pwagland, apparently there is a new firmware containing 'bug fixes' for your iPod, version 1.2.1. Could you try that one? It seems it can't be downloaded from the Apple site, you need to connect your iPod to iTunes. OK... this seems to have made zero difference. I also removed the gapless info head...

I'm still puzzled by the fact iTunes plays Max' files gapless but your iPod doesn't. Have you tried Max' gapless files on your friends iPod? It could rule out your iPod (or particular model) being the problem. I'll try to get some of Max' gapless files onto different types of iPods at the Apple Sto...

I must say I'm lacking inspiration right now. Let's hope Stephen can find time to look at: * Capitalization of the itunSMPB atom * The missing leading space These two I can look at myself. * The odd bitrate * The missing block of zero's (not sure about this one, is it really missing, could it matte...

it is a hmoov, not a moov. Hhmm. I hope that is some quirk somewhere. I can't seem to find files that have anything else than moov, I've never heard of hmoov and neither has Google. ;-) Heh. I probably should have replied earlier... I think that the h is actually just a length byte that ends up pri...

Well, Max certainly has an odd bitrate here. :) And it has one block of zero's less than the other two. Yeah :-) I think that the odd bitrate comes from the 40(odd)K of zero 'free' padding that max adds, that the other two do not. Also, it has everything the same, except for a missing leading space...

Hmm.. I have just discovered something very interesting.... the iTunes generated file has a very different header. For a start the magic number is different, and it is a hmoov, not a moov. I hope that helps somebody figure out what it all means! Oh.... one other difference... it would appear that ma...

I think that I may have found a problem... iTunes puts all of the tags at the front of the file, Max puts them all at the end. Although that does not explain XLD, which also puts the tags towards the fron t of the files. :-\ Also, both iTunes and XLD spit out iTunSMPB\0\0\0\XCC and Max spits out iTu...

Maybe some more useful information... I assume that cpil is compilation, and that tmpo is tempo, although I can't imagine either of those fields affecting gapless playback. But, both iTunes and XLD spit out capitals, and a leading space.... for consistency, so should Max I guess.... More investigati...

I'm really interested in the files XLD makes... Well... good and bad news... XLD also has the mini-skip when played on the iPod. However, for all three of Max, XLD and iTunes I converted from iPod, iTunes plays truely seamlessly, both Max and XLD have very brief skip... as mentioned before, it is v...

OK, this is even better. Could you try both these sets of tracks on your iPod? Is the upper case one completely gapless? Lower case Upper case Thanks! Well... I could not reliably detect any difference between the two... there was a few ticks in the lowercase version, but they also turned up in the...

Except for the first bit before the data, and I have no idea what that is, the two look pretty similar to me. I don't know if it makes any difference, but the tags are also in a different order as well. I will try to pull down a newer svn snapshot and run that, just to make sure that I am getting th...

That is strange. Since there is no difference between the gapless data produced by Max and by iTunes it shouldn't sound different. It would appear that this statement is not as true as previously believed ;-). Judging by a previous comment in this thread, the important atom is ITunSMPB, and for me,...

Thanks for testing this. Unfortunately I don't think I'll be able to get my hands on a 5G iPod. I'm going to do some tests with a Nano soon though. No problems... I am happy to test... :-) The fact that ALAC plays gapless is not very surprising, due to their nature lossless files generally don't su...

That is strange. Since there is no difference between the gapless data produced by Max and by iTunes it shouldn't sound different. If you let Max convert the FLAC files to Wav and then let iTunes convert the Wav's into AAC does it play perfectly gapless on the iPod? What type of iPod is this? Which...
