    If there´s one disadvantage of mp3 it´s that its short block window size is too big, leading to smeared transients on occasion. This will happen with low as well as high bitrates. http://www.mp3-tech.org/content/?mp3%20limitations
     
    AAC or WMA completely avoid this in comparison. But I´ve yet to manage to encode to working AAC (the X3 somehow ignores my encodes) so I´ve opted for WMA Professional for the time being. Secondly, the FiiO doesn´t decode mp3 or aac with 32 bit floating point, despite the fact that this would be easily possible.

    The sound quality we today have is comparable to the early wax cylinders. And I´m not even cynical here.

    Do they have support issues for the X5 already? D:

    May be why I've never like MP3 as much as the others. People get so caught up in frequency when Music is more about time. Something our ears are remarkably sensitive to.

    Hmm, if you don't want to format the card, try stuffing it in the X3, hit "Update Lib" in system settings to update the media database and see if X3 finds your music?
     
    ... if it doesn't, copy the music off the SD card, format the card using the X3 (function available on new 2.05 firmware) and copy the music back into the card and try again?

    Hi!
     
    Besides the idea that HiRes audio files are nonsense for end users, according to Xiph.org, what you feel about wav vs flac could not be entirely placebo. And maybe it has nothing to do with bigger resolution increasing your hearing perception.
     
    I saw a TV article long time ago, here in Brazil, about differences between printed photographs of different resolution taken from not professional grade digital cameras, just the common ones, but of good models from leading companies. Now a brief pause to human perception and practical use of photos. I know head-fi is a music website, so give some trust.
     
    The common sense (at least for those who holds some mature knolege about photography) is that,  above 4 mega pixels, no one can tell any differences on identical printed photos ranging from 10X15 cm up to 24X30 cm (which are common photo printing sizes) and anything above 8 megapixels is only designated to studios professionals, who will manipulate tiny details on the images, or for billboard printing, where pixels are really going to pop up, but which is not the case of 99,98% of end users of digital cameras.
     
    Back to the article, besides it wasn't performed on scientific basis, nor it used a so big volunteer universe, it was lead avoiding placebo issues, and it was IMO a serious and a conclusive small survey. People was asked to tell which photograph looked better from the other identical but in different resolution. They didn’t know which one. The photos was taken in 8Mpx and in 12Mpx and printed in very big sizes (I believe they were 24X30 cm). Surprisingly, the majority of the volunteers did found the 8Mpx ones better than the 12Mpx ones. What the heck!
     
    The explanation given by specialists was that in higher (actually the biggest for the models) resolution the CCDs ran super heating, creating noise on the captured images due to complex imaging processing load on the processor and thus demanding extra power, thus creating extra heating. Though it is a safe operational condition to the equipment, it is not totaly inoffensive to the final result.
     
    Back again to the thread, the complex process involved in decompressing a big flac file into a decompressed PCM playback (which is a wav file) maybe creates some unwanted and undetected and unavoidable noise to the output that goes to the amp. It’s not rocket science, just my interpretation of something totally related.

    You could call anything no longer tangible placebo. Fact or fiction. Doesn't make it so.
     
    Listening to music is not photography and includes time constants with dimension contrasts as well. That's like comparing smell to touch. Your ear also works over many more 'octaves' than your vision with much less retention or need of interpolation. I agree with your vision assessment and still have a 768p Plasma that looks great from 12 feet but it would be easy for me to show you the benefit of HiDef audio in a proper system. Whether redbook vs HiDef the weakest link in an on the go DAP is another issue and probably not for here so maybe we should get back on topic to the X3.

    32gb cards should already be fat32. Maybe he should run a disk check on his PC to make sure it's genuine.

    That was a highly polite way to end a not even started argument. But, no.
    I seems that you are a least mislead, not to say wrong, with the "less need of interpolation", just because the signal was aready interpolated by the digital to analog coverter. And if you mean by "proper system" some $100k equipment playing a clicking LP, I'd only say you're a nostalgic guy who loves big cumbersome discs. And, as you've already said, if this thread is about portable DAPs, so your expensive gear will not fit the point for 90% of people in this post, nor you can carry it around. Furthermore, even being a very high fidelity equipment, and I'm not saying the opposite, when it comes to human hearing, it will not help you with hires audio files against 16/44, unless you´re able to beat Montgomery's article on Xiph.org. Or maybe I should consider you're not human...
    Oh, if it's not probably for here, just link us to some more "apropriate place". And, don't worry about complex words: as I'm electronics technician, I'm able to understand your explanation.

