R128GAIN is a software application that enables you to easily normalize the volume of several of your audio and video files, with a minimal amount of effort.

Cluttered GUI, yet well-drawn documentation

The installation process can be bypassed with ease, while the interface you come across might seem a bit messy and crowded at first. It consists of multiple buttons, several drop-down menus and a few slider bars. However, you should know that some explicit Help contents are provided online and thus, all users can learn how to handle R128GAIN.

Choose compliant and adjust a few parameters

This utility enables you to upload multiple items in the same time, with the help of a file browser, while there are a lot of options to adjust. For example, it is possible to choose between several compliances such as, EBU R 128-2011, ATSC A/85:2011 and ReplayGain.
Aside from that, you can change algorithm and peak type (true, sample), as well as adjust gate, reference loudness, and ReplayGain calibration.

Input commands and change output extension

You should know it is possible to change the output format to MKV or FLAC, overwrite the target or original file and choose image size from a drop-down menu.
It is possible to input commands with the help of a dedicated pane, so that power users can easily work with this utility and make multiple changes to the uploaded songs or clips.

A final evaluation

The computer’s performance is not going to be burdened, as CPU and memory usage was low at all times. The interface might prove a bit difficult to handle for beginners, Help documents are provided online and the response time is good.
To sum up, R128GAIN is a pretty efficient piece of software which aids you in normalizing the loudness of all your audio and video files.
