Ruh Roh, Monica – I think you’ve created an Audiophile.
If Dietzel can figure out how to get a record on the spindle without scratching it up, and cue the tone-arm without thumbs, you’re in trouble…
But I still say that a properly engineered and mastered CD through a high-quality CD player can be just as good a source as Vinyl, and without the dirt & dust pops. And without the record and stylus wearing out.
And there are double-blind studies that agree with me.
Who sez Dietzel don’t got thumbs?
(reference panel 3)
Agreed – he can play jacks, call and order pizza, open the door for Pizza Girl, and can put on costume elements – I don’t know if he loaded his own CD or not, but still…
It’s called Cartoon Biology (it’s like Cartoon Physics)
Could i ask where this avatar comes from?
It explains a lot…
pfft. horseleavings. They did actual double-blind tests. Same results every time— even the most fanatical audio Nazi couldn’t tell the difference between the high end, overpriced tube-based gold-plated-cable hi fi system and a typical CD player stereo. Any difference you hear (other than the pops, crackles and SCRATCHES you get from any record played more than once) is entirely in your head.
This is comparing Monica’s system to Dietzel’s crappy CD player. There is a difference.
I never heard that the Bose was crappy – just over-hyped.
Yeah. Now, if he were listening to my cheap-ass Magnavox boombox from the eighties… then we’d be talking…
I have tin ears, no question. Bose bookshelf speakers have always sounded great to me, and I like them a lot. But paying the price of a pair of bookshelf speakers for a @#$%^&* clock radio? I hurt myself laughing.
Mad Magazine tore them up for that, too. Saw it it a remaindered and discounted compilation volume.
I think the point is, ANY system that has to fit a good pair of speakers, a good CD transport and amplifier etc..in a box
10 cm High, by 40 by 20 (yes that is the size of the wave from the website..), would be hard pressed to get as good as having a good 4 foot by 2 foot speaker, driven by a good heavy power amp.. heck if you just took the audio out from the bose it would sound better 🙂
Bose doesn’t sound too bad…If one likes “woolly” sound. Definition is “Mweh”
Agreed on the over-priced bit. Bose costs about $50.-too much per letter.
Well, you know what BOSE stands for, right ?
Buy Other Stereo Equipment 😉
RHJunior, the first rule of playing LPs is to have a good wash and vacuum system to clean the record before playing it, and to use it every time.
This site offers several Nitty Gritty systems, as well as other brands, to fit most every budget. Check the “Record Cleaner” links under the header.
Ruh Roh, Monica – I think you’ve created another sound snob.
(fixed it for you….!)
I assume that is a Bose…and I would agree with Monica. They are pure unadulterated TRASH! My old sony discman hooked up to my computer speakers has more capability. Then again,, my discman was from back when they made them -good-. Damn near indestructable and high quality sound.
My ex wife never forgave me for teaching her what audio equipment should sound like.
yup, nothing so heartbreaking, when you have a great sound, and decide to upgrade your speakers for a £1000…. and then realise how much they covered up your awful player!!! :'(
Well, since Monica has invested about $15000.- already, that should not be a problem for her..
Bose is almost as big a swindle as Monster.
That is a Wave, isn’t it?
Sure looks like one. I really love the $100 plus AC power cords.
I’ve see the BOSE acronym as: Buy Other Stereo Equipment due to over priced outdated technology. That being said I have a pair of 201’s and 301’s that I picked up while I was stationed overseas. Of course that was…ahem…quite some time ago, but they still sound great.
One thing I do know is that if you want good low range response, size does matter: a 16″ woofer will sound better than an equal quality 10″ woofer.
…assuming equal quality of design and construction of the enclosures.
A 10″ driver in a well-designed bass reflex enclosure made with care and with quality materials will sound a lot better than a naked 16″ one…
Isn’t the only thing Dietzel needs to do is get a green marker and draw on the edge of the CD to help keep the laser from scattering or some other thing to improve the sound that audiophiles have told us over the years? 🙂
Dancing a Hula at full moon, holding the CD will do about as much, me thinks..
