Video Volume Booster is a free tool to increase the audio level in all types of video files. This is a very useful tool if you have come across video files that have an audio track that you can barely hear even with 100% volume in your media player software. It uses the open-source FFmpeg media manipulation toolkit to change the volume level inside the video files. It does not alter the video stream inside the video files at all. You can think of the Video Volume Booster as a permanent amplifier for the video files.
The user interface of Video Volume Booster is very easy to follow. You have to add the video files that you want to modify. Since it is using FFmpeg, it supports almost all video file formats including AVI, DIVX, XVID, MPEG, MPG, MKV, RM, RMVB, FLV, MOV, MP4, ASF, WEBM and many more. You can add as many video files as you want. After adding the files, you can click on the Optimize button and it will make the necessary changes before saving them to the specified folder. All the video files in the list are processed one by one and are copied to the output folder.
By default, it amplifies the audio stream by 10 decibels. But you can modify the settings and change the amplification level. The developer of this software advises that amplification should be kept in the region 10 decibels to 20 decibels. Among other things, you can change the output folder, output name and the audio codec for the audio stream. You can edit both the bitrate and the sample rate for the audio coding. If you know your way around FFmpeg, then you can also change the FFmpeg command line for the video files in the settings.
