A sound of 2 sone is exactly twice as loud as a sound of 1 sone (at least for an average person...). That's why it's only a rule of thumb. The sensitivity of our ears changes quite dramatically across the frequency range, and the rate of change of perceived volume with power also changes with frequency and absolute sound pressure level. There is no specific number of decibels that equates to doubling volume, unless a specific frequency, absolute SPL, and subject are given. -cb - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]
MD: MZ-R50 Problems.
I've had my R50 since December, and since then have used it pretty heavily (about 3-4 hours a day). I don't keep my discs in cases, but haven't really had any problems with my unit until recently. When recording, it will insert bits of crackly noise into the recording. This is happening with new discs, and I even had a Sony ES disc fail after about a day of use a week or so ago. Should I try a lense cleaner disc? Does anyone have any other suggestions of what I could do for it? Also, the headphone jack, in the last two days has become very sensitive, and I almost have to hold the plug into position on the jack to get both audio channels. Anyone have any ideas about this? Thanks. Ollee. - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]

(The second thing I wonder is if these 24 bit converters are for real, since stand alone 24 bit ADC units cost thousands of dollars, and the new Sony MDs with 24 start at under US$300. But that's a whole nuther issue.) What are the specs of those 24 bit converters that cost thousands of dollars? An audio AD converter just needs to be 44.1 kHz. That's rather slow for a ADC. Note that if you use 8 times oversampling at the front-end, your AD converter runs on 44.1*8 Khz ie, 352kHz. I know a 200 Mhz 24 bit ADC costs loads of money but a ADC that doesn't even run on 1Mhz? They are normally very very cheap. Cheers, Ralph - Who's glad the ugly German is back! Ralph- Professional studio 24 bit A/Ds (and DACs) tend to have specs of 115-120 dB Dynamic Range and S/N of 108dB. The reason they are so damn expensive is because when you have that kind of dynamic range, you have to be very careful about various physical limits of electric signals before you convert them, i.e. the analog section, power supply etc. needs to be of the lowest noise possible, which means premium parts. At 24 bits (even at 20) you actually begin to run into the inherent thermal noise within resistors which cannot be eliminated, and this is why the S/N ratio doesn't match the Dynamic Range for higher bit rate converters (we can hear information sitting well below the thermal noise level). But aside from that, you seem to be confusing sampling rate with bit depth. Faster processors can certainly up the sampling rate--just speed up the clock; increasing the bit depth is all about good old analog electronics design expertise and much more difficult/expensive. -Alex _ Do You Yahoo!?

Does anyone have any other suggestions of what I could do for it? In my opinion no, certainly not if your unit is still under guarantee though I don't know whether you get just a basic 90 days or such like, or (and this is probably the best think about Britain) a one year shop guarantee on all new items regardless of the manufacturers warranty. Lens cleaner discs should only be tried as a last resort as they can all too easily act as lens scratcher discs and make a bad situation into a very expensive trip to the repair shop. Until you get lots of replies via md-l which suggest otherwise, *DO NOT USE A CLEANER DISC IN YOUR MD OR CD* Also, the headphone jack, in the last two days has become very sensitive, and I almost have to hold the plug into position on the jack to get both audio channels. Anyone have any ideas about this? You didn't say whether you were recording digitally or analog. If all the sockets have recently started shown problems I can't help but ask could "foreign particles"have found their way in. You weren't using it on the beach down in Os were you Ollee and a few grains of sand found there way in? A single grain could easily prevent a channel connecting (those contacts in the sockets are tiny spring loaded bits of metal after all). If the unit does have foreign bodies inside, they might be shaken out-- take care though as over vigorous shaking may break the mechanism. I guess the other alternative would be to dissolve the foreign bodies inside into a liquid solvent. I only studied Chemistry to A-Level but I guess either concentrated Hydrochloric / Sulphuric / Nitric Acid would react with any sand inside the unit removing the block. Perhaps some Chemistry student can help there. And if they aren't enough I think Hydroflouric acid will attack just about anything, hey isn't Flourine the only element which can bond and form a compound with Gold? ***STOP!!!***--- of course the above was a joke, do not do it, oh yes it might work, but it will remove your unit before the sand :-P Do NOT dip your MD into acid unless you wish to see your MD unit fizz as it dissolves.

