Are you referring to sector boundary errors?  They should be removed in pre-mastering anyway. 

 

I've never had such an issue with FLACs.  Not once with literally thousands of recordings, both commercial and my own recordings.  Rockbox, iDevices and Foobar all play them without issue (and without the need for a cue sheet).

No, just basic frame/block padding. You've never had a problem with FLAC because pretty much everyone doing FLAC playback is using Xiph's libraries which automatically handle padding removal during decoding. You will also have similar results with Vorbis and maybe Speex and Opus (not sure since those two are for streaming, not for fixed-length recording).

The issues with Apple playback are likely due to the fact that there is no one freely usable set of AAC and ALAC decoder libraries available. This means everyone doing AAC/ALAC decoding is licensing decoders from one of several different companies or rolling their own. Either way it means different and inconsistent capabilities across vendors and maybe even across different devices from the same vendor. If Apple is embedding timing information in their files and iBasso is using a decoder that does not make use of this information then yes, there will be playback gaps where there should be none. If someone can confirm this then it should be reported to iBasso as a bug.

All of which really, really makes me want iBasso to fix up their Ogg Vorbis tag handling or for someone to figure out how to put a half TB on a transflash card that doesn't cost an arm, a leg and a spleen.

I get it.  I use FLAC almost exlusively.  I have zero experience with Apple's proprietary formats (and have no desure to experience them), but you may have just explained the mysterious issues musicheaven was having with playback of his Apple iTunes files on the DX50. 

 

Incidentally, I should add both the FiiO X3 and the DX50 to my list of devices that have had no issues with gapless playback of FLAC files.

Speaking of:

Has anyone out there been using their DX50 (without external amp) with a really high impedance IEM like the ER4S or SM64?

Without amp, I normally set volume at around 240 when listening with my ER4S. Using firmware 1.2.6.

I'm currently using the DX50 with my Heir Tzar 350, and on high gain and around 220 vol they sound very, very, VERY well indeed :).

Sometimes I really love head-fi, this has got to be the only site on the net where you check in to see what's going on FW wise for an MP3 player and run into page after page discussing the definition of gapless. Carry on boys, it's not every day I get to watch the head-fi debate club flex their muscles over the definition of the word gapless and how it should be implemented. Someone pass me some popcorn.

Oh, I feel you, brotherin.

 

I have the urge to unsubscribe to this thread because of the overload on 'gapless' definitions, and why it is a necessity to life..too bad, I need it for my updates.

To answer your question, nope. Half the stuff on my SDCard is either live performance or trance mixes that need gapless. I'm on FW 1.2.5 which still hasn't fixed my file scanning and player freeze up problems. Can't remember who it was complaining about it, on 1.2.5 my gapless playback worked fine and I was using ALAC and AIFF files as well FLAC in 16 and 24 bit files. If you're having problems with gapless playback on 1.2.5 and not on an iPod or iTunes there might be something else at play messing up the gapless playback. If you're reencoding your original files try using another encoder/ripper and see if that helps. The only thing I did with my ALAC files was I stripped their tags and kept only track no. Artist, album name, etc and gapless worked fine for me.

Yeah sounds like the encoder might have been at fault but again I used the same converted files on the iPod and no problems there so really makes me wonder.

The scanning problem with the new file system is somewhat better and almost makes scanning issues a thing of the past but it still has it's initialization issues as reported earlier on the post. The progress bar is such a relief but you'll definitively complain about gapless in this version. I listen to Trance with 1.2.6 and to be honest I prefer the transition, in majority of EDM set transitions xfading is a common technique and really find the transition rather smooth. But it's me and I certainly prefer cross fading than one second transition delay that truly annoys me.
