8 Led Zeppelin tracks are all like this, the next track will be loud, the
9 next track "in the middle", in other words it's Goldilocks and the three
10 bears with audio tracks.

19 What you're looking for is called "replay gain" (alternative spelling,
20 "replaygain"). Basically, it's a two-step process : (1) analyze the
21 'effective loudness' of a track, and (2) add a tag indicating the
22 difference between the measured 'effective loudness' with a reference level
23 of 89 dB SPL
27 The above wiki article might be out of date with regards to the available
28 software. Try asking around in the HydrogenAudio forums. They are a bunch
29 of friendly guys ;-)

32 any forum discussions for several years.)