Re: MD: decibel scale (was analog follow-up question)
=== = NB: Over 50% of this message is QUOTED, please = = be more selective when quoting text = === It has to come out the same either way. Sort of like when you use the DB formula and use power as a reference or use voltage as a reference. Since power P = V^2/R and R is constant, if you reference the voltage you need to use 20 log and if you reference power it is 10 log. It comes out the same either way. 3 db is double the power and a perceptible change in the perceived volume. Her is some info on it I found on the web http://www.neurophys.wisc.edu/~ychen/textbase/s1-p6.html Ralf Kuchenhart wrote: Ian Horsey schrieb: All there is to know about dB : The sound intensity level B (beta) is given by (10dB) x log I / Io [...] Back to ordinary dB - an intensity increase of a factor of two leads to a 3dB increase in sound intensity level. This change is barely perceptible to the human ear, and most people usually equate an increase of 8 to 10dB in sound intensity level to a doubling of loudness. So there is a point in doing a degree in Electronic Engineering! Hooray! Well, that's what you learn with an degree in Electronic Engineering, if you had some lessons in acoustics you would learn something more (or different?) I don't know the exact Englisch words for "Schalleistungs(pegel)" and "Schalldruck(pegel)". I would say sound power and sound pressure. The formular for sound power level is 10(dB)* log (I/Io), but the formular for sound pressure is 20(dB)*log (p/p0). If you regard the (electrical) power you need in your amps and to drive the speakers, your formular is absolutely right, Ian, but if you regard the electric level you record from the microphone, you have to use the formular for the sound pressure. Therefore, the step of 1 bit in the PCM code is always 6(.02) dB, not 3(.01) dB.

DO NOT use one of those head cleaners, as they can actually damage your unit. Most electronic shoppes should be able to clean your unit properly, or better yet, if you can take it in to an "authorized" Sony repair shop, they can clean it for you and make sure everything is adjusted properly. Also, the headphone jack, in the last two days has become very sensitive, and I almost have to hold the plug into position on the jack to get both audio channels. Anyone have any ideas about this? It sounds like your unit is suffering from abuse. The R50 really is a little tank, but you have to still be *somewhat* gentle with any piece of electronic equipment. Sometimes you can damage the headphone jack by jostling the cord or plug end while it's in the unit. I would check to makes sure that the problem isn't with the *headphones* first. I've had headphones break at the little stress relief point before. All in all, I'd say BE CAREFUL with your minidisc unit, or you'll break it.

MD: SoundVision Mag
I read Ken Pohlmans remarks too. He is so biased it is ridiculous. At one point he seemed to warm up to MD a little, but I think he is regressing. The thing that really pisses me off is how the same magazine is happy to pretend that the compression in MP3 is no big deal. In both cases, MD and MP3 they will state "less than CD quality" but with MD it is always a big negative and with MP3 it is no big deal. Go figure. I guess it is politically incorrect to be negative about MP3 since it is getting so much hype. Meanwhile, these editors gloss over the convenience and elegance of MD for recording, re-recording, editing, titling etc. No teeth gritting permanent recording. Never a mention of the benefit of portable recording. In the comparison to Dolby S cassette (and no, it wasn't a $2000 deck, it was a $650 deck) no value was assigned to the elimnation of the irritating linear format of tape, instant track access, editing etc etc. In fact, Ken's "audiograms" illustrating ATRAC elimination of frequencies above 18K I believe biased him beyond repair. Once he could see this, he thinks he can hear it. Go ahead, get a test CD and try to hear 19K hz. Without cranking up the volume. No mention that a Dolby S recording is of limited utility since the only Dolby S player you are likely to encounter to play it in is the one you used to make it. Does your car casette deck have Dolby S? Not likely. Oh well, I cancelled my subscription already. Rant mode off.

