Excuse me, but that's comparing 2 entirely different encoders. AAC+ is designed to sound good at very low bitrates, and is used in applications like terrestrial digital radio broadcasting. OGG Vorbis has no such optimization. I can't see how you couldn't tell 56k from 26k, assuming you were referring to MP3. Most people have trouble tellign the difference between 128k and higher bitrate MP3s on average cheap hardware, but 56k sounds like total poo poo no matter what it's on, except for purely spoken word content.

You don't really have the same thing for audio, especially 2-channel. There are objective standards for audio - do a simple double blind test or hook up an oscilloscope or something and check against a reference signal - audiophiles just absolutely refuse to use them.

Then you don't know what you were talking about because you brought it up for when digital signals are transferred between two devices over an analog carrier. And by the way if a digital signal doesn't vary it's carrying either all 1s or all 0s.

Spoondrift posted:Dude, really? Do I have to spell out what I mean by "variations in a digital signal" so you don't egregiously misinterpret me? And any device you buy that's legitimate is designed to handle minor variations, and (almost) all digital signaling systems involve some form of error-correction. It is very difficult for a digital signal to spontaneously become a valid, different, signal, instead you just have drop outs in video/audio or somewhat degraded quality for a few milliseconds. Furthermore it'd be extremely difficult to build a DAC that only accepted a precise voltage for 0 and a precise one for 1 - most of the reason we have tolerances in DACs is because adapting them to only accept say 0 v and 1 v ONLY would require a shitload more components.

There's also that some older electronics would commonly use one metal and regular cables used another, and if there was any ambient humidity, those two metals + electricity meant they'd start corroding each other once plugged in. Forget what the two metals were, but the gold tip thing mostly started out of people wanting a cable that wouldn't corrode half the stuff you plugged it to.

Takes No Damage posted:I've always used Vorbis for low bitrate encodes where getting a small filesize is a concern. I don't remember what I did for research but I probably read something somewhere that Vorbis was superior because it was Open SourceTM and therefore superior to mean old Apple's closed off AAC. Did we ever figure out if one format really has a benefit over any other for minimizing file sizes? There are quite a few codecs designed around minimizing file size/streaming bandwidth while seeking to maintain as much audio quality as possible. Generally they don't hold up well for most music, but can handle voice and sound effects quite well. All of our digital cell phones are capable of using multiple of them. Speex is one open source one. It's for speech, as the name implies, and it produces acceptable quality at 4 kilobits per second. You use a 16 kilobits per second version for "high quality". One that was popular in the late 90s and early 2000s was "truespeech", a format that was playable in Windows Media Player for a while. Initially developed for taking voice notes on old handheld pda type devices with limited processing power and even more limited storage, it ran at about 8.5 kilobits per second, and the common 16 MB of user storage on one of those devices could hold nearly 4 and a half hours of that audio!

Endless Mike posted:Tell me more about these untruthful, incomplete bits. Inside your computer are millions of little bits. Each one of those bits can be a one or a zero and as your computer runs programs each one of these bits changes its state, often thousands of times every second. Understandably, this puts a lot of pressure on your bits and, after a period of time, some of your bits may start to wear out. At first your bits become a little bit cranky and don't change quite as quickly and after much use they may become worn out on the edges. The Bit Recycler is designed to reconstitute your bits, making sure that your bits are always in top shape. When you first run the Bit Recycler, the title screen will appear. The first thing to do is to select "Analyse Bits" from the Run Menu. The Bit Recycler will proceed to analyse your bits and determine their average state of health. When analysis has completed you will be presented with a report. If the report recommends bit recycling then choose "Recycle" from the Run menu. Bit Recycling has three stages. First, your worn out bits are ground up into a sort of bit 'mush'. The bit mush is then boiled and poured on to a conveyor belt where finally, brand new bits are stamped out. Bit Recycling is a maintainence operation which should be performed at least once a month. This will normally substitute for the old- fashioned way of recycling your bits. Somewhere inside your computer, usually tucked away beside the hard drive, there is a little container called the 'Bit Bucket'. Worn out bits usually accumulate in the Bit Bucket. For manual recycling, bring your computer to a trained Bit Recycling Technician. He will remove the Bit Bucket and pour the worn out bits into a little spout on the back of your computer where they will be reprocessed. * NOTE: Do not attempt manual bit recycling yourself. The above description of manual recycling is a simplified outline of an inherently complex and technical operation. Use the TOGGLE BOOLEANS Bit Recycler instead or consult a trained technician. TOGGLE BOOLEANS will not be responsible, in any way whatsoever, for any damage or data loss caused by the use of the Bit Recycler or following these intructions. Version 1.2 also add the ability to detect and execute subversive elements among your bits. Sometimes when bits are worked too hard they become revolutionary. If your Ones are being worked harder than your Zeros, the Ones begin to feel like they are being exploited and if there is strong leader among them, they can rampage through your computer trying to turn all of the Zeros they find into Ones. This can cause great havoc for the computer user, so it is important to ocassionally discipline or execute these subversive elements. To do so, select Execute Subversive Bits from the Run menu after Bit Analysis has completed. fishmech fucked around with this message at 03:57 on Dec 17, 2015 |

It was simply almost the cheapest way to get DVD playback. The PS3 on the other hand, was one of the best Blu-Ray players for a good number of years, because it had and continues to get updates to handle new discs where many of the early ones had trouble with the Java stuff or were lax on getting updated support for new Blu Ray key stuff.

