MD: Sorry, seriously OT: for dutch subscribers, speciaal voor nederlanders

[meeder]

Hier een leuke tip waardoor je als het meezit een goede slag kan slaan.
Let op het gaat als volgt:

Een sterk groeiend Internet handelsbedrijf "Freebanco" geeft gratis
aandelen weg als promotie stunt om naar de beurs te gaan.
Ze zijn net begonnen en willen naambekendheid krijgen. Stap je er nu
in, dan ben je er (nog) vroeg bij.

Het laatste bedrijf dat dit deed was Yahoo! Dit aandeel staat nu
genoteerd aan de NASDAQ en is inmiddels 3500% gestegen sinds de
introductie. Freebanco kan net zo groot worden of het wordt niks, maar
het kost je ook niks dus proberen maar.
Schrijf je in via Internet op onderstaande wijze en daarna kun je (a la
deze mail) andere mensen benaderen die op jouw e-mail adres hun gratis
aandelen bestellen.

Voor iedereen die een aandeel bestelt onder jouw e-mail adres krijg je
namelijk 3 aandelen erbij! Het is gratis en zonder risico, dus het
proberen waard! Als het aandeel stijgt heb je een leuke bonus, als het
daalt is het jammer. Maar...er is niets aan de hand want je hebt er
niets voor betaald. Je kunt regelmatig checken of je eigen
aandelenvoorraad zich heeft uitgebreid. Je krijgt nl een bevestigend
mailtje (virusvrij). Er zijn geen valkuilen of rare dingen.

Inschrijven gaat als volgt:
1. Ga naar
http://freebanco.addr.com/index.html 

2. Aan de onderkant/zijkant van de pagina staat een afbeelding "FREE STOCK",

click daar op
3. Click weer onderaan bij registration en vul je gegevens in
4. VUL WEL MIJN E-MAIL ADRES BIJ "REFERRED BY" IN.
5. MIJN E-MAIL ADRES IS: [EMAIL PROTECTED]
6. Na het invullen van de gegevens klik je op "Submit" en dan krijg je
een bevestiging van de registratie.

Vervolgens krijg je 5 aandelen. Voor iedere nieuwe persoon die zich via
jou inschrijft krijg je 3 aandelen. Dat kan dus behoorlijk oplopen.
Nogmaals het kost je niks en wie weet wat het aandeel doet.

Succes ermee!

Re: MD: sb live value and CD rom

[J. Coon]

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.

Jough:

That is your personal opinion, but it is not necessarily true from an 
ergonomic standpoing. As someone who has had some pretty bad RSI 
injuries, and hence had quite a bit of RSI training, I can say quite 
confidently that *used* *properly* the button approach is much less 
likely to give you an RSI than the Sony jog dials.

Long version: The Sharp buttons require much less force to push than the 
Sony dial (mainly because the Sony dial both rotates and depresses, so 
they have to add "stiffness" to the depression so you don't accidentally 
depress when you're trying to rotate). If you title on the Sharps by 
holding the character advance/reverse buttons down rather than repeatedly 
pressing them, you are using much less "downward" force on the Sharps. In 
addition, the dial on the Sony requires that your thumb (or finger if you 
go that way) must make many, many short, repetitive movements as you roll 
your thumb over the wheel. On the Sony, titling a single song with a 30 
character title requires 30-90 repetitive motions just to get to the 
correct letters (assuming one to three "rotations" for each letter), plus 
30 depressions of the stiff jog dial. On the Sharp, it requires 30 
press-and-holds of the character selection buttons (which require much 
less force) and 30 light depressions (to "set" each letter). From an 
ergonomic standpoint, the Sharp isn't great, but the Sony jog dial on the 
MZR50 is an absolute nightmare.

That's the ergonomic review. From a "convenience" point of view, titling 
on the Sharp is slow. You can definitely title much quicker on the 
Sony. I've gotten where I can pretty much hit each letter on the nose 
with one "roll" of my thumb. But when I'm speed-titling, my thumb/hand 
starts to hurt pretty quick -- it's not a good thing to do for too long.

I usually end up not titling my MDs. My girlfriend's Sharp is too slow, 
and the Sony hurts after a while unless I slow down and add enough 
variety to my movements to avoid the repetition -- making it, too, slow. 
I'm about ready to go buy a component deck just to title ;-)

Re: MD: Sound&Vision Mag

[Steve]

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 Sound&Vision 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!!!

It's a matter of two things.  One the ear hears on a logarithmic scale,
and second what the perceived loudness appears to be is dependant on the
distance from the sound source, which is not particularly pertinent in
this query.  Hence a 100 watt Marshall amp does not sound twice as loud
as a 50 watt amp, assuming same type of amp at the same distance.  What
sounds twice as loud at 3 metres would not sound twice as loud at 6
metres (approximations used.)  It was always taken that you required a
3dB increase for the human ear to notice any increase in loudness.

Just my musing, but thought maybe of interest.

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.

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.

MD: Sound&Vision Mag

[Lfmcarthy]

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.

It sounds like your unit is dirty.  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.

