As far as I understand, the sound level of any file containing audio, such as music or video files, is defined in the file itself. Thus, setting the sound level effectively changes the percentage of the max sound pressure defined in the file. (Please do correct me if I'm wrong)
My question: Is it possible to set an "absolute" sound level so that the media files being played actually follow that setting? This way there won't be media files which are louder or quieter than others at the same sound level setting.
