Ok - so I have a mp3 collection, and some of the songs are louder or quieter than other since I screwed up when ripping them over the course of years. Some were even transferred off of cassette tape.
I think I need an audio normalizer program. I searched the forums and downloaded mp3trim.
My question is - how do I determine a baseline volume level I’m happy with in one of my mp3’s, and then how do I get the other 10,000 or so mp3’s I have to all play at the same level?
I don’t have some of the original cassettes or CD’s anymore, so some of the songs that need fixing can’t be fixed by re-ripping them. Others can.
Alternately, is there a program that will run a batch job and do the same?
