Volume Normalizer Master is an intuitive application, designed to help you modify the volume of various types of video and audio files, singularly or collectively. This software normalizes audio or video files by peak volume detection and RMS volume detection.

ReplayGain software stores 'loudness' information in the audio file's metadata header. This metadata is supported in a variety of applications, but not all player software (iTunes, Windows Media Player, etc.) and many hardware media players. Volume Normalizer Master creates normalized new audio or video file, which can be played by all player software or hardware media players.
