Hmm. Normalization means you don't have the change the volume between podcasts, but better than that would be dynamic range compression. A podcast with both loud music/effects/screaming and quiet/normal dialogue would be "evened out". You wouldn't have to adjust volume even within a podcast. I don't know of any audio player (desktop or mobile) that has this feature. It would be perfect for podcasts/audiobooks.