Guy I knew made a cd sound better by cutting it with tinsnips. Made the most satisfying shattery cruch. 😀
He did not prop himself up with the cd; he destroyed it. Typos suck.
Usually I let this slide but Deitzel has always known the difference. I am sure Monica has played her stereo system with him around before this. Since a dogs hearing range is even greater than a humans he has even a better idea of the full range of sounds than Monica. No set of tubes can improve any system that much. Also what is crap of the CD player is the speakers in it, not the system itself.
It’s not so much the quality of the system as that he was listening a CD. Frequencies above our normal range of hearing can influence the sound we do hear. In digital recordings, these frequencies can actually distort the audible sound, so some is filtered out. In analog recordings (like her record) this distortion doesn’t occur, so nothing is filtered out. BTW, if I got any of this wrong feel free to correct me.
CDs sample @40KHz which allows them to reproduce ~20KHz, but they can’t reproduce anything more than a sine wave at that frequency. So, all harmonics above 20KHz are deleted from a CD recording by the sample rate. If your hearing goes above that (like most dogs’) then what you hear from a CD is terribly distorted compared to analog.
And reproduction from a CD is dependant on 1. the bit rate of the sample, 2. the slew rate of the D/A converter (which is proportional to the bandwidth), 3. the bandwidth of the output amp. I used to be an electronics tech back at the beginning of the CD era, mostly consumer stuff after I got out of the Army working on telephone stuff.
It’s not that they can’t reproduce anything but a sine wave above that frequency. The system samples more than 24,000 times during each cycle of a 20kHz signal – more than enough to reproduce rather more than a sine wave with good accuracy.
The reason for the 20kHz cutoff is that you get nasty aliasing on freqs above half the sample rate.
(I did a longish post about this which also seems to have evaporated… In fact, it seems to me that several posts may have been lost.)
Yeah, not sure what happened, I can’t find any record of those posts. :/
Hmmm. I think i said something dumb.
I didn’t get much sleep this morning, and i was groggy when i typed it; and i’m only half awake now so i can’t parse it to be sure how stupid i sounded…
Average human hearing range 20Hz to 20Khz,
Average human Voice range 40Hz to 7Khz,
Being tone deaf PRICELESS
Well, crud. That includes all of mine…
(except this one)
I just was thinking about the nothing-but-a-sine-wave-at-20kHz thing, and i realised that i was sort-of right, despite being completely wrong:
Yes, it can only reproduce a sine wave at 20kHz.
And it can reproduce a sine wave at 19.999khz.
And it can reproduce a sine wave at 19.998khz.
And it can reproduce a sine wave at 19.997khz…
All sounds are composites of sine waves.
The possible problem with the “brick wall” filters used in mastering CDs that some advance is that signals above the auditory range may interact with audible ones create products that are in that range.
Personally, i think that if such signals existed in the initial recordings, they will exist on the CD.
For instance, there was the process developed by an Australian recording engineer that could create true stereo imaging from mono recordings and could recover sounds that were outside the capabilities of the equipment used to record the music by analysing the results of such interactions.
If there was a 500Hz component of the original sound but the mikes used had a lower cutoff of 1kHz or higher (as was the case in one particular Bob Marley recording he demonstrated with), there will be 1.5kHz and 2.5kHz components of the recorded signal due to the heterodyning of that signal with 2KHz components – and similar components for every other frequency that mikes could handle.
Similarly, you can use such heterodyning and other cues to recover information as to where each sound source was in relation to the mike (or mikes).
Just as with creating 3D images from flat originals, it’s a matter of knowing some basic facts about the original production and then throwing enough computing power at them.
oh WOW… you just sprayed your nerd musk all over me.
I’m in love <3
That’s very interesting. The question I have is, how does one distinguish between a heterodyned 1.5KHz signal and an actual 1.5KHz signal?
SoWhyMe: you need to do more research 🙂
the heterodyned signal is not ‘pure’ – If you have fantastic hearing tonality, you may notice some distortion, but it is usually far above human or even dogs hearing!!
this pic from google image search may explain..
