Volume Normalizer Master

You may be looking for a simple way to adjust the volume of your audio and video files, without having to navigate through multiple menus or posses in-depth knowledge of audio editing techniques.
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.

Can batch process files

After launching the application, you need to load the list of files that should to be processed. You can add them individually or have the program scan an entire folder for compatible video and audio files. It supports various formats, including AVI, MPG, MKV, WMV, MP3, WAV, M4A, OGG and FLAC.
Once you have chosen how the files should be modified and selected the output folder, the program can process all of them in one operation.

Multiple normalizing methods

The application can adjust audio volume in various ways. The files can be processed individually, without taking into consideration the other tracks in the processing queue, or collectively, so that all the output songs or videos end up with similar volume levels.
When processing the files separately, they can be adjusted by peak or RMS volume detection. You can also change the sound level directly, by specifying a custom dB value or percentage.
If files are being normalized collectively, you can have the application calculate a weighed or arithmetic average of all the tracks' sound level, ensuring that the output files do not vary in volume relative to each other.

Easy-to-use, but lacks documentation

Volume Normalizer Master is aimed at those who need a simple and hassle-free method of adjusting the sound level of audio tracks. However, while it features an intuitive user-interface, it offers no detailed explanations when it comes to the best situations to apply certain normalizing methods.
Moreover, it is not possible to play audio tracks within the application or test the effect of various editing operations before processing files.
Overall, if you are looking for a straightforward tool that can help you adjust the volume of multiple audio and video files in one operation, you should try Volume Normalizer Master.
