How can I tell music has been an MP3? Quantitative Measurement of Fidelity

: No, I've never seen that numbering - I've got one or two sets numbered 1/4 & 2/3 and plenty numbered 1/2 & 3/4. 1/4 & 2/3 is designed for automatic record changers. Put the stack on the changer. 1 drops first, then 2. Flip the two-record stack and put it back on the changer. 3 will drop, then 4. |

I use Sheldon Stokes' DAC, which has a 6DJ8 output stage. It sounds good. It probably sounds good more because it's well-designed with careful layout than because the output stage is a tube, but it's pretty clean. He does the I/V stage on the output of the ladder (a PCM-63) just with a shunt resistor to ground and then pulliing off into the high-Z input of the tube grid. This gives comparatively poor S/N, much worse than an active I/V stage, but I think it sounds better than a conventional active I/V stage. You could do the same thing with a FET-input op-amp and it would probably sound just as good, though. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I have been disappointed with the audio quality of some CDs I have bought recently. Is there a free program I can use to get an accepted measurement of fidelity? (like a signal to noise ratio) No, you can only listen. I have my suspicious that some may have been stored an MP3s and then "unripped" in the factory. So how can I tell for certain if my CD has been an MP3, or other lossy format? I'd hope mp3 storage would leave different markers than the original tape, for example. This will never be the case for a major label release. However, as an increasing number of records are issued by amateurs who don't necessarily have a clue what they are doing, you may find this on some small releases. More likely you are heaving the massive overcompression and limiting which is currently fashionable. Everybody wants their recordings to be louder, not necessarily to sound good. To get a good measure I'd expect some Fourier transforms and signal analysis to be done, so this should be relevant to sci.physics. If you play back a recording made with a perceptual encoder like MP3 uses, and you look at the spectrum with an FFT (using a program like SpectraFOO or some other free FFT application), it will be very obvious that something goofy has been going on. You'll see these big square blocks of spectrum popping in and out. If, on the other hand, you play back a heavily limited recording on an FFT application, you won't see much other than that the plot is a lot denser than it otherwise would be. --scott -- "C'est un Nagra.

I'd suggest that this isn't a recent phenomenon. I've got plenty of pop vinyl from the 1970s and 1980s that has roughly no dynamics. Making crap sound louder on the radio at the complete expense of quality is decades old. That vinyl was pumped to hell and back with massive compression, BUT it wasn't aggressively limited as well, because aggressive limiting didn't really improve loudness on vinyl much. Today with the CD there is a hard limit for level, and so you hear a lot of heavy peak limiting today. That's more destructive to the overall sound. The combination of the two is an absolute killer. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

The disaster would be short-lived and not on the air; a disc that's cut center-out can't be cued up at the outside rim, as the groove is going in the wrong direction. (Vice versa, of course.) So the operator would realize the error during the cue-up process, which would typically be done as soon as the previous changeover had been accomplished.. Peace, Paul |

How can I tell music has been an MP3? Quantitative Measurement of Fidelity
Classical 78 sets came out in two numbering schemes:
Manual - 1/2, 3/4, 5/6, 7/8 Automatic - 1/8, 2/7, 3/6, 4/5 For an automatic album, you used a changer and stacked the discs in order, with 1 on the bottom and 4 on the top. When 4 was done, you flipped the stack and played through to the end. If someone was playing the discs on air, or in a "gramophone concert", they'd need to either have two copies of the 4/5 disc or do some sort of a break (commercial, commentary, etc.). But this very seldom happened, at least in the USA; classical music on air, when it happened, was mostly live up until the LP era. And we didn't have gramophone concerts much here. As to who had the money for two turntables -- radio stations, that's who. Before satellite networks, when microwave links and equalized phone lines were the norm, some programs went out on transcription discs, 33-1/3 coarse-groove, 15 minutes per segment. Peace, Paul |

I thought that "Music is the space between the notes." was John Cage, but more research seems to attribute it to Claude Debussy. I would imagine that it has been paraphrased a few times by other people. |

I grew up in what was then a small village (in the UK) and I'm pretty certain 'gramophone concerts' were held in the village hall from time to time, but that would have been before I was old enough to go. The nearest I got was 'music lessons' in the primary school I attended when the headmaster played records to us and although I can't remember the record player (gramophone?) too clearly, I'm certain it wasn't an autochanger. I do vividly remember the music though - stuff like Greensleeves, Grieg (Peer Gynt) and various Ketelbey tunes. Anyway, this got me interested to Google and I found this site: http://www.cph.rcm.ac.uk/MusicRoom/070115Summary.htm There are some very interesting references and observations, including the notion that the so-called 'WAF' is nearly 100 years old and I particularly like this bit: "To catch a friend listening to the gramophone alone would be equivalent to finding them 'sniffing cocaine'." :-) |

It's interesting that the much more common 1/2, 3/4 numbering system doesn't allow a smooth changeover on a single deck, offers no advantage over the above 'single deck' routine on two decks and doesn't even work on an autochanger...?? |

Of course they sound DIFFERENT. But have you actually *heard* one...?? Very many of each. Although "heard" may be the wrong term in the case of any good amplifier. Any coloration you hear in almost all cases is the speakers and the acoustic environment they are located in. If you do hear a major difference caused by an amplifier, then the amp is seriously flawed. And it's funny that when solid state amplifiers did get so close to the ideal "piece of wire with gain" many years ago, some people started paying big dollars for "better" cables :-) Which is not to say there aren't some seriously flawed and even unstable solid state designs around if you look hard enough. Just not as many as seriously flawed tube designs these days. "Better" is purely a *subjective opinion* in that case with large numbers in each camp. *Objectively* there is no contest though. The distinction is lost on non technical people unfortunately. Lost on me, that's for sure - what is the distinction? If you don't understand the difference between objective testing, and subjective opinion, I suggest you do some basic research.