Ok, but I was talking about how does one, using a spectrum analyzer or whatever, determine the difference so it can be processed appropriatly by said equipment/program so as to recognize the heterodyned signal from normal signal of the same frequency. Fairportfan indicated doing so can recover the frequencies below those which the microphone was actually capable.
You seem to be saying the heterodyned frequency is impure, so the equipment can use this information to determine which is which?
this is getting way beyond the size and ability of this comments section, AFAIK.. I certainly do not want to risk overloading paul’s server more, and losing more stuff!! 😮
I can answer your questions more fully,
*Please* continue here, its easy to register… 🙂 🙂
I had one that vanished too–about human hearing only going to 23 kHz, but dogs hear sounds up to 45 kHz. This means that they could be hearing and responding to sounds that we can’t hear at all, but it also means that our systems are designed with our limits in mind. Cats can hear sounds as high as 64 kHz, bats up to 110 kHz and porpoises up to 150 kHz! They would hear many of our music systems as very weak in harmonics and on the top end in general.
But there’s a natural mechanical high-pass filter in a record cutting lathe where it isn’t going to record anything much over 20KHz – the electronics chain might capture a signal, but the cutter head can’t move the tip fast enough to capture it on the master.
And the same thing with playback – Dietzel isn’t going to sense any difference there.
That said, there are still a lot of really badly mastered CD’s that were sold out there, where they just grabbed the master tape that was all EQ’d and compressed for cutting an LP, mailed it to the CD pressing plant and said Go.
And the results do sound okay, at least to a record company executive with a tin ear and a tight wallet for remastering costs… But put it up against any actual audio scrutiny, and it’s an Epic Fail.
But that’s my point! Our human systems are designed for us–other species would need a different design for their limits. For example, Dogs (and cats) would not get much out of color TV–B&W would do virtually as well–but cats could use a much wider range of light to dark. Many birds and reptiles (plus others) would need a much more sophisticated color system because they have 4-color sight; others would need a wider (or shifted) spectrum, often more into the Ultraviolet. Stomatopods have a dozen types of color cones–imagine what colors they can distinguish!
It’s “aliasing” creation of spurious signals – when frequencies equal to or greater than 1/2 the sampling frequency are included.
In essence, such a signal would be sampled twice per clock cycle, with opposite phase…
Now that would be interesting to have hearing as good as a dogs…
Mind you even the whole story of human hearing is not that well understood.. It could well be, that a dogs different ear physiology would accentuate various harmonics out of range of humans, and change the sound?? oh well, just a thought… :/
No, not really. It would only aggravate the percieved noisyness of our society.
It must be quite awful to hear every high-pitched sound our technological society makes.
And don’t even start about music. Our dog always started wailing loudly when we tried to play guitar music, or stuff with brass in it. Must have sounded horrible to him.. 😛
ah, good point.. many things we cannot hear, must give dogs a pain..
And I have not seen him listening to the bose before? It could have been a long time ago, and he has got used to Monica’s hifi… thus the shock at the hypersonic whining and rattling he had not really noticed before…
It would be even worse with a dog’s sense of smell. Theirs is 1,000 to 10,000,000 times more sensitive than a humans (depending on the breed). Of course we would also have to have a canine snout to make that happen. OTOH, we would be able to pick up many more clues about the state of our fellow humans. The wearing of heavy perfumes or some sort of masking scents would be popular to help keep our secrets to ourselves. This is supposedly why women started wearing scents early on in our evolution. To keep the male from being able to tell when ovulation occured. That way she could keep his interest all the time instead of mostly during some sort of rutting interval.
Poor Dietzel! That puppy needs a hug! Shame on you Monica!!! 😛
Oh…and I like the little detail on panel three…where you can see the edge of her bra. Very realistic…that happens to me all the time in tank tops, and it’s nice to see it on the page. 🙂
after having just reread the archives Paul seems quite fond of that little slice of reality, it shows up a lot.
