    Voice data just CAN'T be securely encrypted. That's because the spacetime information HAS to be there because we inherently interpret voice data according to these characteristics. Either you reveal this information in the stream, or you must increase the latency to the point that communication is impossible. If you want security, don't speak, WRITE, and use a cryptosystem that isn't a piece of shit.

    I disagree. The problem pointed at in this article can be easily solved on many SIP endpoints. I spend all day working on VoIP phones from vendors such as Linksys, Polycom, Aastra, Cisco, and if I really have to snom. Most of these have an option where it'll just send blank full bitrate audio rather than the usual "put silence here" instructions on G.711 calls. In fact that is the default behavior on some, since it makes the latency a bit more predictable to have a constant-rate data stream. If you want to use a VBR codec, of course this is a problem, but don't act like it's impossible or even hard to solve. If you are concerned enough to encrypt your conversations, use a CBR codec. 64 kbit/sec is not hard to free up.

  14. Re:Judging from the recent Unreal sales numbers on Unreal Creator Proclaims PCs are Not For Gaming · · Score: 1

    I disagree. I have a computer that was built in 2005 for under $1000. Since then I've doubled the cores (2GHz Athlon 64 to 2GHz Athlon X2), doubled the RAM (1GB to 2GB), and bumped up the graphics card, going from the GeForce 6600GT which was mid-range when I built it to a GeForce 7900GT which was mid-range when I did the upgrade. The total cost for those upgrades was under $500, bringing the total spent on this machine to roughly $1500 over three years.

    It still plays everything I throw at it without having to drop the resolution from the native 1680x1050 of my 20" LCD. Unreal Tournament 3, sure. Crysis, bring it on. It gets mostly used for Portal and Audiosurf, but it can still take more stressful games without a hitch.

    I just specced out a similar (slightly better, some of my parts are no longer in production) system on newegg for $555. AM2 socked Athlon X2 versus my 939, nForce5 successor to my nForce4 mobo, DDR2-800 vs. DDR1-400, GeForce 8600GT vs. 7900GT, TruePower3 550w vs my TP2, and Barracuda 7200.10 HD vs my 7200.8

    All except the video card should be within a few percentage points ahead of what my current machine has, I think the video card is a bit slower clocked but it has a newer generation GPU so if I remember correctly it trades off depending on the game. Older games are typically faster on mine, newer games are faster on the new one.

    Anyways, I can't see any complaints about needing a PC costing in the mid-three digit range to play modern games. Bumping up to around $1000 will let you future-proof it by going up another level in the CPU and graphics card, as well as doubling the RAM to 4GB (note that fully utilizing this requires a 64 bit OS, so if you can't stand Vista prepare to deal with the half-baked abortion that is XP64. Since we're talking gaming I'll leave the three major unixes out of the discussion...)

    When the Xbox 360 package that's actually worth buying runs $350 and the PS3 $400, I see nothing wrong with another $155 plus a bit of build time to have the option of better controls, higher resolution displays, and multitasking.

    Note that I am not a console hater, with the exception of the aforementioned Portal and Audiosurf my desktop PC rarely gets touched anymore where either my 360 or my PS3 are on pretty much every day.

    What I personally disagree with is Sweeney's whining about the fact that not every PC has a fast GPU. There are many uses for which you don't need to spend an extra $200 on a fast graphics card, compared to a chipset with integrated graphics.
    Actually, 90% of office PCs match that description. So there is a large market for PCs where a fast GPU would just be a waste of time. Get used to it, Tim... I think Tim's complaint is more that those PCs with integrated graphics are being advertised as having a "256MB* Intel Integrated Extreme 3D Graphics Accelerator" so the average person is tricked in to believing that their $250 Dell can actually play games which take more power than World of Warcraft.

    I look at it sort of like the Vista Certified thing where it's true that those computers _can_ run the game, it's just at 640x480 with everything turned off while still only managing 4 FPS. If the integrated pieces of shit weren't advertised as if they are actually useful for modern games, we probably wouldn't have this problem.

    If I had to compare internet telephony (and other internet services) to the standard set of traditional land-line TDM telephone service, I'd be tossing my desktop SIP phone (not to mention my cell phone) in the rubbish bin. If you notice a quality difference, your VoIP provider or internet connection sucks.

    I work in the VoIP industry where part of my job is fixing quality problems. Our standard codec is G.711u, which is the exact same codec used on the digital trunk lines in the traditional telecom system. Given the same input, the bitstream should be identical and thus the output on the other end will be just as identical. We can even go beyond that. In the traditional telecom world a T1 means 24 calls maximum, end of story. If quality can be sacrificed, I can drop the codec down to G.729 or GSM and fit 3-5x as many calls in the same bandwidth. Both codecs are roughly equivalent to a good cell phone (or exactly equivalent in the case of GSM since again it's the same codec).

    On the other side of things, we have G.722AB, which is marketed as "HD Voice" by Polycom. It takes up the same 64kbit chunk of bandwidth as G.711 but is a much more complicated design allowing for more than double the sampling rate and bit depth, thus significantly improved call quality. This can be used between compatible systems on private trunk lines, but you can't get the benefits when calling outside of your company without using VoIP. Calls in HD sound absolutely incredible, I was talking to someone in Chicago from Cleveland and it sounded like he was in the same room.

    VoIP does benefit from much cheaper long distance and international, but it also has a lot more flexibility than traditional telecom systems and if it's done right the reliability is equal or better. I have customers that have gone up to two years between problems, including internet downtime. Amusingly enough, I've found a decent cable provider to be more reliable than a T1 over that time. DSL brings up the rear, tied with some of the shittier cable providers.

    Obviously going from anything to a lossless format, assuming the new format is capable of handling the number of channels, frequency, and bit depth of the original, will be lossless as long as there is not a major failure somewhere in the chain as that is pretty much the point.

    What I'm saying is that with the exception of very simple lossy compression schemes if you go lossy -> lossy you will lose more data. In most cases the encoder has no idea what format the data was in previously, it simply sees the raw decoded output and whatever parameters were given to control the encoding process.

    Now, I will concede that there may be some tools designed specifically for re-encoding at a lower quality which work within the already compressed data to reduce the size with less or no impact from existing compression artifacts, but those would have to be designed specifically for a format and the efficiency of such a process would vary dramatically by the format chosen. The reduction in data will still cause more loss than if the original compression run had targeted that file size (as it could have optimized things better), but it could be better than just using the same compressor over again.

    Maybe if we're talking something like simple audio compression (I think G.711u as used in the telephone system counts here) or dithering to 256 colors for GIF compression where it just drops off data that doesn't meet certain requirements...

    If I save an image as a JPEG or an audio file as MP3, artifacts are introduced. If I then save that file back as a PNG or WAV, it's now in lossless form but it still has the artifacts and missing data. When I then go back to save it in its respective lossy format, now the compressor has to deal with the artifacts and in the process introduces new artifacts as well as discarding more data to make room for the data describing the previous artifacts.

    Transcoding from one lossy format to another or even re-encoding with the same encoder is as bad as if not worse than copying analog tapes in terms of quality loss. The first one will usually be reasonable, the second bearable, and beyond that it just goes downhill dramatically.
