SanDisk, Music Publishers Push DRM-free SlotMusic Format 368
Strudelkugel writes "The LA Times and others are reporting the music industry is working with SanDisk to try unrestricted music files on microSD memory cards to improve sales of physical media: 'In addition to music, the slotMusic cards will come pre-loaded with other things, such as liner notes, album-cover artwork and sometimes video.' The important part: 'The music on slotMusic comes without copyright protection, so it can be used on almost all computers, mobile phones and music players — but it won't play on an iPod, which doesn't have a micro-SD memory slot. It has one gigabyte of memory, and the music tracks are played back at high quality.' Could it be the labels have finally recognized that providing features and convenience to customers is preferable to suing them?" Most computers also don't have microSD slots; according to EMI's press release, there will be a "tiny USB sleeve" packaged with each card, and the "high quality" format means up to 320kbps MP3. From the given description, it seems like it would be no harder to transfer the tracks to an iPod (via a computer) than to most other players.

you need different ranges assigned to different speakers that can give out that frequencies. but, there has to be more of the same speakers assigned to a particular frequency range - lets say, you got a certain size of tweeter. if there are 4 of this, and you divide a small incremental range of high frequency sound to four of these in small increments, you'll have, say, seperated two sopranos' (each soprano will have differences in their frequencies, even if minute and hardly identifiable by human ear) voices to two tweeters of the SAME kind, but while playing these two sopranos' voices, each of their voices will come from the different tweeters. this will increase the distinctiveness of each sound. here, the quality of the tweeters matter VERY much.
just like tweeters, if you have many mid range speakers to assign incremental frequencies, the clarity of sound will increase.
people generally err in that if there are 5.1 speakers, or 7.1, you can do more of that, because there are more speakers - that is not the case. in almost all 4.1 and more speaker systems, the satellite speakers generally come with the same size, therefore being able to effect efficient and clear playback of a certain frequency range. whereas it is good for positioning through different channels through software, it is bad for music quality and sound clarity - because you will have to play a broader frequency range from that speakers.
also, positioning does not matter much when playing music - think - how many times were you able to sit in the middle of a symphony orchestra, or a rock band in concert, and listen to music ?
not only you cant, but also it doesnt make any sense - human ears are directional - you wont be able to hear the sounds coming from the back as distinctively and clearly as the ones coming from an angle from the front.
that is why all music concerts, gigs, playback and whatnot are done in front of the audience.
a stereo setup correctly reproduces that positioning. ie - your hearing field is like a letter 'V' while listening to a concert, your head, field of hearing starting from the bottom end of the V, and the arrayed speakers of the concert setup being placed in upper tips of the V.
in concerts array speakers are used. if you paid attention, there are a lot of speakers positioned in the same place to the right, and left of the stage, on top of each other. this creates a sound stage that encompasses you.
this concept was a niche concept in which only audiophiles knew and were able to use. because mainstream stereo producers were just skipping by it. we didnt have any chance of listening to such stuff on a pc speaker set at all. however altec lansing made a good entry with such a product a while ago, and it changed the way all the speaker system producers designed the speaker sets. see altec lansing fx 6021 here : http://www.alteclansing.com/index.php?file=north_product_detail&iproduct_id=fx6021 [alteclansing.com] notice the 'in concert' technology, and notice how similar speakers are arrayed on top of each other. Read people's thoughts on this thing here : http://www.amazon.com/Altec-Lansing-FX6021-Speaker-System/dp/B0001EMLXE [amazon.com]
this thing, is supposedly a pc speaker set. it should be nothing significant. but, when i bought this, it totally ousted my full deck pioneer stereo with $700 speakers each. i stopped listening to anything else.
one of my friends took this choice lightly, and went for a X.1 system from a known manufacturer, but after a while he decided to get the 6021, but he wasnt able to get one because it was out of stock. he is still looking for one since then, and its on the top of his list. he spends $350 on motherboards alone, when doing an upgrade.

Stereo, for example, was invented to create more space for sounds in a recording.
No, it wasn't. Stereo is used to recreate the spatial component of music: when you record a number of instruments sitting at different positions in the studio, you should be able to hear where those instruments are. That has nothing to do with 'too many waveforms ...cramped together on the same output'.
In fact, in a stereo recording, most of the information will be played back by both speakers.
It is possible to make a recording where the left and right channels have nothing in common, but you'll find that those sound very unnatural, so these recordings are (thankfully) rare. It's like having half the musicians on the far left of the stage, and the other half on the far right, with nobody in the center.

Nonsense. No audio system works like that.
1. you can't separate two voices or two instruments like this, because each voice produces a range of frequencies that mostly overlaps. They'll sound different because their harmonic spectrum (the relative volume of each harmonic) differs a bit, but there is no filter that can separate them.
2. A loudspeaker box usually contains a few drivers of different sizes, because the driver size needs to be matched more or less to the frequency. A 12" bass driver is too heavy to produce 10 kHz, conversely a 1" tweeter can't move enough air to produce convincing bass. The challenge is to use no more drivers than necessary, because dividing the frequency spectrum like this introduces all kinds of problems. The holy grail of loudspeaker design is the point source: a single point that can produce the entire spectrum.
The only reason loudspeaker arrays are used, is volume. Multiple parallel drivers can produce more volume than a single driver.
There are some interesting side effects to arrays. The dispersion pattern changes a bit, which can be beneficial if done right. But 'a sound stage that encompasses you'? No. That's due to the surfeit of power which sets up reverberations in the hall. You get the same effect cranking up your non-array home stereo.

