    Yes, but if you plug your Gibson into a roaring Marshall stack or Boogie dual rectifier, it's intentionally being distorted insanely much- meaning that suddenly, the brush of a feather across the strings is slamming your head into the wall.

    Try it yourself- alternate between live guitar into a good, utterly cranked amp, and the output of your PC with a digital recording of your guitar. I think the odds are that the difference will become huge, because that much distortion drags out the slightest weakness in the sound.

    I dunno. The thing is, you only need one person to do the heavy lifting, and then it's in the GPL sphere and can be taken from there when needed.

    My own perspective is from pro audio- specifically, mastering. You might say that you wouldn't see open source people do serious stuff in wordlength reduction or mastering processing, except that it wasn't- the person who did serious work in wordlength reduction wasn't 'open source people', it was me. And I suck at coding, am miserable at file handling, but got the basic algorithms down- in the pure GPL sphere. Enough people know about that now that it can't be taken away...

    On the basis of this experience I'd suggest that what will happen is not OSS coders _learning_ to do 3d, but instead some iconoclastic 3D coder, possibly one with poor coding skills _outside_ of the central problem, will throw together something that works because _they_ believe in the concept. It's gotta be an insider rather than a coder project meant to meet a goal- but it may still be somewhat 'hobbyist', for instance it might be directly comparable in output quality but not capable of pro-level workflow (that's what bit _me_ with my own project). But there's likely to be something- possibly even soon. Whether you'll hear of it is another story because it'll be done by a person or people who are primarily geeking out on the project because it interests them and meets their immediate needs- publicity comes much later, if at all.

    I've done something vaguely like this in the GPLed version of Bungie's Marathon, "Aleph One", by setting up a vast plain with a couple hundred enemy aliens on the other side. You get a whole stockpile of arms and when you wake them up, they charge you en masse.

    It's not all that fascinating as there's only 20-50 enemies in your immediate vicinity at any given time. Most of the fun is firing big ol' weapons into _crowds_ of enemies. They can't be projectile-using enemies or you're just hosed instantly ;)

    I guess it _is_ a disappointment, after all.

    I had my heart set on it being a twin-turbine personal helicopter :) funny thing is, I had this all worked out to the point where you could damned near build one, all on the basis that Steve Jobs et al wouldn't be fools enough to go ga-ga over a powered scooter.

    I'll give 'em this much though: yes, designing cities without cars WILL eventually be necessary. Yes, that will be interesting and challenging and different. But I thought it had to be a lot more exciting, and pulled together loads of detail such as recent developments in titanium production, the capacity of (highly efficient) jet turbines to route their intake and exhaust in very counterintuitive ways, the geometry of a twin-ducted-fan standing platform and how this would be essentially stable and would require hard leaning to get it to move quickly- and even then, wind resistance on the high-mounted fans would mean that the machine would be trying to slow itself at all times, its CG located very low because a human would be standing on the base and their CG would be irrelevant, the orientation of the device would follow the centering effect of the human's weight delivered through the feet...

    The only thing even vaguely like this would be the SoloTrek, and just think for a second of how much heavier _that_ monster is than a person- it's really just a mini helicopter, not even the balance issues would apply. As such, so much of its awful power and noise etc. is required simply to lift its own weight, and how much better it would be to use titanium and minimal, balance-oriented controls to make something so feather-light that it's barely heavier than a person, far more capable of urban use...

    To top it all off, turbines are ideally suited for just _one_ speed, which is an ideal match for a heli-type device as it would be devoting pretty much every bit of its energy just to hovering, with no engines whatsoever for lateral motion- that would be strictly a matter of leaning in the desired direction like you were in a hang-glider. All this is just _waiting_ to be done, and Kamen has the resources to do it _and_ a background not only in aviation but in helicopters. It seemed so obvious.

    I'm in the middle of reading a Robert Heinlein book, the 'Expanded Universe' collection. In it are his reports on visiting the Cold War USSR as a tourist.

    Your advice is apparently EXACTLY what you had to do to not be blatantly lied to and jerked around as a tourist to the Cold War USSR (i.e. around 1960). Having read his articles ("'Pravda' means 'Truth'" and "Inside Intourist"), I can also expand on your advice in a useful manner:

    Feign losing your temper, but do not actually do so. Don't lose control, remain in control at all times, but behave as if you are losing your temper. Don't allow yourself to be moved away from the front desk/cash register, you must block other customers until you are satisfied and get what you want. If you allow yourself to be moved so you're not in the way, you lose: you're off the game board and can expect to be lied to at length in some nice little office but you won't get what you wanted because you're no longer causing a problem, just an inconvenience.

