I hope this is the right forum and that this topic hasn't been beaten to death. I apologize if I'm wrong on either of these. I searched but didn't find the answer I was looking for. Of course, the amount of info here is a bit overwhelming smile.gif

I used dbpoweramp to rip to FLAC, then generate 320kbit CBR MP3s. ITunes plays them gaplessly as does foobar2000. However, my iPod (5th generation) does not. There's a teeny "gap" (more like a glitch). My iPhone 3G doesn't play them gaplessly either although the "gap" is more like a click. Meanwhile, MP3s generated by iTunes play on the iPod perfectly.

I know, years ago, there was a lot of noise about apple not supporting gapless. But, I thought this was all resolved. Certainly, it appears to work fine if the MP3s are encoded with iTunes.

Is this a well-known problem? I found some other posts that seemed to say that LAME encoded MP3s (which is what dbpoweramp uses) play gaplessly on iPods. So, I'm puzzled as to while I'm having this trouble. I'd appreciate any help or suggestions.

As I have said, iTunes scans my Lame mp3 files during the import process. I can even take iTunes mp3 or iTunes AAC files from one computer, copy them to another, and iTunes on that system will scan for gapless playback. The scanning always occurs regardless of the encoder or ripper. I also don't think that iTunes stores the gapless playback information in a separate file, I know this. Many of us (on a different set of forums) have been observing iTunes' behavior for years. It stores non-embedded album artwork, gapless playback information, playlists, ratings, and various other aspects all in a separate file from the lossy files. There is something wrong if iTunes is not scanning your files for gapless playback. Seeing anything regarding volume means that you have Sound Check enabled.

The first step would be to disable Sound Check, delete the files from your iTunes library, restart iTunes, and import the files back in. Gapless tag/medata or not, iTunes will still scan the files. I suggest that you delete all of the problematic tracks from your iTunes library, restart iTunes, and then add them again. You should see the "scanning for gapless playback" message when importing over 15 files.
