Re: [SlimDevices: Audiophiles] Cracking between tracks
Hmm. Well, again, there is nothing special about track transitions as far as the s/pdif is concerned. No information about a track change is transmitted, nor is there any interruption of the signal or change in the out-of-band data. (I am only speaking of SB3/TP here - a CD player will at least change the Q-subcode data) The only "special" thing that might be more likely to happen during a track transition than elsewhere is that the signal could be composed of digital silence (all zeroes), depending on the CD. This causes the s/pdif signal to have the fewest possible number of transitions in each frame, as opposed to any other audio signal which will have a random and roughly equal distribution. A buggy s/pdif receiver may have trouble locking on to the signal, but even if that were the case, I wouldn't expect it to cause crackling. Rather, it would cause significant dropouts which might sound like the beginning of the next track being cut off. I have never actually heard of that happening, but it's plausible. The other thing that can happen in the presence of digital silence is that a DAC could conceivably trigger a hardware muting circuit. Some DAC chips even have dedicated output pins to signal all zeroes, for this purpose. However IMHO that would be a rather stupid thing to do for a valid, all zeroes signal. You would only want to do that if the signal were no carrier at all. So really I don't know what's going on in your system. If you get it into a state again where you can reproduce the problem, you might try concatenating two tracks together into a single file and playing that. If you still get the crackling between the tracks then it could be a data sensitive issue. -- seanadams seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=37264 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Cracking between tracks
I tried a bunch of tests, with unmodified SB3, with a different DAC, with the clock off on the DAC and could not reproduce the problem. Unfortunately (fortunately?), I have been unable to reproduce it with my orignal setup either. It was not as dependable as I thought. I guess I'm out of options for narrowing down the problem for now. However, I'll include a comment for the designer of the RAKK DAC : > We have seen crackling in the gaps before.

[SlimDevices: Audiophiles] Parametric Equalizer?
Hugh at Inguz was kind enough to program in a quasi-parametric EQ function. It seems to me this idea should be included in the core software. Almost everyone has some frequency characteristic they'd like to address and using the parametric is a piece of cake - no special equipment needed. Test tones and an SPL meter - voila! It is fully possible to get near-flat response in less than an hour. Or, dial in a hump or dip to taste. Can this be added to future releases?

Of course with such a dynamically developing system, any printed manual is destined to be out of date before it's even printed. I expect that the Wiki and online documentation will mature and take care of most of this, but the fact that the system is currently pretty geeky and the development decentralized, it's going to be hard to find all the information one might need in one place and clearly organized. I'm sure Logitech will be struggling with this as they go forward in trying to make this appeal more to the typical non-geeky consumer.

A puzzle. Actually, what you're describing does not sound at all like what I'm suggesting is happening here. To be clear, I am not talking about "losing sync" as in the s/pdif receiver is not getting a valid stream. I am talking about data being clocked at the wrong rate into the dac, causing bit errors in the PCM data. The reason I am suggesting that is because the specific mods that Jitterbug made to his hardware would be _expected_ to behave like that if the sync connection were not working. It's basically the same as if you had a DAC in word clock mode, but the source component was in regular (master) mode. You get two different clocks. However they will be close enough in frequency that most of the data gets through, but you get some occasional cracking. Now, maybe this has nothing at all to do with that, in which case it may in fact be the same problem that you experienced. The fact that this happens only at track transitions is (at first glance) INconsistent with the clock-out-of-sync explanation. That's why I'm not entirely confident that's what's happening. The thing is, there is nothing special that happens on our s/pdif output at a track transition. It just pumps data all the time and simply has no notion of tracks changing. -- seanadams seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=37264 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