    Also, try to remember that the first line of defense against you are likely poorer than you are- they're helpless functionaries, cash register operators with no influence whatsoever, and they don't personally deserve your anger, they are just part of a system designed to rip you off. This is another good reason to feign anger rather than let yourself really be angry- it's not right to take out real anger on these people, they have no power at all and will probably have a horrible day as a result of your feigning outrage and anger. Unfortunately you have to go through them to get to a higher level where you might possibly get close to what you want, or what you legitimately paid for.

    Now... having relayed this good advice from Mr. Heinlein, I have one question.

    How the hell is it that we, in the USA, are reduced to using techniques Heinlein was driven to using in the freaking Soviet Union under Leninist Communism, just to avoid being ripped off and cheated?

    He was convinced the USA would collapse before 2000. I'm not so sure he was wrong... and I'm damned glad he didn't live to see this.

  14. Re:"Infinite Resolution" my goatse.cx! on Linux-Based Audiophile CD Archival System · · Score: 2
    It sounds like you're being confused by dithering :)

    Indeed you have to add 'random noise' or at least SOMETHING to decorrelate the quantization distortion. Done properly this allows you to return SIGNALS well below what one would consider the theoretical limit of digital- for instance, in a heavily noise shaped dither I did that hit -160 db at the very lowest frequencies, I was able to test this and return a measurable result for a tone at -156 db beneath digital full scale, using only 16 bits. This is normal and proper use of 'noise' to resolve signals below the quantization threshold, and you can look at it as a statistical thing- it becomes possible to 'average' a signal voltage that in practice falls between quantization values, as long as it's bandlimited and you don't expect to be able to do it at near-Nyquist frequencies.

    However, if you add noise _after_ quantization, the damage has already been done and it doesn't matter how much other noise you add- it won't help. It can only decorrelate quantization errors if the noise is put in before quantization- and the only way you can get a 12 or 16 bit recording to sound like 'analog' (I assume we're not talking telephone answering machines here?) is to address the quantization problem- and dither, and ideally do noise shaping as well.

    So... I'm claiming in turn that yes you can bring digital sound closer to analog, but the function of the noise _must_ be prior to quantization, and it is not 'degrading' the sound unless you think strictly about sample-to-sample accuracy. As soon as you start to consider bandlimited sound the random noise takes on its additional importance as a method for statistically approximating signal values of higher resolution than the direct quantized values.

    And, if you put random noise on the digital sound _after_ you quantize, you just lose- it's not going to sound anything like analog, it will just be worst of both worlds- correlated noise _plus_ worse noise floor. You don't get anything close to analog-like behavior by just adding extraneous noise, even though analog does contain extraneous noise. You have to get the linearity right first, otherwise you're wasting your time...

    Yeah, but try to _compare_ a vinyl record with the 12 bit recording that you think is comparable to it. I will give you this: you'll need to be using some sort of acoustic sound somewhere in the recording, preferably with some room or hall ambience. That's not hard, though- and in practice, the record will seriously humiliate the 12 bit digital recording.

    It'll be more difficult to humilate a 16 bit recording, and still more difficult to humiliate one reduced to 16 bit from higher resolution using advanced wordlength reduction technology (like any of the high energy noise shapers that produce a noise floor dip around 3K).

    You would not believe how difficult it is to get a CD to perform comparably with even an ordinary vinyl record in the resolution domain. Take it from somebody who writes (open source) digital audio dithering software: the resolution domain is potentially a horrible weakness in CDs. It CAN be overcome with exceptional dithering and careful handling of the digital signal throughout, but it usually is not.

    What you're hearing when you hear CD as 'purer' is really the drying up of low level detail, particularly in the 3K area where the human ear is most sensitive. Vinyl has high but frequency-localized noise levels and is quite capable of higher resolution performance AT 3K, where the ear is particularly sensitive.

    A CD really done properly doesn't sound 'pure'. It sounds convincing, and juicy/reverberant/lively/etc depending on the source material. Real world sounds don't sound 'pure' in the way that CDs do- that is a side-effect of a noise floor that is very different in character from analog noise.

    Do you get to pick your choice of WAV (or AIFF)?

    I could set you up with either a master that was indistinguishable from even 128K mp3, or one where you could tell it from even 320K blind every time.

    For the latter- do a minimalist recording in a good hall, and listen specifically for soundstage depth. ATH level and psy model go straight for the reverberant field and throw most of it away. If ATH level's not up to the task you get a very shallow soundstage or a total drying up of reverberant information. If psy model is in effect you get twice as much of this, and it's got a weird unnatural quality. It's brutally hard to get soundstage depth out of an mp3, because if you have ATH threshold TOO low, the whole mp3 is used up trying to encode reverb information and sounds horrible and muddy.

    For the one you can't tell between a 128K mp3- well, you could just do a lot of digital gain tweaking all on 16 bit busses for the maximum quantization error and coarsening of the sound, but if you think about it, it would be even more effective to just make the WAV the decompressed version of a 32K mp3 ;)
