there will have small click sound between two sound track if they are not the same sample rate or bit depth. it can be solved cause the DAC chip need to reset to another clock frequency. 

 

of course, we will see whether it happened at the same sample rate

 

I can confirm It happens with tracks of the same sampling rate (actually from the same album, too).

If you look back many many pages you will see me complain about OGG.

I gave up to be honest.

 

Swapped to FLAC. It is a solution for me but I do feel a little annoyed that it can't do what it says on the box, principle and all...
Same goes for MP3.

thanks for your report, we will see what happened whether we can fix it in the future.

we are working in the ogg. and what I mean is that the best way is convert the CD to FLAC or WAV or even AAC , will better than mp3. 

 

not change from mp3 to aac or flac, it makes not sense to do that .

James, this is not acceptable. I have been a huge supporter of this product. I have hundreds of dollars in Amazon MP3s and re-encoding is not an option. Just a few posts back, I said "Don't worry they'll fix it". 

Please don't make me into a liar. As far as MP3 SQ, many tests have shown it to be as capable of good sound as any lossy format.

Will you commit to fix MP3 decoding? Will the X5 have the same issue? If so I will be unlikely to pay to upgrade to one.

Coming from a application support background, I agree with other posters that fixing existing issues is preferable to adding features.

it is different, for ogg, there are bugs should be fixed. but for other loss music format , includes aac/wma/mp3, all have room to be improved. but the fact is mp3 is the worst format compare with aac/wma.

Yes it happen to mine too. And it always pop when I just started the unit and played first flac track, I think it may happen on WAv as well.

We can argue the fine details about which format is best (and there is huge amounts of data available - at high bit rates there is relatively little difference amongst lossy codecs - here is one of many articles - the advantages of AAC mainly come in at lower bitrates) but the fact remains that your MP3 decoding has readily measurable issues that have nothing to do with the format itself.

As mentioned if you have purchased MP3 music other codecs are not an option!

Always before, when an issue has been identified you have come forward and said "Yes we are working on it, will be fixed in future firmware". Why is this so different?

1. i have searched the Internet and can find little that compares the x3 with the rockboxed classic ipod either 5.5g or 6g. I want to know if the x3 will give better sound on 16/44 lossless files from 1930-60's jazz/blues some of which are not recorded

I have ipod suffle, iPod Classic 120gb, iPod nano 4g, iPhone 3GS, iPhone 4, iPhone 5.
From the series of apple product I have, what I notice is worse sound goes on suffle, 2nd worse is the classic, then sound gets better and better from iPhone 3GS to 5. iPhone 5 is the best sounding device I had from apple so far.

Despite the super good music app on ios 7, but I'm still looking for a device with better sound and capable to store more music than my 16gb iPhone 5, then I chose x3.

First thing I test is transfer some 320kbps mp3 that I had in iPhone 5 to x3, then I run with klipsch s4 II by playing same track switching between both devices and I can notice x3 has much much clearer vocal and stereo effect, iPhone 5 just give me a little bit muffled sound, not only that but bass and mid also more accurate and shine on x3. I'm not pro audiophile and won't use what professional term to describe like those pro reviewer but when you start listening on x3, you will love the sound and keep you reminded to bring that unit everyday to work and you will think to turn it on to listen to your favourite everyday.

Now I transfer all my itune songs to musicbee (this is Free and way better than media monkey) and use the x3 and dac to listen to all these favors songs.

Then in my car I use it as line out the hu and i is the first time I heard such clear audio out from this cheap ICE hehe

Definitely a worth buy where you will use it every moment everywhere.

Don't freak out just yet, boys. While the mp3 decoding doesn't seem to be perfect, I honestly only notice it on James's reported mp3 files but not on any of my own mp3 files. Here are some of the X3 (v2.1) RMAA result I did yesterday on wav (original), flac (xrecode II encoded), aac (iTune encoded) and mp3 (Lame encoded). Lossy are definitely not as good as the lossless but I don't think mp3 is much worst than aac. As I have said before, all the lossy have their own problem. If you haven't heard any significant distortion in your own music, don't worry too much.

This is kind of interesting. I do not own a fiio X3 or neither do I intend to. But is it possible that different versions/releases of the lame mp3 encoder creates different results/lossy versions that are more or less react differently with the X3? Or does some of the lame mp3 encoder version perform/measure/sound better than others and/or better matched with certain processors/chips, well I do believe that's a possibility but it would need some extensive testing to check this out. Maybe ClioOS or someone else will one day find the time to challenge this? :-)

I've been asked to re-share the noisy mp3 file in question, so here are the new links:

 

mp3

flac (transcoded from mp3)

- Different version of the lame mp3 encoder produce encodes differing slightly in quality (for better or worse)

- lame mp3 are always encoded the same way, whether it´s on AMD, Intel, any MS Windows, Apple OS or Linux -> lame mp3 is designed to be completely platform independent

- the only difference between the platforms is encoding speed (depending on CPU speed & efficiency of the OS)

- until recently I wasn´t aware of decoding differerences but they existed roughly ten years ago with certain software based decoders

ClieOS, would you mind to try re-encoding my flac file to mp3 and see if you can produce an mp3 version that sounds less noisy on the X3?

 

 

I've noticed this issue on several (mostly classical) tracks, granted all rather quiet recordings, but they all sound cleaner on my SGS3 smartphone. I'm also pretty sure the files in question came from different sources and I'll see whether I can find another example among my Amazon mp3 downloads.

 

From my experience, those who only listen to pop and rock will be unlikely to notice audible artifacts, but those who listen to quiet genres like classical or ambient might very well be affected.

I have to ask: how did you encode the aac? You used the iTunes encoder just like me yet your measurements show distortions I haven´t seen yet coming from aac in combination with the FiiO. The results for mp3 are a match. But what was your datarate? Mine was 320 kBit/s for every codec (except wma).
