My understanding is it's another form of jitter and is a problem even for single systems. Like I explained above in order to get rid of local jitter which can be a problem for single system, drift then becomes a problem. Drift in my opinion is a bigger problem because local jitter can be easily removed if your average clock speed matches. Everone that says I have a dejittering DAC should be concerned with serious drift. I don't know how much drift is serious though. Having a Master common clock gets rid of Drift, you still can have local jitter even with a common clock. But with drift removed the jitter can be fixed up easily. -- mswlogo mswlogo's Profile: http://forums.slimdevices.com/member.php?userid=9090 View this thread: http://forums.slimdevices.com/showthread.php?t=35866 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Any thoughts? I think I have bought my > last cd. In thinking about this more since my post, I do not think that 24 bits should make any difference other than dynamic range. I guess what is key here is the resulting voltage differential between neighboring bit values. ie) I think the voltage gain by going to say digital value 6 to 60001 is identical between a 24 bit word and a 16 bit word(both can represent this same value and correspond to the same change in voltage in the analog domain). So no additional amplitude resultion exists between 16 and 24 bits to make things sound "smoother". All the extra 8 bits gets you is more dynamic range extension on either side. This can be lost in the noise floor of most equipment; it can be of value in recording things at a higher level without fear of digital clipping, and at the same time having sufficient bits to capture the softest of passages. I think possibly what we are all hearing is the benefit of a good recording plus the additional musical information afforded by the 4Khz sample rate increase.

Re: [SlimDevices: Audiophiles] How good is the DAC in the Squeezebox 3?
My experience - the DAC in the SB3 is not bad. I think it's probably fair to compare it to a $500 or so CD player. When I first got the SB3, I erroneously bought a toslink cable which had a 'mini-toslink' connector on one end. As such, I was forced to go a couple of days using the analog output of the SB3 into my preamp/processor (Linn Unidisk SC). The sound quality was actually not too bad - it was free of digital 'edge' and had a coherent presentation across all frequencies (not goosed up in the treble or bass). Certainly, if you have a CD player which is more than 5-6 years old, I'd bet the SB3 sounds better. When I got the 'right' toslink cable, and let the Unidisk do the DAC, there was an improvement in sound quality. The music became more dynamic with a percieved extension in both frequency extremes. At the same time, there was more detail and the soundstage gained a sense of depth. So, in summary, the analog output of the SB3 is certainly competent, but if you have the opportunity to use a good outboard DAC (which will inevitably cost quite a bit more than the SB3) then you will get a worthwhile improvement in sound quality... or, I suspect you could use a Transporter instead. -- jbc jbc's Profile: http://forums.slimdevices.com/member.php?userid=11473 View this thread: http://forums.slimdevices.com/showthread.php?t=35642 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I say that because the differences between clock speeds are precisely the reason jitter is a hard problem to solve - if all clocks were the same there'd be no issue, as you could simply use a local clock rather than regenerating it from S/PDIF. Playing two players at once with different clock speeds is in a way the worst case scenario - the "distortion" will grow with time, and can become arbitrarily large on very long tracks.

It's a good observation though. No matter what Video/Audio will be in sync regardless of the FIFO setting (it has no control over the source clock or video rate) it's just what artifacts you want to trade off. It may have a fixed offset between Video and Audio which is what it allows to adjust independent of the FIFO.

Re: [SlimDevices: Audiophiles] Jitter vs. "Drift"
Some dejitter circuits would "fix" (mask) the slight pitch error as well. They have memories and buffer up the music and clock it out at hopefully a more accurate clock (the DAC clock). The problem with this is, that if the buffer overflows it has to toss data. Or if it underflows it has to wait. This can be a slight crack or pop. If the buffer isn't too big it won't get too far ahead or behind to notice. So it's trade off. On my Meridian system I can turn this FIFO on or off. The option is called "Poor Digital Sources" (i.e. ones with bad drift). If it's off it just locks on to the clock of the SPDIF. If on it uses the internal clock and the FIFO. It actually has 3 levels of FIFO's I think to help smooth buffer underrun and overrun issues. I don't know all the details. With the SqueezeBox 3 I can leave the FIFO on (i.e. SqueezeBox 3 is considered a "good" digital source). Poor Jitter will also give the FIFO fits. -- mswlogo mswlogo's Profile: http://forums.slimdevices.com/member.php?userid=9090 View this thread: http://forums.slimdevices.com/showthread.php?t=35866 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

