    I agree that compressing the final track sucks, for multiple reasons. You should never do much (if any) dynamic compression after mixdown, as it tends to result in odd problems where the drum hits cause your vocals to sound different.

    That said, you can get the same level of loudness by doing heavier dynamic compression on the individual tracks. The most important decision is choosing the right amount of compression, rather than choosing whether to compress on the way into the mix or on the way out. :-)

    If you did the "loudness war" thing with an LP, the stylus wouldn't track.

    I don't know why people think this. The loudness war didn't make the loud parts louder. It made the soft parts louder. If anything, the more consistent excursion should make it easier to adjust your hardware.

  5. Re:Useful for audiophile pirates, though on Music Pirates Won't Rush To iCloud For Forgiveness · · Score: 2

    I couldn't disagree more. Uncompressed music works fine for a very thin mix (e.g. guitar and voice, piano and voice, etc.). Add in drums, and it sounds like ass without compression unless you're listening at 24-bit resolution. The tops of the peaks for drums are so high relative to the area under them that you blow all your dynamic range on them just trying not to clip. The result is that everything sounds weak and distant.

    Now I'm not saying today's music isn't massively overcompressed dynamically, but it's just as bad to undercompress stuff that needs it.

    BTW, LP audio can be just as overcompressed as audio from any other source. They just tend not to be because anybody doing a vinyl recording is likely working from an analog tape master that already builds in some tape compression, because they are mostly older recordings, and because there is no consumer demand for them to be so compressed. (More on this later.)

    More to the point, your comment about overcompressing to vinyl breaking the vinyl is just plain backwards. If you don't compress audio enough when going to vinyl, it won't play. There's only so much loudness you can achieve on vinyl before the cutter excursion is too great and it breaks through into the next track over. And you have to leave a certain amount of wall thickness between tracks, or else the needle will break through while you're playing the LP. This means that there is an absolute limit for maximum loudness on vinyl (at least for any given duration and RPM setting).

    Add to this the baseline noise caused by mechanical imprecision during the cutting process, and you get a typical SNR of about 60-75 dB on average (Source: itrax). And many albums have even lower SNR because if they compress the audio more and lower the maximum volume, they can cram more tracks per side. Thus, if we're talking about the ability of the medium to reproduce the sound, LPs must be compressed more than CDs, not less.

    In short, the only reason CD audio tends to be worse than LP audio is because the industry thinks people want to listen to music that way. And unfortunately, with the number of people listening to music in cars or on iPods while walking around loud city streets, they're probably right. People who listen to music in an environment that lends itself to high dynamic range are, unfortunately, a rarity, and modern digital music production merely reflects that unfortunate reality.

    That said, I'd really like to see the overcompression moved into a special hint track and implemented by the player instead of permanently marring the sound. This would require some significant retooling, but it's not inconceivable. Alternatively, provide two separate mixes: a high compression track and a low compression track. Either solution would let the audience decide when they listen rather than when they buy the CD.

    Actually, there is no evidence that a free market will help. In every non-urban area I've seen that has allowed additional telcos or cable companies to provide service, the result has been the same: the incumbent carrier, whose lines are long since paid for, undercuts the new carrier to the point that they cannot make any money. The new carrier goes under and sells their lines in a bankruptcy sale to the incumbent carrier, the backers of the new company get screwed, and the incumbent carrier gets a free infrastructure upgrade. Then, they raise rates above where they were before.

    Last-mile infrastructure is expensive. Except for large cities, it isn't feasible for anyone other than the government to roll it out. This is why the government provides grants and tax breaks to subsidize the construction of last-mile infrastructure. The only feasible alternative to this that has actually been shown to work is government construction and maintenance of the relevant wire infrastructure. In places where the government owns and maintains the wires, free market competition tends to work very well among the various ISPs that lease access. Those ISPs need only provide blocks of IPs, routing infrastructure, and upstream connectivity from a central office. This makes competition much more feasible than having hundreds of companies trenching your yard and laying cables.

    Unfortunately, the vast majority of people who realize that there is too much government intervention for the free market to operate are also the same people who oppose any government-run wire infrastructure projects (because that would be increasing government interference in their minds) and thus actively thwart the one solution that would actually allow the free market to operate in any useful way. As a result, with the exception of a few very rare, forward-thinking communities, telecom in the United States is a train wreck in slow motion, with emphasis on "slow".

