Lossless adjusting of loudness for MP3 and AAC files
Authored by: atverd on Apr 14, '05 02:05:00PM

Try it without scripts first.
1. Copy couple of tracks from iTunes to your Home f.e.
2. Rename original tracks in iTunes in some reversable way (Add "original" to the title end of each track f.e.).
3. Put aacgain to your Home too.
4. Run it like this from Terminal: ./aacgain -r -p -k "name of track1" "name of track2"
Enclose each name in quotes ("") and separate names by space.
5. It should show you a lot of things and among them at the end it will tell how much gain it added or removed. If it says "no adjustment needed" then your track already fine and you will not hear any difference. Otherwise go next.
6. Import them to iTunes and play original and imported - even with gain 1 you should be able to hear the difference.
