Gapless Music Playback Issue

I feel like this issue began with iOS 13, and the update to iOS 13.1.1 did not address it. iOS 13 appears to not recognize when an album should have gapless playback. It appears to only have this issue with the MP3 files I’ve synced to my iPhone, but .m4a files playback just fine. These are the same MP3 files I’ve had no issue with in the past on an iPhone, and they play correctly in the iTunes Library I’m syncing them from. I don’t have the music synced to any other iOS 13 device to know whether or not it occurs with those, but the issue doesn’t happen with an iPod Nano I have a lot of it synced to. This also does not seem to be specific to the built-in Music app as I’ve downloaded a few other music apps and happens with those as well.

Yes, I am having the same issue! I posted about it last week but since I didn't label it "gapless playback" I didn't get any replies or responses. I'm kind of a music nerd when it comes to this stuff, and since I just got the Abbey Road 50th Anniversary Edition, it's driving me crazy that I can't properly listen to the long medley without split-second gaps in between the songs. These are mp3 files as well -- I haven't tested to see if m4a files play correctly, but I will. I'm hoping Apple resolves this issue soon in another update.

I’m experiencing the same gap issue but also something more: all my music is converted from cd to mp3 and since I installed iOS 13, something really strange is randomly happening. Some songs just...don’t end: instead if changing to the next one, the songs repeat about the last minute again, while the display shows -0:00.

Did someone experience the same issue?

I absolutely have no idea how to fix it. If I reset my iPod 7G and manually put the whole music collection again (a lot of work) some other different songs will be “randomly” affected.

Help :-(

From a Windows 10 user perspective with latest iTunes 12.10.2.3 [until now] and dealing only with ripped material; the problem definitely occurs both with .aac and lossless .alac files when you start playing a track approx. less than its last 8-10 seconds before the (supposedly gapless) flowing the next one; you notice a brief silence between tracks which shouldn't be there, as a spectral analysis and playing of the same files with e.g. Foobar2000 confirmed.


But, if you let iTunes play at least the last 10 seconds of the track the gapless transition is OK, and the more so when playing tracks seamlessly from start to finish. So it definitely seems to be a data buffering matter (?) Strangely, mp3 files (even very old ones) aren't affected by this bug. Long story short, will check next iTunes updates to see if the matter is addressed but from this side isn't that annoying when 'normally' playing a gapless album.

I have always noticed this to be the case, though. Whenever I rip a CD of my own, I test it out to make sure it is gapless, and if you do just try to play the last 10 seconds or so on an iOS device, you will hear that gap. Instead, I try to play the final 20-30 seconds, and it's almost always good. The only other times it is not good is, what I would think, is just a coincidence, because then I will play the entire song and have no issues smoothly going to the next track without a gap. And the same goes for when I would try to do the same in iTunes on a PC or Mac.

You’re noticing this with iOS 12? I feel like I only started having it occur with iOS 13. I also went ahead and updated to iOS 13.1.2 and the issue continues. I’ve also deleted an affected album from my iPhone, then synced it again, and the issue continues. The only thing I haven’t tried is removing it from the iTunes Library, then adding it back again. If that resolves the issue, I guess it could be worse.

I’ve updated to 13.1.2, but the problem persists! All of my albums still have gaps between tracks even though they are meant to play through gaplessly. I did not have this issue until I updated to iOS 13. I’ve submitted this bug a week ago before 13.1.2, but they still haven’t fix this issue yet and it’s starting to get really annoying. I read on some forums from July that this problem already started in iOS 13 beta so they have had several months to fix it now. How can they screw up on such a basic and simple functionality and not fix it in the public release?

The release notes don't state anything about resolving a gapless playback issue. In fact nothing about music is even mentioned. "Overview

The iOS & iPadOS 13.2 SDK provides support for developing apps for iPhone, iPad, and iPod touch devices running iOS & iPadOS 13.2. The SDK comes bundled with Xcode 11 available from the Mac App Store. For information on the compatibility requirements for Xcode 11, see Xcode 11 Release Notes."