    If it were about safety, the cameras would go into places where your safety is most likely to be compromised.

    No, if it were about safety, they would not be putting up cameras at all, but rather would be doing the one thing that has actually been proven to reduce red light violations: making the yellow cycle longer. Instead, they put in cameras to raise revenue, then make the yellow cycles as short as they can to maximize revenue. They also write tickets for provably safe violations like a rolling right turn just as the light turns red. And so on.

    Want to improve road safety? Raise the minimum yellow cycle length to 7 seconds, or 10 seconds on roads with speeds of 40 MPH and up. Add a countdown timer above the light in large numbers that tells how long before the light turns red. Finally, add a minimum two-second all-ways-red cycle before the light in the other direction turns green.

    It's about like the county Sheriff in Cupertino, CA ticketing people as they "jaywalk". It's a highly traveled corner, and despite not having a true pedestrian island, there are places that a pedestrian could go if they get stuck in the middle. People therefore walk halfway out while the left turn light is on. This allows them to be halfway to the other side when the light turns green. This is provably safe because (ignoring people turning right on red) no vehicle can legally cross that pedestrian crossing at that point in the cycle. In short, it's pure revenue generation.

    And they ticketed my boss for not stopping long enough at a stop sign. The guy claimed that you need to stop for a full 5 seconds. If I stopped for 5 seconds, the people in the other direction would assume that I was yielding the right of way, and they would start driving the moment I did, and we'd probably have a wreck. I guarantee that the cop wouldn't have spent five seconds at that corner.

    Ultimately, what needs to happen is this: police should not see one penny of traffic ticket revenue, and neither should cities. The state is licensing drivers, so the state should collect all of the revenue, and should distribute it proportionally by population. That would eliminate the incentive to write tickets for things that are not truly unsafe, and more to the point, would eliminate the incentive to reduce yellow cycles to unsafe levels to increase traffic camera revenue.

    Well, ex post facto laws and bills of attainders are interesting, but they do not apply here.

    An ex post facto law would retroactively make it illegal to have performed or sold copies of a work during the time in which it was out of copyright. This law change did not do that.

    Similarly, a bill of attainder is a bill that declares someone guilty of a crime and strips them of rights without a jury trial. This only does half of that, as it does not declare them guilty of a crime, but merely deprives them of property (IP rights) and grants them to someone else. That somewhat narrower right has been upheld in SCOTUS decisions before, with Kelo v. City of New London being the canonical example.

    It's actually the fourth amendment that applies here, not the ex post facto clause, nor the bill of attainder clause. What this law changed was future use of the work. This means that copies of the work that you recorded while it was not under copyright can no longer legally be sold or performed.

    By any reasonable interpretation of the fourth amendment, this is an unwarranted, unreasonable seizure of property (intellectual property rights) held by thousands (if not millions) of people. Your right to continue to use sheet music that you own (music that you are physically in possession of) ceased to exist when this law was passed. Your right to play CDs, tapes, DVDs, and LPs that contain recordings of this music no longer exists. Your right to sell recordings of these works recorded during that era no longer exists (whether you are the performer or someone who previously acquired a copy) because doing so is considered criminal commercial violation of copyright.

    In effect, the government came and seized every copy of this music, not by court trial, not by armed infiltration, but by signing a law. And afterwards, they gave that property, not to the public, not to a private company or individual for public use, but to an individual with the intent of preventing existing public use and extracting money in exchange for future public use. That's contrary to both the spirit and the letter of the fourth amendment by any reasonable standards. And that's the key to understanding why this case is neither like Eldred v. Ashcroft nor Kelo v. City of New London.

    My point was that nobody implements password handling like this because that creates a trivial avenue for denial of service for the account. All I'd have to do is have a botnet of one computer trying five passwords every 15 minutes, and you would never be able to log into your account ever again. I don't need to know your password at all to permanently deny you the use of your account. I need only to learn your username.

    Instead, what everyone actually implements in practice is five attempts per 15 minutes per account per IP. So if you have ten million distinct IPs, you have fifty million password attempts per account every 15 minutes, 200 million attempts per account per hour, 4.8 billion attempts per account per day. That's 1.44 trillion total attempts per day, assuming the computers and networks are fast enough to handle this.

    The smarter companies implement a limit per IP per unit of time as well, which tends to lower that number considerably.
