I see this talk about android Libraries and all ffmpeg libraries being removed, if ffmpeg isn't being used to decode the sound what is? And if the libraries are in place but not being used then it's not effecting the sound.. Can someone explain to me what this is supposed to mean?

Removing ffmpeg is the reason why most of DOC's FW don't support mp3 and some other audio formats, it is also the reason why Dima's FW has the option to choose weather you use them or not.
 
The ffmpeg libraries in 1.5.0 are better than those from the previous versions, but they still have minor negative effect on detail, micro-detail, sound stage and some macro level dynamics thus when you listen lossless formats they have a degrading effect.
 
Cheers!

  I really enjoy the fact that all android libraries and all ffmpeg libraries are removed. 

Fairly but not quite. Only soundfx android libraries are removed (lib/soundfx). Ffmpeg remained in place. FFmpeg is used for mp3 decoding and "gapless" feature but it does sound to be more flat.
FFmpeg is used by mango player. When you choose "Lossless only" in SU settings then a mango player load another config without FFmpeg/EQ component/gapless/etc. Only Lossless decoders are used in "Lossless only" config.
 

  Dmitry, thanks for your efforts! I really enjoy the fact that all android libraries and all ffmpeg libraries are removed. This gives more neutral and balanced sound in the bass and the mids also a better sound stage, still I would prefer darker treble - even Diana Krall in 24/192 has quite sibilant "Ssss".

Do you use "Lossless only"? Not sure, I hasn't any sibilant. But sound is light, yep.
 

  First question - is this purely due to the hardware/Wolfson or is it due to the Mango? 

It's the question for iBasso engineers I think, it's Wolfson.

Second question is there any way to make the treble more rolled-off/darker without using the awful iBasso EQ? Perhaps if I filter/cut the delta-sigma high frequency noise? How do I do that? I know you have left HIGH irr bandwidth by default which basically disables the filter is that correct?

You can change irr bandwidth on the "settings" screen. By default is enabled to HIGH(more details/noise?).
 

I would love a combination of the natural bass and great detail in the mids that your FW has and the laid back treble from DOC's DX90 PORT DARK EDITION

I think, you should try some hardware mod Seems like I will try do it for my player. Any software manipulations are bad for sound.
 

Thanks and keep up the good effort - looking froward to version 2 with more settings and even higher usability comfort!

Sure

See above.

So what codecs are being used to decode the lossless files?

Just clarify, not only ffmpeg but some other components like EQ(does not matter disabled or not) have minor negative effects. What's why "Lossless only" config uses only lossless decoders. If "lossless" config is used SQ == SQ without mango player(I checked it with some WAV console player )

Decoders are written by iBasso engineers. Single decoder for FLAC, single for APE, DTS, etc.

I should have guessed that in besides cutting android's lib/soundfx and ffmpeg libs(as before I am talking about "lossless only" config) you also did remove the EQ component from the "SW tract" too!
 
Now I am going to try to make SU 1.2.1 as dark as possible (without altering the sound of course)! So are there more things to do besides these bellow?
1. ussing lossless only - option checked in the "settings" menu
2. using iir_bandwidth=0 - irr bandwidth unchecked in the "settings" menu
3. ?? using Sharp Roll-off DF ??
 
 
UPDATE: I tried the three points above - the treble didn't get any darker and I didn't notice any difference with iir_bandwith=0 and =1 so I guess I'll stick to your purist approach and use both "lossless only" and iir_bandwith=1
 
That leaves only one question - does the Slow Roll-off DF actually have any effect on the Wolfson DAC? Some claim that it only has effect on the ESS DACs in the DX90 and no effect on the Wolfson given it's technical specifications!
 
 
Cheers!

So then why not just tell ffmpeg not to be used as the decode for FLAC, etc.. ?

   No way

Effect should be.. maybe a little bit psychological Anyway,  for me "Sharp" - "clear/brighter", "Slow" is more "smooth"(not sure in using worlds ). Check it using high volume, watch for the treble.

Good question. I think this one is the bug. I already posted bug report to iBasso about two weeks ago. No answer.
 
Seems like this is implementation problem.  Audio stream passes all enabled components, nevermind FLAC or MP3 is decoded. But it's just a guess

Ahhh okay thanks for taking the time to explain.

I'm still trying to figure out this wallpaper thing.  What is it I need to do?  I named the file correctly and as far as I know the right size specs.  What am I missing?

Check its dpi. If it's too high (maybe >600 dpi) it may not show up.

 

[zzzzero]

I'm not sure but this was one of the ones uploaded on this forum. I'll have to double check.. If that's not the issue could there be anything else?

Sound Unlocked 1.2.2. Tiny update.
 
iBasso developers solved CUE support problem with the new DX90 firmware. But both platforms(DX50/DX90) use identical music application - Mango Player, so the problem solved for us too.
 
Changes:
  Fresh Mango player.
 
Don't forget about "Factory reset" and "Rescan library"!

Thanks! I just updated to 1.2.1 a minute before you posted this... 

 
And just to clearify, are the selections simply verified in settings screen by sliding from locked to unlocked, which reboots the player?
Do you have a site where you keep the latest version and some log of changes? This would help always finding the needed information in case some post in here goes unnoticed.
Thanks for the great work for making our players even better!