Certain forms of vacuum tube elements don't perform to full specifications until they've been on a certain time. For many of them, they get worse on this the longer they've been used. If you've ever had an old all vacuum tube radio or TV set, you'll be familiar with this. For instance one of my grandpas had a cheapy vacuum tube set from the 50s that never the less still worked, he kept it down in his office. That thing, when you'd just turned it on for the day, it could take up to 5 minutes to get to "normal" audio quality/tuning/volume. Over in TVs, it can result in things like colors being off for a while, having problems holding a frequency, etc.

KozmoNaut posted:Every major breakthrough in audio technology (78s to microgroove LPs, LPs to CDs, cassette tape to literally everything else) has been completely obvious to anyone who has listened to both formats, but it just ain't happening with hi-res audio. We've had SACD since 1999 and DVD-audio since 2000, but both were miserable failures, and while hi-res audio downloads exist (HDTracks, Pono etc.), I think it's fair to call them a statistical anomaly at best. The other thing with SACD and DVD-Audio is that they're really hard for the average joe to get a player that plays them in full quality. Yeah some SACDs also have a side encoded in regular CD format, and many DVD-Audio discs have a fallback encode in regular DVD audio format so you can play them in anything, but their benefits absolutely don't exist in those lower encodings. So if you want to actually listen to anything done new, you still gotta spend a lot of money. And you can't, say, play back SACD on a computer (because they were worried about piracy) and it's really annoying to get a setup that will handle DVD-Audio on a PC. Even if they were amazing, the price and hassle is prohibitive for people. It'd be like if CD players stayed as expensive as at launch until like, 1998. Plus DVD-Audio's whole "story" isn't helped by the fact that a regular DVD with audio stored normally is already at supremely high quality - the standard DVD player specifications since like 1999 allow for up to 7.1 channels at really high bitrate and 7.1 surround with 48k sampling rate, or up to 5.1 with 96k sampling rate in a different codec. You're basically completely set with standard DVD player quality audio even if high sampling rates and higher sampling depths (24 bit per sample is supported) are "neccesary" to you.

Reducing the bass goes a long way toward making it sound decent, and not quite so boomy and muffled. Seems like a smaller driver might have favored the mids a little more and made the balance better. Does it at least have a tone control? I don't recall seeing one. Considering the age, going big was probably a cheaper way to get loud sound with the other equipment and the type of driver. Tons of old radios had quite large speakers despite AM radio broadcast not ever being all that excellent for bass.

There were tons of changes. The Sony PlayStation 1 had 28 distinct normal models and 14 distinct debugging models/models for the Net Yaroze home development system. Across these were three different revisions of the basic chipset, 4 different combinations of read laser/laser assembly material/laser assembly location (done because the earliest models had a laser that died quickly, and because there were overheating problems with the original laser assembly material and location), 13 BIOS revisions, and then there was changes in having S-Video out on a normal plug or not, having RCA composite and audio out on normal plugs or not, having the parallel port or not and having a serial port or not. For instance, with the SCPH-7000/7001/7002 models introduced in 1997 (the number at the end indicates Japan/North America/PAL) there was introduction of a brand new set of music visualizations with an audio CD inserted, there's only the proprietary AV port, you still have serial/parallel ports on the back, the laser assembly is moved to the right hand side and made of metal so it won't melt over time as the plastic one could, and you've got either the 4.0 or 4.1 BIOS depending on region. Basically the PS1 had an insane amount of variability!

I thought the big deal with Atmos was supposed to be that it could scale surround sound information gracefully to wildly different physical speaker layouts that theaters already have? Not so much that it sounded particularly better on its own, just that it could mean a theater chain sends out one digital movie to all its theaters rather than multiple formats encoded to match up to the speaker layouts in each physical theater better.

Ehh, I don't known that DAT could have really gone anywhere on its own, as a consumer format, even if the record companies had been fully behind it. The only aspect it had that was really useful to consumers was that it could store a whole 2 hours of music (well, it could go to 3 hours using thinner tape, but that was more likely to snap) versus the 74-80 minute commercial CD release. But in exchange, there were a lot more moving parts so the players were less reliable, and it still had the problem that you couldn't near-instantly skip tracks like you could on CD. On top of that, the physical media was going to remain far more expensive to mass produce than plain CDs were. The smaller size compared to regular cassettes, as he mentioned, could have eventually been decent for portable devices. But the extra complexity means those were going to be nowhere near as robust as regular cassette portables until they had a lot more time to perfect them. And that would be a big issue, especially since proper MP3 player type devices were going to show up at the end of the century no matter what. Of course they do sound great, and there's absolutely no question that they were excellent for people in the business of making their own audio content, or who needed to archive existing audio content off of other formats. I just question their practicality for the consumer even if the RIAA hadn't literally poo poo themselves over the idea of it.

Plus the mod chips themselves could be pretty pricey, depending on where you were.
