Sean, thanks for Your answer. Please don't feel bad about my post, it is more argument in discussion then request to Slimdevices. I overreacted after provocation( not from slimdevices).

Re: [SlimDevices: Audiophiles] Posible bug in built-in MP3 decoder - please verify
Some notes have been added to this bug. Basically it is the difference in precision between MAD's portable fixed-point multiplier and the x86-optimized version. There is possibly a better multiply routine we could be using which would get closer to the X86 version. Nenad, please relax. This doesn't need to be the kind of confrontation that you're making it. I have already apologized for the delay in getting to this bug. If it turns out that we need to revise our marketing copy based on what we learn, then we'll do that. For now I am trying to determine if the accuracy can be improved to match the x86 version.

The replay gain problem is if you happen to have had Itunes do it's soundcheck (which I was using for my 2 Ipods) then for some unknown reason they decided that the sb should add track gain and soundcheck together.

Re: [SlimDevices: Audiophiles] Posible bug in built-in MP3 decoder - please verify
Well I had to wind my system up gain 99 (out of 100) to hear the -75dB one...at which point I could hear what was left of the music and the artefacts. But I'm running the system so loud (with over 500 watts of active amplification) that normal music would be at the pain barrier!. Anyway - I stand by my point. In normal usage i can't see how this would ever get heard. How did you manage to hear it? I can only imagine you were listening on headphones with the gain wide open to a track recorded at a very low level? Anyway as I keep saying, I converted the files to FLAC (using Switch Plus) and the artefacts disappeared. So there is a perfect workaround for the one file out of 100,000 that might have this issue...

Re: [SlimDevices: Audiophiles] Posible bug in built-in MP3 decoder - please verify
I've listened and I'm afraid your samples just prove the previous point that the artefacts are swamped by the noise floor of a typical non-audiophile sound system. Yes I can hear the artefacts very clearly when I turn up my amp way beyond where I would normally listen. But at normal listening levels I can't hear the -75dB track at all above the normal noise from my amp and I can barely hear the -45dB track let alone the artefacts. Most of my music is in MP3 ~200kbps VBR at the moment and I have never heard these artefacts in normal listening. They are quite distinctive when you can hear them, but I never have heard them. I'm guessing that if you listened to a lot of classical music with very quiet but not silent sections then you would have more chance of hearing it in real life, but you'd have to have a much quieter amp than mine for it to be noticable. The bug should obviously be fixed, but it is unlikely that many people are actually suffering because of it. I'm moving to FLAC now anyway, I don't really see a good reason for sticking with MP3 nowadays (though I still have to generate MP3s for my empeg). I now SC has all sorts of transcoding options, though typically to transcode to MP3. Is it possible to get it to transcode from MP3 to FLAC ? At least then those few people who are really affected (MP3 users, with very good amps and music with quiet passages) could have an easy work-around without having to convert all their MP3s. -- andynormancx Yes, it will.

Re: [SlimDevices: Audiophiles] Posible bug in built-in MP3 decoder - please verify
For the record, my carefully ripped MP3 files sound awesome on the SB, I have not encountered the described issue and kind of doubt I would encounter a scenario like that. Most people, upon playing good burn-in and test CDs (such as Sheffleid Labs) discover that their systems have frequency areas that are non-linear, and sometimes even extremely good speakers show borderline resonance during a slow sweep. So while at this point it seems established the SB is not entirely linear in its frequency response, I wonder if it's really such a scandal given its marginal significance and the fact the rest of the music reproduction chain is bound to also show occasional non-linear response. -- pablolie pablolie's Profile: http://forums.slimdevices.com/member.php?userid=3816 View this thread: http://forums.slimdevices.com/showthread.php?t=40409 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

