I have thousands Video flv/avi files, which are all songs only. Some of them are high in volume and some are low. Every time the song ends I have to up or down the volume at once..to escape my ears ruined by headphones... and by woofers, save my life from my neighbor sleeping after hard-earning all the day long. :-(
Any idea to make all files sound equal? Does such kind of application/software exist? Any converter that may convert all audio files into same volume?
I know iTunes has sound-check option but can it convert? If I want to write CDs, does any burner have the feature like this, to burn in equal sound?
I welcome any suggestions.
You may have to extract the audio tracks, use something like mp3gain to put them all to a set level, and then recombine them with the video. It's not pretty and is time-consuming. – None – 2012-10-27T17:13:00.640
Both Mikio and dmcgill50 answered correctly. You will have to transcode the files to normalize the audio output. Keep in mind transcoding data from a lossy format is destructive since compression artifacts are cumulative. You may notice a quality decrease. – OCDtech – 2013-01-14T21:02:02.480