It might be larger, and would have so many tubes that it many never actually have enough good tubes in place to work. There might also be some problems with data rates. Tubed computers never got real fast. |

With a sigma-delta system, the main switch and the integrator and analogue section are all that you'd have to use tubes for. You could argue the constant voltage source had to be tubed as well, but the digital side could be all solid state. Doing this you could probably do the whole thing in fewer than a dozen tubes, but the main switch would need to have very wide bandwidth and a nice square switching waveform. Frame grid tubes wouldn't cut it, gas tubes are way too slow. You might be borderline for a nuvistor. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Frame grid tubes wouldn't cut it, gas tubes are way too slow. You might be borderline for a nuvistor. But it takes the equivalent of thousands of transistors just for the motor drivers, head positioning, fine pickup position servos, etc. etc. Surely doing all that "housekeeping" stuff with nice warm-sounding tubes will improve the sound of the output. And, of course, you need a good incandescent light source, properly filtered and focused, to put some "life" into those ones and zeroes that are being read off the spinning disc. :-) There is more computing power in my optical mouse than in any of the tube-based computers. |

Once again you forgot to add the important "In YOUR opinion". Oh wait, you haven't looked up the definition of opinion yet. MrT. |

Some of it I did, and when I was under 12 years old, I didn't notice the difference. That doesn't mean that it's their moral perogative to contiue producing crap. Much of it I've picked up recently, for $0.50 per album at garage sales and used record shops. On a whim, I got Kim Carnes' "Mistaken Identity" tossed in when I bought a turntable a while back. Thing is about 0.03db between the loudest and quietest passages. Horrible to listen to. Compressed audio like 'Classic FM' on a car radio works very well, actually.... True, car audio is a different beast in many ways. Many of my favorite albums (on CD, that is) don't come with me in the car, because the volume I need to listen to 70% of them makes the remaining 30% painfully loud. But they sound brilliant at home.

The equation is a simple one - if crap is bought, then crap will be produced... The equation is even simpler than that: Companies will do as little as possible to make a profit. Quality costs money. As long as they can find a way of selling things without 'wasting' money on quality, they will. Or even simpler: Companies suck. The days of good 'threefers' and 'forfers' (charity shop 'bundled vinyl' offers) are gone. Worthwhile vinyl is a few quid a slice now and no longer peanuts off Fleabay, what with the postage, these days... Nah. I've picked up a handful of good cheap vinyl, but it's harder to find. Got "Twisting by the Pool" a few months ago for a buck, and it had hardly been played. Good sound all 'round. For half a buck or so, I can take a few risks to get a worthwhile album now and then. As often as not these days though, I find that I'll download a decent MP3 of a remastered album before deciding whether or not to buy it. I don't think I've bought an album without hearing it in a few years now, except for concert albums. (Although I'm really kicking myself for not buying an album I heard in a record store in central Holland a few weeks ago, because I can't find it available anywhere in North America, now that I'm back home).

(We don't see that in ukra too often, these days - not since Pinky ****ed off.... :-) I've picked up a handful of good cheap vinyl, but it's harder to find. Got "Twisting by the Pool" a few months ago for a buck, and it had hardly been played. Good sound all 'round. For half a buck or so, I can take a few risks to get a worthwhile album now and then. Sure, but I can't do 'good cheap vinyl' and "Twisting by the Pool" in the same sentence - I was thinking of this kinda thing: http://cgi.ebay.co.uk/ws/eBayISAPI.d...4311&rd=1&rd=1 Time was (before I shot my mouth off about the all valve/analogue 'Slavic' recordings and obviously sparked off a bit of a rush) you could have one of these arrive for about 3 quid. Now, it's double that and rising... As often as not these days though, I find that I'll download a decent MP3 of a remastered album before deciding whether or not to buy it. I don't think I've bought an album without hearing it in a few years now, except for concert albums. Hearing secondhand classical is nigh impossible on the UK - secondhand record shops rarely carry it and charity shops (that do carry it) understandably don't have the facilities. Mind you some of the cueing disasters I've witnessed in the secondhand shops (on very dubious decks) mean that you usually don't ask them to play a second one... (FWIW, I've never been disappointed with any eBay vinyl yet - the worst was a *brand new* Bladerunner bootleg that was pretty dire and the Seller sent me *two* more FOC to 'try and get a good one' and promised to kick his supplier's arse over the quality for the *next batch*...!! :-) (Although I'm really kicking myself for not buying an album I heard in a record store in central Holland a few weeks ago, because I can't find it available anywhere in North America, now that I'm back home). Contact the shop (must be findable) - even the Dutch have international post now... :-) |