JJZolx;206912 Wrote: > What are the sonic implications with regard to the simple, basic timing > ability of the Squeezebox when over the course of a long song the two > players can drift a full second or more apart? The "drift" is most likely due to slightly different frequencies in the clocks of the two units, probably arising from the tolerance in the reference crystal frequency. You would find the same sort of "drift" among any number of CD players you'd care to test. The only cure would be to use a single clock and distribute it to all units, but who would bother? The sonic implications are that if you are in ear-shot of both players, you're going to hear an echo. Otherwise, the pitch will be off on all the notes. Everything will be sharp or flat. But by how much? If there is a 1 second error at the end of a 10 minute song (600 seconds) the error is 0.17%. A above middle C is 440 Hz. A 0.17% error in that note is 0.73 Hz. I doubt even the most golden of ears can hear that (though I am sure a few will claim to). That's why the sonic implications are a non-issue.

OK, I was confused. I saw that the SB3 supported flac up to 48K and thought that that was a flac limit. Now I see that the SB3 will accept 24/96K but will down sample to 48K. So I could save everything as 24/96K and the only downside is the increased storage requirements. -- sataylor56 sataylor56's Profile: http://forums.slimdevices.com/member.php?userid=11883 View this thread: http://forums.slimdevices.com/showthread.php?t=19976 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

This one gets very close though: http://store.acousticsounds.com/browse_detail.cfm?Title_ID=11728&sct= Can't agree about using 44.1k for vinyl - makes it sound like a CD! Recording at 24/96 gets very close to capturing the original sound of an LP.

[SlimDevices: Audiophiles] Jitter vs. "Drift"
I find it mind-boggling that there are endless discussions regarding jitter, jitter measurements, jitter control, and all the rest when at the same time there are ongoing discussions about the difficulty of keeping two SB/Transporter players in sync during playback. With no mention from the jitter cognoscenti regarding the latter. http://forums.slimdevices.com/showthread.php?t=34535 What are the sonic implications with regard to the simple, basic timing ability of the Squeezebox when over the course of a long song the two players can drift a full second or more apart? -- JJZolx Jim JJZolx's Profile: http://forums.slimdevices.com/member.php?userid=10 View this thread: http://forums.slimdevices.com/showthread.php?t=35866 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Idiots guide to FLAC vs WAV vs MP3
Yes, my goal is "CD quality" although I have LPs that have consistently sounded better than many CDs. I have an old CD player though and my CDs are sounding a lot better after ripping them and playing them through the SB3. Anyway, the Edirol doesn't offer an 88.2K sample rate so I have to use either 44.1, 48, or 96. I compared recording at 16/44.1K and 24/96K and there was a distinct improvement in sound even when the final file was saved as 16/44.1. I have not tried 16/96K or any of the other combinations since it is all time consuming plus I have always tried to never play an LP more than once within a 24 hour period. I am just starting out on this so I was hoping I could bypass some of the trial and error by learning from others who have been down this path already. As far as I know, flac is limited to 48K but does allow 24 bits. To save the full 24/96K, I would have to save as wav which would then take even more space. I have around 700 LPs and 300 CDs so this is going to be a long project and will require a lot of disk space even as flac files. I do want to get this all sorted out before I get too far into it for exactly the reason Heuer stated, I don't want to have to re-rip at a later date. -- sataylor56 sataylor56's Profile: http://forums.slimdevices.com/member.php?userid=11883 View this thread: http://forums.slimdevices.com/showthread.php?t=19976 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

It is indeed one of the better auto declickers around, and has the advantage of being written in Java and therefore is available on other platforms as well as Windows. But there are other restoration tools which work well. The declicker in Adobe Audition is good, as is the Sony (formerly Sonic Foundry) Noise Reduction 2.0 plug-in. Another auto-declicker that is not well-known but which I feel gives good results is Wave Corrector. But the bottom line is that automatic declicking only does part of the job (and in some cases leads to audible artifacts). There are many types of vinyl glitch which can only be successfully fixed by careful hand editing using an audio editor. Unfortunately this is a tedious process and unless you're the sort who enjoys it as a pastime, it may well not be worth the effort.