    BTW guys, latest transfer to my X3 seems to be working pretty well. No corrupted files this time.

    For anyone else witnessing the issues I was: Format the X3 using internal. Plug into windows and let it scan+fix, THEN do your file transfer. I got a 3.5mb transfer rate this time.

    Also, i'll be investing in a card reader as soon as this paycheck rolls through. Fiio, I think for the X5 it would be a good idea to make it transfer very fast, like 12MB/s is a fairly acceptable/normal rate. And maybe consider something like NTFS support.

    Interpolation was in reference to how your brain responds to particular stimuli. Nothing to do with codecs. I could easily and blind differentiate custom dithers at 24/192 and different bit rates with the same dither on an AK120 (JH13s) with somebody else controlling the device so for me, proper system only means a good one and not necessarily expensive but expensive is always relative. Easily perceived in a proper home setup at $3k or so. I'm happy for your technical prowess and that you can read but I think Montgomery's wrong about his premise, his math and measures are correct. I'll rely on my own observations. I have some 40 plus years of experience of tech and recording as well. We can agree to disagree and leave it at that. The site actually has rules about this and wants all these discussions in the sound science forum so as to not diminish product threads by zealots on either side of this argument. That is the "appropriate place" and you can be just as abrasive there if you care to. Mods frown on this in equipment forums and your tone in general. Please use this info wisely and welcome to a friendly community.

    To JamesFiiO & Joe Bloggs:
     
    I want to ask again for 32 bit floating point decoding of mp3 & aac.
     
    Activating it will be as easy as flipping a switch since this option is already included in both formats.
     
    Remember: both formats store with 32 bit floating point internally.
     
    FiiO wouldn´t be alone should they activate it... here´s a link to a post in the jRiver forum:
    http://yabb.jriver.com/interact/index.php?topic=63691.0
     
    and here´s a link where Grammy winning mastering engineer Bob Katz says that it´s vital for perfect sound:
    http://yabb.jriver.com/interact/index.php?topic=76912.msg521299#msg521299
     
    and here´s the link to Apples 'Mastered for iTunes' initiative:
    http://www.apple.com/itunes/mastered-for-itunes/docs/mastered_for_itunes.pdf
     
    As you can read for yourself, Apple recommends sending them high definition material; they know very well that aac is perfectly able to encode material with high bit-depth. Right now however, the FiiO X3 is unable to play back those 'Mastered for iTunes' releases in high quality.

    There are many many factors leading to differences in quality between different camera sensors.
    There have been countless arguments over the years that less is better when it comes to megapixels, yet pixel count on cameras have continued to increase and quality has continued to increase as well.  Some sources of sensor noise actually decrease as you increase the pixel density while fill factor (the % of sensor area that is actually sensitive to light) tends to decrease as you increase pixel density, UNLESS technology has advanced to improve fill factor.  In the end it's all a tradeoff, but the optimal pixel density for cameras has increased as technology advanced.
     
    Back to audio, one could argue that decoding compressed lossless places additional strain on the CPU which might cause electrical interference with the DAC section, but one could equally argue that playing back uncompressed lossless places additional strain on the disk I/O section which might also cause electrical interference with the DAC section.  But in reality, the X3 DAC circuits are too well shielded for this sort of thing [​IMG]

    You mean if it came new out of the packaging?  I was assuming that he had an existing card full of music that he wanted to use without reformatting.  That could be formatted in any number of ways.
     
  15. goodvibes
    Yes I did. Nothing he did to the card should have changed that other than actively doing so. If the card never worked, I would think he's either got unsupported music formats or a defective/counterfeit card. The reason I said check the disk was to verify that it actually could hold 28gb or so.
     
    Simple formatting and giving it another go 1st wouldn't hurt. [​IMG]
