[QUOTE="drpeeb, post: 6045707, member: 609183"] Just an FYI. I recently discovered the iTunes/ iPod feature called "Sound Check". It's supposed to "normalize" the volume of all of your mp3 songs so you don't get blasted by the loud ones or need to crank up the low ones (of course subsequently getting blasted by the loud ones!). I've tried it since yesterday, and it seems to work good. iTunes scans all of your songs and apparently assigns a volume reduction or increase to each song, depending on how loud the song file is compared to all the others. For example, a modern song ripped very loudly would need its volume reduced, whereas a quietly recorded song maybe from the 60's or 70's would need its volume increased. I've read that iTunes makes a determination for each song and puts the required volume change info in the ID3 tags*. The only complaint I have so far, and it's fairly minor, is that when you're in the middle of a song and want to forward to the next, my iPod seems to "forget", or stop using, the volume change factor just a split second before actually jumping to the next song. So, the problem occurs on loudly ripped mp3's: I get just a very momentary louder piece of the current song before the iPod jumps to the next song. A little irritating, but not terrible. * I've also looked at the ID3 tags after letting iTunes scan all my mp3's and assign its volume change data. The volume change data seems to be put on the "Comment" line, and it looks like a long string of random characters. Here are two examples: From one of my louder mp3 files: 00001B18 00001984 00004E9A 00004E72 0002E29F 0001D2FA 00008000 00008000 000098FA 00000000 From one of my quieter mp3 files: 00000150 000001BA 000006D5 000007B1 0002E675 0002E675 00004ECC 00004CB7 0002E630 0002E675 Not sure what these mean.