slimkid;218394 Wrote: > And again. What is the purpose of the manual if it isn't accurate? Of course a manual should be accurate (and as far as I know, every one I have written was at the time it was issued). The critical point you are missing is that the purpose of a manual is to instruct users how to operate a product. It is not for the purpose of enticing purchase. That's what advertising is for. Manufacturers are legally required to deliver what they advertise, but the same legal standard does not apply to user manuals, and never has. Regarding the specific issue of the FF/REW description in the manual, presumably either: a) the manual's author mistakenly assumed that it would function a certain way (often the manual needs to be written before the finished product is ready for testing); or b) the product was originally intended to function the way it is described in the manual, but the engineers were unable to comply, because it turned out to be too difficult, or it would have delayed the release of the product, or other features and functions were deemed to be higher priority, or there's a bug in the firmware, etc. That's why "specifications are subject to change without notice." In either case, the manual should be revised to reflect actual operations. Whether the product should be revised is a business decision of the product management team at the manufacturer, and has nothing to do with what happens to be stated in the user manual. Sean's post that started this thread explained in great detail why the company has not implemented FF/REW the way you and some others would like it to work. Frankly, I'm amazed that the CEO of the company would expend the time and effort to make such a post. I have no doubt that he has other important things he could be doing. But at least it's a sign that he cares enough about his users to explain the situation, even if he can't necessarily please everyone. -- TiredLegs TiredLegs's Profile: http://forums.slimdevices.com/member.php?userid=6201 View this thread: http://forums.slimdevices.com/showthread.php?t=36446 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Well, most of Behringer stuff has consistently bad reviews reporting numerous failures, and its analog stage is said to be just of cheap design and bad parts quality.

This has been discussed before. While it is certainly possible that the act of the SB decompressing the FLAC could change the sound, the bits are the same as WAV once it is decompressed. It seems unlikely that there would be audible differences. Of course, if someone were to consistently identify the difference in a proper blind test, I would have to concede the point. -- jeffmeh jeffmeh's Profile: http://forums.slimdevices.com/member.php?userid=3986 View this thread: http://forums.slimdevices.com/showthread.php?t=37251 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?
Yes, I guess that telling if this method differs from the previous one or not is better. We're really getting into depth of signal detection here, I guess you should even have a calibration run... -- brjann brjann's Profile: http://forums.slimdevices.com/member.php?userid=12214 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I am not sure how to answer with the forum system hence I will cut and paste. 1) Does it happen at the same point in the track every time? The reason when need to know this is to determine whether the problem is due to the Squeezebox being unable to decode a specific portion of the file (as opposed to an intermittent failure). At first you said it was at the same point in the file every time, but then you said you suspected some RF or noise phenomenon, which would be inconsistent with that. ANSWER: This goes back to our earlier discussion. Last night, for example, it (transporter and SB3) I played one CD and it was fine then I started to play another CD (from the 'server')and the problems started again. It seems that when the problems start then it can 'stick' on the same track or carry on at random. It is most curious. 2) Does this happen with all file formats, or just one? This would help identify whether it is a software or hardware issue, and may also help us understand if it's a problem specific to some of the files you are playing. ANSWER:I only use flac. 3) Does it happen on Squeezenetwork as well as Slimserver? This helps identify whether there is something funny going on at your server. ANSWER~: I will check this soon, that is before you get out of bed in the US. 4) Does it happen on both wired and wireless? I didn't ask this earlier because your description was not consistent with buffer underrun behavior. However, in light of all the confusion it would be a very good thing to test. ANSWER: This was, as wrote before, the first thing that I did. I used a crossover RJ45 same problem. 5) Does it happen with all the outputs? If the problem happens on a digital output but not the RCAs then that rules out software issue and point to a problem with player, the cabling, or the receiver. ANSWer: i HAVE TRIED IT WITH DIG, OPTICAL AND ANALOGUE ALL THE SAME (SORRY CAPS LOCK ON) 6) does it happen with different amp/speakers. At first it stopped happening when you changed amplifiers, but
Re: [SlimDevices: Audiophiles] Cracking between tracks
Just guesses, but maybe you could try toggling the 'digital output always on' setting in Player Settings>Audio, or transcoding one of the offending files to FLAC for comparison. -- Skunk Skunk's Profile: http://forums.slimdevices.com/member.php?userid=2685 View this thread: http://forums.slimdevices.com/showthread.php?t=37264 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

However, I think that identifying the source/method is an unnecessary and overcomplicated step. You simply need to repeatedly be able to detect a difference when there is one, and no difference when there isn't. Identifying which is which is not required to prove that the two cases are different, and trying to do it introduces a whole new set of perceptive errors into the experiment. Once you have established a difference, you can then set about trying to identify what that difference is, and whether one case is an improvement on the other. -- Patrick Dixon www.at-tunes.co.uk Patrick Dixon's Profile: http://forums.slimdevices.com/member.php?userid=90 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

so . the amps pretty good ...klipsch have a good rep , though I've not heard that model.
