How To Use

• 1. Add video or music files by pressing "Add" button or drag drop from Windows Explorer. The files will be read for their information. 

  2. Open "Options" if needed by pressing "Options" button.

     • Set "Audio level" to desired volume. Acceptable values are 30.0 dB - 99.0 dB. Ideally is 89.0 dB.

     • Select "Ignore clipping sound" if you wish.

     • Select "Analyze only" to skip gain fixing but show the gain value that could be applied. (v4.2)

     • Select "Replace original files" to activate. Be sure on selecting this option as the fixes will be permanent. 

     • Select "Do not pass" to force rebuild although volume level is already achieved. 

  3. Give check marks on the list to select videos to process. 

  4. Press "Process" button to start the process. 

  5. After finished fixing, the successed result video will be on the same location of the original files and in the list will show gain value applied. 

Enjoy the new videos and music files with proper audio volume level on computers, smartphones, DVD players, TV, anywhere!

Be warned that the audio might be converted as it will alter its quality. Although similar original audio specification will be applied, the result will be more or less different.