I don't understand why you're saving at 16 bit if you feel that you need to record at 24 bit to capture the LP. As it happens, I strongly believe that 16 bit is more than adequate for LP recording. The noise floor of even the best LP is typically no better than -60dB below 200Hz, and although it improves at higher frequencies, it's never better than about -75dB. And I've never seen a phono preamp with a noise floor as low as -96dB. As for sample rate: while most LPs have some sort of signal above 20kHz, it's typically all noise and distortion. Indeed, most LP cutter heads have low pass filters to prevent exciting resonances. So most LPs have no programme material on them above about 18kHz. I've personally never found the need for higher sample rates that 44.1kHz. -- cliveb Transporter -> ATC SCM100A cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=19976 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Idiots guide to FLAC vs WAV vs MP3
Never personally compared the SQ difference between 44.1k and 48k but perceived wisdom does suggest that downsampling from 96 to 48 is cleaner than going to 44.1 becuase the former is half the frequency. If you are doing 16 bit anyway you might as well go for the CD friendly 16/44.1k rather than muck about with a hybrid 16/48. The only thing I would say is that in two years time technology will have moved very quickly (SB4, 1Tb HDD etc) you will be wondering why you did not save everything as 24/48 or 24/96. Takes a long time to re-rip all those albums and it will gnaw away at you thinking you are missing something! -- Heuer Heuer's Profile: http://forums.slimdevices.com/member.php?userid=2543 View this thread: http://forums.slimdevices.com/showthread.php?t=19976 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Idiots guide to FLAC vs WAV vs MP3
I am using an Edirol UA-1EX to record at 24/96 with Audacity. I export the file as wav and then run ClickRepair on it. I then reload into Audacity and export as flac. I am playing these files via a couple of SqeezeBoxes on two different systems in my house. The whole process takes time but it sure works great! My question is, would I be better exporting at 48K vrs. 44.1K? I am saving my files as 16 bits and my thinking is that since 48K is exactly half the 96K original, it may produce better results than converting to the CD standard of 44.1K. I've already determined that the original recoding needs to be done at 24/96 instead of 16/44.1 to preserve as much of the sound of the LPs as possible. I also quickly dismissed saving the files as MP3s, even at 320Kb/s the sound quality is clearly inferior to the 16 bit flac files. I just haven't done any testing to compare 16 bit flac files between 44.1 and 48.

Personally I use an e-mu 0202 USB ADC connected to the tape out of my pre-amp. http://www.emu.com/products/product.asp?category=610&subcategory=611&product=15186 If you want a quick an easy way of capturing the WAV and auto splitting into tracks the Spin It Again software is superb. http://www.acoustica.com/spinitagain/ You can use Audacity, Wavelab or Audition but expect a steep learning curve and a lot of time spent! If you want to remove clicks then Click Repair is king. http://wwwmaths.anu.edu.au/~briand/sound/ Pointless keeping the files in WAV format so I use Flacfrontend to encode to FLAC and MP3Tag to edit the tags. My preference is to record vinyl at 24/96 as I use a Transporter but if you are using an SB3 you may want to consider 24/48 or CD friendly 16/44.1 . But given it takes so long to do needle drops I figure you should go with the highest practical sample rate to keep the recordings future proof. You can always use Audacity to downsample if required but obviously you can't go the other way. -- Heuer Heuer's Profile: http://forums.slimdevices.com/member.php?userid=2543 View this thread: http://forums.slimdevices.com/showthread.php?t=19976 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