RE: MD: Control using hexadecimal serial data
Pehaps you will forgive me if I suggest this is a bit of a show-off remark. For those in the know, programming is indeed a trivial task for the most part, in fact one might say that the dreadful trivialities involved make it so difficult to do well. Sorry if this sounded "show-offy," I was really just trying to be helpful. When I said it was trivial, I meant it was trivial as far as programming goes. Indeed, much programming is most definitely NON trivial, and in fact quite difficult. This project, however, with the proper tools, is quite simple. In fact, I wrote the first version in about 45 minutes. Does this make me a brilliant programmer? Hardly! It's just relatively simple for someone who programs for a living. Hey, I can't work on my car, but that doesn't make me stupid, I just don't know the tools. On the other hand, suggesting that it is dead easy implies that those that cannot grasp the arcane principles required are a bit dim. I think programing at present is highly counter-intuitive. One day we will learn how to make computers work properly, but we've only just started. Again, I'm sorry if you took it this way; nothing could be further from my intention. However I disagree with your contention that programming today is highly counter-intuitive. How much time have you spent playing with Visual Basic or Delphi? If you try to jump right into Visual C++, your headed for trouble, but I have found that lots of people can master Visual Basic, and write useful little programs AND have fun in the process. If this is not your cup of tea, of course, you won't find it fun, but that doesn't mean that someone else wouldn't. FWIW, I have created a little program which should enable simple control of the MD player. It is just a test bed at the moment (a bunch of buttons and one setup screen for the serial port). I have looked at the serial port output of my computer with an oscilloscope, and it is definitely sending the commands, but I have no way to see if the thing actually works. I have sent a copy to the original poster and am waiting to hear back. Whan we have it working, I will be happy to send it to anyone who is interested.

Re: MD: SoundVision Mag
Actually, I have a mid-range Sony dolby S three-head cassette deck (paid about $300 maybe 6 years ago), and I will say straight up I believe the sound is as good or better than minidisc Atrac 4.0, if I do EVERYTHING right when making the tape, and I mean EVERYTHING, which is STRESSFUL as hell, and NO FUN, and a consummate WASTE OF TIME, and then there's no titling, no random access, no convenient editing functions, and either a minidisc or Dolby S tape is good enough to sound monstrously good on a damn nice stereo. The tape will diminish in sound quality over the years, my tape deck heads will wear out, you have to clean the damn heads all the time, it will NEVER ever be up to minidisc quality on a different cassette deck than the one I recorded the tape on. And I could GO ON AND ON A HUGE price to pay for a fraction of an ounce of sound quality. I think you can get a cassette deck for $300 that sounds just a tiny little smidge better than ATRAC 4.0 on certain types of music if you work like hell at it, but make no mistake, IT'S LIVING HELL. And perhaps ATRAC R has erased the nearly microscopic gap? Do you think I've recorded a cassette tape since I bought my JE-510? Don't bet on it, baby!!! With minidisc I just plain enjoy the music more. That's what matters most to me. If someone is that freaked out about sound quality, they should buy the best headphones and loudspeakers they can afford first, or maybe it would be cheaper to just see a psychiatrist I think SoundVision is about the most honest magazine of its type. Unfortunately, Ken Pohlman has had a bug up his butt about minidisc for a long time. He seems like a very diligent, honest and straightforward guy, but I think he's made a bad, and somewhat arrogant, call on this one. EEK!!! I've written too much!!!

False alarm, it just wasn't turned on in the mixer. I have both the digital and the analog connections made and the mixer will enable or disable either or both. Now the thing I can't figure out is why the mixer doesn't show balance controls. When I record form the CD inputs, either digitally or analog, the result is a stereo wav file. However, I should be able to adjust the balance controls and pan the image from the right to the left and vise versa. Soon I will be able to copy some MDs to my computer to play with them. J.