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. 
You have to learn how to take care of your toys.  ;)

Let's see... a short spin of a little wheel... or a repetitive pushing of a 
button...

The 702 is a chore to title with.  A jog dial is a superiour method of 
selecting most items than a button is.  Buttons should only have to be used 
if the list is very short.  I don't think a list of ~80 characters 
constitutes "short".  The jog dial is quicker and less stressful to the 
hand than many button pushes are.

Sure, if people title a lot they may get RSI, but they're few and far 
between.  If you do *anything* enough (like say, push buttons perhaps) you 
*could* get an RSI.

As I've said before, if your R30's jog dial gives you pain, it's probably 
broken and not able to spin properly.

You are using a TOSlink digital optical cable, so your recordings are
definitely digital.  The unit does not pause because it is always receiving
digital information from the soundcard, as long as it is connected and the
soundcard's digital out is active.  When Winamp has finished playing, you'll
find that the soundcard is transmitting valid S/PDIF data, but with zeroes
(ie. silence) for the audio bits.  Your recorder is faithfully recording the
silence being presented to it.

Nope, TOSlink optical is digital only.  It sounds to me like your setup is

MD: mono capacity of buffer (was question on MZ-E40)

[David W. Tamkin]

Zach asked,

I haven't tried it with a portable, but with my decks I can tell you these:

1. When tracks are played out of their physical layout order (because of
program mode, shuffle mode, or a resequenced TOC), you can hear the head
seek twice as long before the end of a mono track than it does before the
end of a stereo track.

2. When I am using relay play on my W1, if the last track played on deck A
is in mono, deck B cues up when there are twenty-four seconds left, but if
the last track played on deck A is in stereo, deck B cues up when there are
twelve seconds left to play on deck A.

So I'd conclude that yes, the buffer is used to capacity and its contents
play for twice as long if they're mono as they do if they're stereo.

No don't use a lens cleaner except as a last resort.  

Send it in for repair,  it should still be under warranty.

That one you might try cleaning the plug and making sure it is polished
nice and shiny,  (Could be that peanut butter and jelly sandwich) but if
you are taking it back for repair, let them repair that too.

Re: MD: decibel scale

[PrinceGaz]

Since this topic is continuing and I have nothing better to do before the
Vision channel starts on cable at 4am, I'll post this from my Wharfedale
speaker manual: [anything in square brackets like this is my own "witty"
comments].

Very Faint:
0dB- threshold of hearing
6dB- human breathing [assuming you don't wheeze]
10dB- rustle of leaves in breeze [not breaking branches in hurricane]
20dB- average whisper

Faint:
30dB- Average domestic background level- no music playing
40dB- Very soft radio music playing in house

Moderate:
50dB- Average office [presumably one where eveyone isn't chatting]
60dB- River or streamside, running water [no not Niagara Falls]

Loud:
70dB- Typewriter or computer print room [obviously not inkjet / laser]
80dB- School playground or cafateria at break time

Very Loud:
90dB- Noisy factory or noisy urban street with lorries [should use rail]
100dB- Car horn at 10 feet way [3 meters]

Deafening:
110dB- Accelerating motorcycle at 10 feet away, avaerage discotheque
120dB- Threshold of feeling.  Rock concert.
130dB- Threshold of pain
140dB- Near jet engine during power take-off [distance not specified]

People at home listen to classical music at an average level of 80-85dB,
rock music at 90-95dB, and most parties start at around 80dB and run up
to 110dB beyond which they attract police attention.

They go on to mention most speakers produce a sound level of 88dB from
1W at 1 meter, and doubling the distance to 2m requires twice the power
so 1W would give 85dB at that distance.  It then mentions the "smallest
increase in loudness" takes 3dB or twice the power, and to increase the
loudness two-fold takes 10 times the power, and goes on to warn how and
why an over-driven low power amp will destroy your speakers much quicker
than an amp with plenty of watts driving the speakers to, or even beyond
their rating provided the signal isn't clipped.

I do care about my ears and worry that I sustained a level that must have
been 105dB average at my listening distance for over half an hour when the
workers next door were hammering and drilling on the wall.  I know it's not
clever, I just wanted to drown out the noise.  At least there was no perceptible
distortion so the workers got reasonable quality sound (given a wall 'tween
us :-)

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.

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*

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.

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.

When you say electric level Ralf, you need to be a little more specific.
The voltage level follows the 20log... formula, but if you measure the power
being delivered by the microphone to the preamp, it still follows the
10log... formula, as any electrical power ratio always will.

When talking PCM code, you are always referring to digital representations
of voltage, not power.  That is why every bit adds 6.02dB of dynamic range.
By doubling the available voltage range (adding 1 bit of resolution) we are
quadrupling the available power range, and this solves in the 10log...
formula.

MD: MZ-R50 Problems.

[ollee]

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.

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.

Re: MD: decibels

[meeder]

When you double the amplitude you will get an 6dB amplification according to
the Soundforge 4.5 manual.
it is an logarithmic scale. When you have a amplitude which is at half of
the scale you will get 20log(0.5) = -6dB. If you double the amplitude you
will get 0dB