All my favorite, well recorded albums are FLACs. That represents about 10% of a collection that consists of about 2,500. I also record them to 320k MP3s for convenience, and keep both - FLAC for listening, MP3 for portability and universal compatibility. Most commercial or poorly recorded music I simply converted to MP3, 256k or 320k (quite whimsically), because it is more than good enough and because of convenience and compatibility. I love FLAC - my issue with it is compatibility across platforms (portable player, car etc). So my using MP3 does not mean I don't enjoy listening to music with high quality - it just means I am convinced I can take the convenience factor of the SB one step further without a penalty in sound for a lot of recorded music. Case in point, and a discussion I had last night with a fellow audiophile in San Francisco after going to the Return To Forever concert: we're there live and there is less staging than if I'd played their music as a 160k MP3 on my home system. Really. No matter, we enjoyed the concert (even though of course they had their self indulgent moments, and Chic Corea shouldn't be chewing gum when talking to an audience, imho). But it just comes to show we sometimes get a tad overboard with this obsession on staging and such. Most recordings have no staging whatsoever, so trying to preserve that makes little sense. And with the loudness wars sadly a lot of resolution has been sacrificed. Many things make many recordings perfectly happy 256k MP#s that no one could tell apart from the FLAC encoded equivalent. But then again, I don't dispute that on well-recorded stuff the difference can be baffling. -- pablolie pablolie's Profile: http://forums.slimdevices.com/member.php?userid=3816 View this thread: http://forums.slimdevices.com/showthread.php?t=40409 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Robin (and many others) points out this bug doesn't affect many people because: - Audiophiles don't listen to lossless - Average Joe dont need high quality So, conclusion is, high quality mp3 playback is not important to most users, and this bug have low priority. BUT, at the same time, all slimdevices (Squeeze, duet, transporter) have these statements in specification (my caps and bold): Compressed formats (MP3, AAC, Ogg Vorbis, MP2, MusePack, WMA) MPEG decoding uses MAD software, *WIDELY REGARDED AS THE MOST ACCURATE*, most compatible MP3 decoder. *HIGH ACCURACY 24-BIT SYNTHESIS* Supports all MP3 data rates and sample rates, including VBR I understand these statements as advertising of high quality mp3 playback capability. So, - When you need to make selling point, high quality mp3 playback capability *IS IMPORTANT* and emphasized in specification. - When you need to fix bugs, high quality mp3 playback capability *IS NOT SO IMPORTANT* and bugs have low priority. In my opinion, because of bug, slimdevices mp3 playback quality is bellow average, because *accuracy of decoder(because of bug) is about 10-12 correct bits* (my estimation - needs testing but I believe it is true). Statements in specification gave *false impression of high quality mp3 playback capability*, when implementation quality, because of bug, is *bellow average*. To make conclusion, *IF SLIMDEVICES IS FAIR AND HONEST COMPANY*, they will *remove false claims* of high quality mp3 playback from specification and other advertising material * until this bug is fixed *( it is now open more then six months).

Nenad, Calm down. There is a bug - I believe that has been confirmed (I've not investigated myself). However, as many people keep pointing out, it really doesn't affect many people - you seem to be the only one who has reported it. And, for those that it does affect, there is a perfectly satisfactory work-around. There are other bugs that are more severe and that affect many more people (wireless connection issues, etc). You can get an idea of the priority a bug is likely to receive by multiplying the number of people affected (impact) by the severity, and possibly add a factor taking into account how much effort a fix is likely to take (resource), i.e.: priority = impact * severity / resource In your case: Impact: low Severity: low Resource: high So, priority = low * low / high = v. low This isn't going to get priority over the many other things that SD are working on at the moment, some of which you are not aware of. You can bleat on here and anywhere you choose, but it ain't gonna change a thing.

If we're talking about people on this audiophile forum, and so people using transporters and SB3 in good hifi systems, I would guess that the vast majority will be using lossless most of the time. My guess is that people are only using MP3 because they have some downloads or for some reason don't want to buy more disk space or also use the same files on portable players. Those who do have large MP3 collections do not in the main appear to have noticed any problem - I didn't on any of my MP3 downloads. I have never seen it discussed in any other thread. Clearly it's not audible to most MP3 users or there would be a huge outcry. I really do suggest you get this into perspective.

Yeah, I have to concur here. I use FLAC whenever possible, but some music is only available to me in mp3 (ie exclusive downloads from emusic). I accept that it won't sound as good as my FLAC files, but I'd like it to sound as good as possible. I am not saying that SD has done a poor job in prioritizing this bug -- I don't doubt there are higher priority problems that need addressing. But I don't think people should trivialize or dismiss this bug just because it affects mp3 playback, and I do hope it gets fixed.

