Back from Hawaii(and Married)(& broke LOL)
From reading some really old posts, if I understand it correctly, prevent clipping will bring your track as close as possible to your target db without clipping(doesn't compress or limit as some people thought). IE, I'm at 89db now, but I aim for 94db. Now that track clips at 94db, and at 93db as well, so MM raises it to 92db and file plays fine(no clipping). So that leaves an offset of +2db(+ means quieter) in the track volume field(which is relative to the 94db target I set in MM).
Now, the tracks that don't clip at all, will usually be at +/- .9db or less from the target 94db.
Now that I have actually did track leveling, what should I do about the track tags? I originally Analyzed the volume and MM put that in the tag info for playback by players that read tags. When those players such as MM etc read the tag will they now play the song at twice the loudness or softness since the track its self is adjusted & the tag has the same info? I suppose it would just be best to clear/clean the volume leveling tags in the track to alleviate any confusion for the players?
I did screw around with Audacity 1.3 Beta to see the difference between a untouched track and one that has been track leveled to 2 different db levels. I don't know what a lot of the options do or much about the program its self even, but in my spare time I'll try to read up on it hopefully.
Dug up these really old threads/posts that appear to be from the inception of track leveling in MM. Thought they might be of some use to others in there search. Rusty's post on Wed Feb 18, 2004 states:
3) Level Track Volume: This functionality allows users to actually modify their _MP3s_ so that they are leveled to the Baseline Volume Level (without affecting playback quality). This is done using the same mechanism as MP3 Gain, and is very useful if you want to export MP3s to a portable player that doesn't have volume leveling of its own.
