Got my dx90 last week and been trying out all my files. And as most people say, the
gapless is somewhat buggy on some files. So i did some experiments. Ill just make this post straight and brief. And
PLEASE CORRECT ME if it is posted somewhere, proven wrong, I have a faulty hardware and/or already solved. Disclaimer: English is not my language so please be gentle.
Defaults
Firmware = 2.1 lurker0's - 2nd international version (the stable cpu high performance)
Burn in = 100+
GAPLESS ALWAYS ON
Fresh from factory defaults
All done on internal memory NO SD card
Albums used and initial transition. 1st track and 2nd track are only used for reference. (That epic intros)
Album: Linkin Park - Hybrid Theory = album
A
Details: (24/48) FLAC individual tracks (no cue sheet)
Initial Transition: Flawless transition from 1 to 2.
Album: Iced Earth - The Glorious Burden = album
B
Details: 320 CBR MP3 with M3U
Initial Transition: 1-2 sec transition
Album: Pathfinder - Beyond the Space, Beyond the Time = album
C
Details: VBR Mp3 with M3U
Initial Transition: 5-1.5 sec transition
1st thing I do was REMOVE ALL TAG from MP3 including image.
album
B: Click/Pop (100-200 ms) on transition.
album
C: Click/Pop (100-200 ms) on transition.
The thing is that album
B have
multiple tagging so removing this improve the transition greatly.
2nd thing was to downgrade the FLAC to MP3 320
album
A (no tag): small pause below 100 ms on transition.
3rd thing was to convert all albums to FLAC including album A
album
A: Flawless transition
album
B: Flawless transition with a somewhat faint tick (barely noticeable).
album
C: Flawless transition
TL
R???
Conclusion
- Playback gap on gapless mode is very big when MP3s have tagging issues.
- Clean MP3 (no tag) still has noticeable transition on playback.
- If still irritated, convert your lossy into lossless. Will work about 90%? (lols)
This is just the things i did to try to find what's the problem. And it didn't solved anything, only raises more questions. I am in no way have technical know how on this DAP so if anyone got answers. Again, i can to delete my post if anyone can correct me or have solutions. Thanks guys.