Problem solved. The fact that the SB doesn't do as good a job as it should is secondary to the core fact that the source data is already compromised. You're never going to get as good an experience as you could do. To me it's like buying a compact hifi system and discovering that the cassette tape deck doesn't work as well as it could. Do I bother with complaining to the manufacturer, or just go play CDs instead? I know it should play the tapes better, but even if it did, they are still an inferior experience.

Sikahr, Not every bug can be fixed for every software release. Sometimes they are retargeted for future releases (sometimes specific releases, sometimes not) based on a variety of factors, including number of customers affected, severity (eg catch fire vs inconvenience), estimated time and resources required to fix, number of other bugs ahead of it, and so on. I'm sorry that we do not expect to resolve your bug for 7.1, but there are many other bugs that _have_ been fixed. At some point we schedule a release to get those out, and anything still open at that point remains open for a future release. If you want to gain more perspective on the process, I would recommend looking at other bugs in the database, both open and closed, to see how it works. I realize your frustration, but unfortunately not everything can be done as quickly as we would prefer. -- seanadams seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=40409 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Posible bug in built-in MP3 decoder - please verify
I placed my vote on the bug ! and this bug: (http://bugs.slimdevices.com/show_bug.cgi?id=5119) Why ? while i'm dont use much mp3, or volume control, replay gain or normalization etc.I prefer flac to a digital input in my surround processor, where further processing takes place (another argument for lossles format). I'm in the process of replacing all mp3's with flac btw. I do think any soundquality related issue should be investigated asap, these are the 2 i know off how many more are loose ??? Sound quality is the essence off any good audio device. Dodads features and bling takes second place. Issues like these 2 shows that quality control could improve, what I'm saying is, is it only the mp3 encoder that have bug's ? I'm thinking like this: The real issue is not mp3 playback, it is QC and How that is implemented at slim/logitech. It could be that it is only a coincidence that it is the mp3 encoder that is broken this time ? Afiak the SB3 has the following built in encoders: FLAC,WAV,AIFF,WMA,OGG,MP3 are all these tested every firmware uppdate ?

I have serious reservations with paying good money for lossy music - its bad enough that the source material is so badly compromised with the 'loudness wars'. For now I've compromised by only purchasing drm-free lossy formats (emusic). And there is a limited amount I can buy in flac format through zunior.com. Some of the major labels have recently started offering drm-free, hopefully it won't be much longer before they offer flac (or some other open-source lossless).

sikahr;248302 Wrote: > Do You hear any differences between properly coded mp3 and lossless on > normal listening levels. > > I think for 99.% of population answer is no. IMHO, the answer is a little more complex than that. I believe that many who do not hear a difference could, but do not because: 1. They do not know what to listen for. Most could learn, and they might then understand some of the subliminal influences that lossy encoding most likely has on just about all listeners. 2. The source material has so many flaws that source flaws make it harder, especially for untrained listeners, to pick out the coding artifacts. Many popular recordings have relatively high distortion; since that flaw is so obvious its easy to focus on it and miss the more subtle CODEC flaws. 3. The playback system has flaws that tend to overshadow the CODEC flaws. Poor frequency response, high distortion, etc. Back when I started encoding my CDs to the hard drive, I considered 320 kbps MP3 and high-bitrate AAC, but I ultimately chose FLAC. Although I did some listening to all formats and found the differences to be subtle, maybe even imagined sometimes, I understand that my playback system will change with time, as well as my critical listening abilities, so I decided not to base a decision for a lossy format on my current system, listening abilities and a small sampling of source material. Hard drive space has been getting progressively more inexpensive as my collection grows, so it was not a hard decision for me to chose FLAC lossless. And another advantage of FLAC is that I'm not at the mercy of Microsoft (WMA lossless) or Apple (ALAC). -- Timothy Stockman Timothy Stockman's Profile: http://forums.slimdevices.com/member.php?userid=8867 View this thread: http://forums.slimdevices.com/showthread.php?t=40409 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Possibly, possibly not. But even *if* not now, I may improve something in my system which might reveal differences in the future. Cheap hard disc space is a very small price to pay for input signal integrity. Just as I used to look after my vinyl, I want to make sure that my system starts with the best signal possible. GIGO. In any case, even with the best will and intention in the world, mucking about with digital files in this way can and does introduce audible distortion, even if it is not intentional.

