Any chance you could figure out how the Ipod's soundcheck feature works and allow foobar to write replaygain info in sound check form?

%ITUNNORM% = 000002B9 0000027C 00002278 000019E0 000194BF 00018F16 00006E3D 00006E3E 00018870 00018F16
Add a new un-soundchecked mp3 to iTunes, let it scan, then load it up in Foobar. Get Info in foobar. For example, my new Korn CD has these things in the comment field. Code: [Select]iTunNORM: 000028A5 0000273A 0000730F 000069AD 000186CE 0001119E 00008000 00008000 00002710 00002710
I don't think the Ipod knows what a file tag is. From what i gather its all handled by iTunes. WHich makes sense since the Ipod needs to load as quickly as possible while using as little of its meager processor and battery as possible. I'd guess that those tags are just for compatability with other iTunes clients and as a backup incase the user formats or otherwise loses itunes's db.About the numbers themselves, perhaps the gain values are stored as integers? That would make sense since I think the ipod's processor is int only.
Otto did u find where the database has the soundcheck stuff?
Good work so far!I know you've already found the soundcheck info in iTunesDB, but I'll post this anyway. http://www.ringom.no/espen/ipod/This guy has come up with a untility for adjusting these fields.Hope this is of some help.
I meant out of ID3v1 and APEv2 (the two formats I use), iPod only reads ID3v1