Hey..what the… My comment went up in smoke.. Was I too critical of audiophiles???? 🙁
Let’s try again:
First two frames are really funny. Dietzel suddenly realizes his beloved CD-player isn’t all that to be cracked-up about…
~Oooooh~ I get it.. Someone is removing the audio-chit-chat..
Seems logic..” ‘t went far astray from Wapsi-Square”
Let’s hope Dietzel doesn’t ever discover audiophile fora.. he’ll be hogging monica’s laptop for hours.
No comments have been removed.
One of my posts seems to have evaporated, too – and it seems to me that others may have gone, too…
Problem with the software?
I guess the switches had some bits falling over here and there.
(it used do drive one of my geekier collegues raving-mad when we explained an un-explained sudden drop in server-performance to inquisitive users by straight-faced stating that “a bit had fallen-over” 😆 )
Has anybody looked behind the server? There might be a pile of comments that got out through a loose connection or and open optical fiber or something…
Spring is in the air. The keyboard gremlins are migrating upstream to reproduce…
You DO know today is the apex of this months moon cycle, don’t you? It’s as full as it gets. Small wonder bits are lost, especially near the mid of the night.
That ^^ is a rather good explanation to use when New-Agey types call us about their VDI client being slow…
Oh, and by the by, this particular full moon is a “super”full moon because it will be closer to earth than it has been in 18 years. It will appear about 14% larger and about 30% brighter than usual at it’s peak.
I saw that. Quite cool. Overhere the sky was completely clear. It was an odd, but beautiful sort of twilight.
My like the leetle flowers in “What is it, Sweetie?” followed by the last panel glare. Yes that was a fake accent.
I can’t see anyone removing audiophile comments because they are relevant to the subject of the strip. A glitch, perhaps? I love today’s offering, though.
Oh Dietzel, I feel your pain. I had a high end CD player in my car, which when paired with the speakers I had upgraded to, made it seem like you were at a live performance. Then the front part got stolen, rendering the system useless. So when I got a cheap radio to replace it, it just wasn’t the same. Instead of being happy about having the ability to listen to music in my car again after 2 weeks, I was devastated.
Glad to see that Paul wasn’t affected by the gas explosion yesterday in South Minneapolis. I35 may be shut down for a while because of concern that the heat may have damaged support members.
There are some videos already…Damn! That’s a serious bit of fire. Cars seem to have melted in the vicinity O_o.
All snow in a 500yds – wide circle of it had melted due to the heat.
No casualties luckily, so I permit myself a quip: Who pee’d-off Bud??.
Alternately, Jin saw something. The other other cause is the interesting one; Brandi hasn’t talked about herself much in the comic, so we don’t what are her hot buttons.
Making Bud cry is one. This one and the next 8.
Thanks, Jabberwonky. That’s a good sequence, and I particularly like the waking-up-Shelly panel.
i believe this it…. some harsh comments, but very well recorded…
hm, bad enough to affect any site backup/update mechanism??
its possible that the explosion caused a slight emp to any nearby electronics…
but that’s probably just sci-fi nonsense from years of movie watching…
Nah, any EMP from that would be insignificant .. however, some of the towns powersupply could have been disrupted if they were generating electricity from gas turbines.
Also, if I’m reading Google Maps right, the explosion was about two miles south of places mentioned in the comic. That’s walking distance for an ordinary person, much less a teleporter. Do the Golem Girls shop at the Cub Foods at 60th & Nicollet?
Just for fun: http://www.uncommongoods.com/product/record-bowls
Heresy! On a related note, I was up on the top floor of Powell’s Books recently, and they had sketchbooks for sale whose covers were sawn from LP’s! I guess we should be grateful they didn’t all end up as landfill, but it seems kind of like that one rich guy (Hearst?) who made lampshades from medieval choirbooks. It just seems wrong, like burning a book.
Yeah, it was Hearst. This one http://www.pbagalleries.com/search/item145922.php?&PHPSESSID=eeb941 sold at auction for over 6 grand.
Hmmm. A disturbance in the Force?
…yeah, I didn’t expect that my comment would mae it through “moderation”….
I’m so glad I have a “tin ear.” I can listen to analog and digital without freaking out over one or the other.