I have a very serious stereo, I've paid tens of thousands of dollars to make sure it delivers every possible bit of quality. Disks are very cheap, 500 GB costs under $300. I have zero interest in reducing file size by 30% and then lose any quality. YMMV, etc. but most folks don't care about MP3 quality. If you accept the known loss of quality, then you may chose otherwise. Its just not worth it to me. And I do not agree with your "zero quality reduction" argument. The facts don't back that up. I'll agree that you can't tell the difference, or that its not important to you.

Imperceptible maybe, but never zero by definition. That fact bothers a great many of us, enough to warrant spending a measly $100 on a 500 GB hard drive. Perhaps I'm obsessive-compulsive, but the very idea that lurking among my music collection would be one "killer" MP3 where I could hear audible artifacts would drive me nuts. I'd have to listen to every track intently, not enjoying the music but listening for errors. And if I found one, are there more?

Yes, I know it for a fact. FLAC is lossless. By design and implementation. MP3 is lossy. It throws away signal that it thinks is not important. This lost information can never be recovered. Take a wav file, compress it with flac, uncompress it to a copy, run diff on the original and copy. They are the same. A double blind test is not needed. All a double blind test shows is that the folks could not reliably tell a difference through their equipment. Double blind testing is how you quantify subjecting things when you can't measure them directly.

Use flac - it's better than mp3 anyway. 3. Stop whining. Most people here don't care about this issue.

Re: [SlimDevices: Audiophiles] Posible bug in built-in MP3 decoder - please verify
update: i just did some reading of the entire thread (9 pages!?) and noticed new (music!) test samples from dcolak. i downloadad and listened to them and i am SHOCKED. i can hear a SEVERE background noise, which is modulated by the music. my GF can hear it too and she does not have audiophile ears. >sample 1: clean+clear >sample 2: VERY audible noise floor (like a hiss), modulated by the music >sample 3: same as 2, but also seems to include clicks (may be due to the sampler/ripper you used) >sample 4: clean+clear this is more or less the same for all music pieces. i found especially "aint no sunshine" terrible. at around ~8sec in to the song, she sings "..its not warm...", where the artifact is fully obvious. for good measure, i tested the MP3 on my iRiver player with headphones and there were no audible artifacts, so the file seems to be OK. we have never noticed this before and (as i mentioned above) we have A LOT of MP3s, many of them at fairly high bitrates. now that i knew what to look for, i tried to find MP3s in our collection which show the same behaviour - and found some! however: i can only hear the artifact if the track is quiet and the volume is turned WAY up. but honestly: since i didnt go through the trouble of listening to the originals on CD i am not even sure if i am autosuggesting to myself or if the hiss is in the original recording. only the fact that the noise is clearly modulated suggests to me that i am hearing the artifact you guys discovered. thanks for the workaround, sikahr. i am not sure if that is an option for us, since transcoding means no more FFW/REW, and my GF needs to have that. she already resents the fact that i prefer vorbis for my CDs which does not allow FFW/REW either. ;-) -- dcote dcote's Profile: http://forums.slimdevices.com/member.php?userid=9701 View this thread: http://forums.slimdevices.com/showthread.php?t=40409 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Posible bug in built-in MP3 decoder - please verify
amazing how much attraction this thread is getting for the fact that "nobody" is interested in MP3 format. ;-) personally, i appreciate these guy's efforts, because my GF is not technically savvy enough to rip her music to any other format than MP3. that means that half our collection (~3000 songs) is in MP3 - for me that means it is a majorly important format. because of this, i have voted for the bug. i agree, it is great to see that the people INSIDE slimdevices take this feedback seriously. in this day and age where products are becoming more and more similar, customer service and acknowledgement is a BIG differentiator. please logitech/slimdevices: keep it that way! -- dcote dcote's Profile: http://forums.slimdevices.com/member.php?userid=9701 View this thread: http://forums.slimdevices.com/showthread.php?t=40409 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
