  1. As a hobbyist sound guy... on Mastering Engineer Explains Types of Compression, Effects On Today's Music · · Score: 5, Interesting

    Y'know, there's always someone harping all day long about how MP3 takes a steaming liquid crap all over your sound, and I cannot agree with them. I have a mid-range yet respectable sound system, worth maybe $4000 new. I listen to a LOT of music with an unforgiving ear for detail, and what I often joke as "digital audio memory". Anytime I listen to something, I'm comparing it to a very precise memory in my head. If the pitch is off by a hundredth, there's subtle (dynamic) compression, or phasing issues, I know immediately.

    Back when we were peddling 112 and 128kbps MP3s (y'know, 15 years ago), it was pretty obvious that our encoders sucked. You could hear the nasty phasing all over the high end. Today, with most dedicated rippers using "LAME -V0" or 256/320kbps CBR, I'll say that it is impossible to tell the difference on 99.9% of all music out there. Yes, you theoretically lose some high-frequency information above 19khz, but hardly any adults can hear those frequencies anyway, as our range of hearing degrades with age. At 32, I have supposedly great hearing, yet I can barely hear 18khz, and 19khz I can't really hear but just "feel" as pressure on my ears canal. The parts MP3 encoders discard, most people can't hear anyway, and even if we could, it's so high in the audio spectrum that it's just headache-inducing whine. In practice, many mastering engineers will filter that out anyway, because those frequencies are nothing but trouble, they can mess with playback on cheap (read: common) stereos, and are basically a waste of signal which could be better allocated to the mids.

    The compression artifacts themselves, they are nothing like they were 15 years ago. If you really want to see how much sound is lost from compression, take an uncompressed WAV, convert it to MP3, then back to WAV. Pull a spectrogram for both the original and processed WAVs, and compare these in a graphics editor. If you're lazy, you can grab the screenshots from here instead. If you're using photoshop, change the blending mode to "Difference" on one of them. Any coloured pixels are the differences, while black means both images are identical.

    So, that's digital compression. The other big thing audiophiles bitch about is dynamic compression, and that is an all-too real problem. This is the "brick wall" sound people often cite as the cancer that's killing music. It is the process by which quiet sounds are made disproportionately loud, resulting in the average signal level being louder across the entire album. Most common audio is stored as 16-bit data, this means there are 65536 different intensities available, from silence to maximum, across what is often quoted as 96dbfs of range. Most modern pop music crunches all the sound into the uppermost 6db, so you're kind-of getting 1/16th of the fidelity (yes my math is flawed). This makes crappy speakers and earbuds sound "better" (still shit), and good speakers sound equally shit. It's the sonic equivalent of turning the brightness and contrast on your TV all the way up, now everyone has bright red skin and look like cartoon characters. If you want a painful example of this distortion, cue up Metallica's Death Magnetic, the official CD or iTunes version. Then go find the Guitar Hero version of the same album on TPB and compare. The pressed version is brickwalled, the Guitar Hero version was mixed much more reasonably, in-line with past Metallica releases. Then if you want to hear the opposite, something with very wide dynamic range, try ZZ Top's Eliminator, or Van Halen's 1984. Björk's albums also tend to have good characteristics. You're looking for quiet sounds amid the louder ones - they might be the little squeaks of guitar strings or drum skins, or the long fade of a cymbal.

    Back to our buddy boy Ian Shepherd... one of his recommendations for good dynamic range is Daft Punk's Tron Legacy soundtrack. This is pretty much an admission that the man is completely full of shit. Don't get

    It could have been a geographical thing too, but by 1996 we were starting to get DSL and cable internet in my area. We had municipal projects to get people on the net, and they were hiring students all over the place to build the web site and write content. By 1998, I was in the hosting and design business, convincing local businesses and malls to let me build their web site.

    Not at all. That was just the "mystery customer" call to confirm the shenanigans, after several users complained about it to Avast.

    After RTFA (*gasp*), my interpretation is that iYogi is pretty much attempting customer fraud, by running bogus diagnostics and selling expensive solutions the customer does not need - and dare I say, probably won't fix anything besides the fake alerts. Over here in Canada/U.S., that's a serious offense that can land you in jail. I don't know how India's criminal code relates, but even from a purely business perspective, iYogi is still defrauding its client, Avast, as they are spending their client's time and money to convince users to fall for a fake diagnostic scam. That's a very good reason to terminate the contract, and then sue the company.

    Now I guess the question becomes: how hard is it to sue an Indian company into the ground ?

    For me, that's exactly how it played out. I'm a programmer, I need a beast of a machine with a good keyboard and tons of display real estate. The only time I ever use the tablet is for playing Angry Birds on the crapper.

    For my wife though, the tablet is her new PC. She uses it almost exclusively, because it does 99% of what she needs from a computer: surf the web, play dinky little games, read email, stream youtube. The other 1% is when she needs to edit a real word doc or print something for work.

    Thing is, there are a lot more non-tech users like my wife, for whom a tablet is enough "computer" for their needs. This YBUY thing could take off, but then again, if you want to try an iPad, you can go to any Apple store and play with the demo units. The YBUY service might be more for people who want an iPad, but only for a week or two (e.g. trip or business demo). In my case, I could rent one to test an iPad app I'm developing, because I don't do enough of that kind of work to justify spending $600 on one.

If I.T. didn't work out, I could easily have become a mechanical engineer, chemist, architect or any number of brainy careers. For people who aren't so blessed between the ears, whose job options are much more constrained, I can very easily see why they would choose a life of crime. If I were in their shoes, I'd do the same. Why make $11 an hour at Wal-Mart working for assholes when you can make $1000 a week, tax-free, slinging party favours at the club ? Or what about the taxi driver who sells a few cases of beer after hours to double his income ? I cannot easily fault these people, they have been backed into a corner and are doing whatever they can to make it in this greed-obsessed world. People are not born criminals, that's just a label.

    15 years ago, we were up in arms with WinModems, because these did not work in Linux. Why ? Because instead of implementing a serial interface and their own hardware DAC, they were little more than sound cards with an RJ11 jack. This moved the burden of encoding the audio stream to the host CPU, and why not ? It resulted in much cheaper modems due to ditching an expensive and license-burdened encoder chip. Linux had to catch up, but instead of doing so, people bitched and moaned all day long.

    Printers and winmodems do not require the Windows OS. They require device drivers that go beyond what we were doing 15 years ago, but that's where Linux is right now.

My gripe is that the layout system itself feels extremely immature. Sure, you can design with weights, but proportional layouts simply do not work well on with grossly divergent aspect ratios. When going from legacy 320x480 smartphone to a 1024x768 tablet, scaling does not cut it, you need to reflow elements or even completely change the UI to better suit tablet users, and that's where I find the Android SDK drops the ball. Tablet support was hastily tacked on as an afterthought and it really shows. I usually have to create a largely separate code path for the tablet sizes, with their own layouts, so the result is essentially two different apps packed inside the same APK, with a handful of shared non-UI classes between them.
