders.
Seamless Playback: Once active, the plugin immediately begins calculating and smoothing out the volume levels across your playlist in real time.