Well, it might not be the reason stereo was invented for, but it is definitely a side effect of stereo's existence.
I've mixed a lot of recordings, and can say from experience that separating instruments into different speakers (not 100% panning, of course) will definitely reduce distortion.
Of course almost nothing is panned all the way to one speaker, but basically when you pan something 70% to one speaker, you reduce its volume on the other speaker significantly, thus allowing more sonic space for other sounds on that speaker.
It's something that can be easily comprehended when playing around with a recording's mix.
Plus, it's a good way to avoid "clipping" - a signal that goes over 0dB and gets distorted. You can separate the recording into different speakers, and thus the overall volume on one speaker is divided between the others, and neither speaker goes over 0dB, and you avoid clipping distortion.

You cannot hear the difference between a 16-bit recording and a 24-bit because in 16-bits per sample the SNR already is 96 dB. There's nothing a sampling frequency higher than 44.1 kHz will bring you since you cannot hear anything above 22 kHz.

There's something else that matters, namely the distance between your ears and each individual tweeter. If the distances are slightly different, certain frequencies will be amplified, others will be cancelled out. This is inevitable, since crossovers are not infinitely steep and therefore multiple tweeters will play the same signal, which will then arrive at your ears at different times. This may result in you perceiving the sound as clearer, but actually isn't really desirable. An Ideal loudspeaker would be a point source that emits all frequencies.

Actually this is non completely impossible. Using special DSP techniques (adaptive filtering and SVD) a digital system can try to decompose a stream into several sources. This doesn't work perfectly, e.g. if the two sopranos would be producing exactly the same sinusoidal tone, they cannot be isolated. Similar techniques are being used in hearing aids (not talking crap here, I worked as a phd student in a DSP lab where similar things were being done).
This aside, it is indeed impossible to do such separation using only analog circuitry, let alone just speakers. The only thing that comes close is when the recording was done using multiple microphones. In that case some analog processing (beamforming etc) may separate different voices on different tracks, and the audio field may be regenerated using multiple speakers.
I don't understand why such an obvious false claim (by the GG..GP) is modded up.

"But pretty much anyone with decent equipment *can* hear the difference between 24bit and 16bit, or 48khz and 96khz."
Lots of people who pay large sums for audio equipment _claim_ they can hear such differences despite the fact that the original source signals from the best microphones in the world don't produce any useful information above 22KHz and have signal / noise ratios of 90db or less, so there won't be any extra musical information that requires the higher frequency response and dynamic range provided by more bits and higher sampling frequencies.
Studios use high sampling rates and word sizes (192 KHz 32-bit) because multiple tracks can act as input to other tracks, which means that noise accumulates, and positional differences of high frequency bits in lower sampling rates can combine to produce artefacts (both of these can and do also occur when mixing multiple tracks down). Neither of these is a factor in domestic listening however, because _any_ system below the native studio resolution of 192 KHz 32-bit will end up being dithered down using the same algorithms (often on the same hardware).
"That is a pretty well established fact"
Established by whom? Double-blind listening tests indicate that there's no objective difference between them on any level of equipment when they're only being used to play back pre-recorded sources, irrespective of the musical genre being used to evaluate them. There's plenty of psycho-acoustical information to indicate that rise-times in waveforms above the upper threshold of human hearing can have a notable effect on the way it's perceived, but the inability of microphones used in music recording applications to transduce those frequencies into useful signals means that it's of academic rather than practical interest (some microphones such as the ones used in bat detectors can respond to extremely high frequencies, but they have other characteristics that make them useless for recording music signals).
"Audio CDs are generally encoded as 48khz, 16bit, 1411kbps PCM audio"
The audio on digital video is recorded at 48KHz. CDs are 44.1 KHz.
"For comparison, get one of the few albums available in DVD Audio and compare them to the CD - especially at high volumes. "
You'll need one of the even fewer DVD Audio albums that isn't up-sampled and re-mixed from a 44.1 KHz 16 bit master, and therefore actually has some chance of containing real extra musical information that isn't on the CD version to make such a comparison valid, otherwise any perceivable differences will be nothing more than artefacts of the up-sampling and re-mastering process.

It's the INPUTs! Having mixed a concert or two in my day, I can attest that there is a very big difference between the controls I have available at a mixing console and what I can do with previously-recorded music.
Consider a concert setup: EACH channel is the input from a single microphone on stage. There is no need to separate one singer's vocals from another; they are already separate! See: mixing console [wikipedia.org]. Want the lead vocalist to be a little louder? No problem! Just boost the volume for THAT input. S/he is standing left of center? Adjust the pan and send more of the mix to the left output than to the right.
That kind of MIX is what gets put together and recorded to a CD. And once it is put together, it's much harder to get everything separated back again. That's why the mixer has all those separate inputs to begin with.
As to why there is an array of speakers, that's another matter. We had two active crossovers that split out low, mid, and highs that came out of the mixing console. One for the left and one for the right. From the active crossover, the bass went to its own amplifier which, in turn, fed the bass bins. The mids went to their own amp which fed the horns. Lastly, the highs went to its own amp which fed the tweeters. IIRC, we used a 300W amp for bass; 200W for horns, and 80W for the tweeters. On each side.
That kind of setup allowed us to use the speakers best able to reproduce certain parts of the audio spectrum and feed them the amount of power they needed. If we suddenly had available a larger venue, we could have taken the same mix as input, replaced the amps with more powerful ones, and added additional speakers.
