BS FAG

BS FAG is an easy-to-use Windows tool that can normalize the volume level of multiple video clips. It offers support for AVI, FLV, MPG, MPEG, MP4, 3GP, 3G2, M4V, MOV and WMV videos files.

Hassle-free installation and user-friendly GUI

The setup procedure is brief and uneventful. As for the interface, the tool adopts a clean window with an intuitive layout, where files can be added to the task list with the help of either the file browser or drag-and-drop support.
The file list shows the name, duration, audio settings, progress, gain and full path for each video. By applying default settings, the audio stream of all clips will be normalized to 89dB (without clipping).

Customize output settings

Users may modify output options when it comes to the audio sample rate, bit rate and custom parameters, custom volume level (in dB, with or without clipping), as well as ask the app to replace original files, restore the audio format, and so on.

Evaluation and conclusion

The tool has minimal impact on PC performance, since it runs on low CPU and RAM. There were no kind of issues in our tests, as BS FAG did not hang, crash or pop up error dialogs. It fixes audio gain quickly. To sum it up, this app offers a straightforward solution to normalizing the volume level across multiple video clips of various formats, by applying default or user-defined settings.
