Comment Re: how can you not play an audio file? (Score 2) 440

Can you give any examples of music that is permanently lost to an unpopular format or bad DRM? It may happen in the future that some music is abandoned due to software but music is already being lost due to lack of playback hardware. He can stomp his feet and say that tape is best but there will be a time when no one makes tape players any more, it is pretty unlikely that there will be a point in the future when we stop using computers to play back media.

How about the Doomsday Book? Not music, but an unholy hybrid of laserdisc media using a proprietary variant hooked up to a 512k BBC Micro.

To be sure, there are a lot of examples of things that would have been lost if they had been digital - most of the recovered Dr. Who episodes, that Woody Guthrie concert from 1949, the stereo masters for Jesus Christ Superstar, Court of the Crimson King and untold others.

A lot of people in this thread seem to have been pooh-poohing the idea of using tape as an archival format, saying that you should store everything digitally and constantly reconvert it to new formats - for some reason this isn't seen as a problem, even though all of the things I've listed above were found in a shoe box or in the back of a long-forgotten cupboard etc. 40 years after they were made (nearly 60 for the Guthrie wire recordings).

No, mag tape is not perfect, and yes, some of the more exotic formats are getting difficult to play back. But archival masters are in standard formats for that reason, and it's not outrageously hard to make a machine capable of playing them back - even the sticky shed issue is understood and fixable. Mag tape is not perfect, but it can be played back after being left forgotten in a vault for decades and that is something digital does not currently offer.

Bottom line? Make digital and analogue copies. That way, at least one of them should survive.

The hilarious thing about this is that I don't think anyone even makes analogue tape machines, right now. I checked Fostex, Studer, and Tascam. No tape machines being made.

Given this .. how easy will it be to play an analogue reel to reel tape in a few short years ?

I'd say it's more like decades. I believe Otari are still making the 5050. There are others who are reconditioning older machines (ATR Service for one) and the market for rubber rollers and drive belts has become something of a cottage industry. The big problem for manufacturing new decks is that ebay is flooded with the things and that makes it very, very difficult to compete with new equipment.

Comment Re:why not a record then? (Score 2) 440

Saying tape has a longer life is silly. I'd have no idea where to get an 8-track player today even though it's an analog format.

Same with a record player, but I could make one pretty easily. (there's a reason why we shot a record into space instead of a tape)

Really, though a documented and uncompressed digital file, properly kept track of, could last forever similar to a record even if we lost our codecs it would be easy to write a new one.

To turn your argument around, I've had CD-Rs go bad and those are a digital format... It is worth keeping in mind that archiving something onto tape is a known science, and that 8-track was a cheap, disposable format that no-one ever used for archiving.

There are standard archival formats for tape (1/4", usually 15ips, 2 track, no NR, either NAB or IEC curve depending if you're in the US or Europe). Back in the day this was pretty much the universal format - the album would be mixed to that, the duplication master would go to the pressing plant in that format, when they remaster something from the original master tapes today, the source media will be in that format also. To play it back, you need a machine that runs the tape in front of a pair of coils at a constant 38 cm/sec. Unless the tape is of a type that goes sticky, you should be able to recover the audio, regardless of age, and that is not something you could say the same of for a Protools project on a flash drive.

And the longevity of analog tape? It decays. We have a steady stream of older musicians who are desperate to use our ancient reel-to-reels for a chance to digitize their brittle, fragile old tape recordings.

No storage medium is permanent, but PCM audio has remained mostly unchanged since Max Mathews, Bell Labs, 1957.

Depends on the substrate and adhesive. I suspect there are Nazi-era tapes that are still playable (this was certainly the case as of 1991, see 'The Secret Life of the Video Recorder': http://www.youtube.com/watch?feature=player_detailpage&v=gOULWR4h4Io#t=1017 ...17 minutes in)

There were a lot of problems with tapestock from 1975-1994 which used a synthetic substitute for whale oil. Japanese tapes that carried on using whale oil (Maxell) and formulations prior to this are rock-solid, and Ampex/Quantegy tape from 1995 and later have proven stable to date. When it comes to being able to stick it on a shelf and play it back 20 years later (or in the case of 'Jesus Christ Superstar', 42 years later), digital formats simply aren't in the same ballpark - and I suspect a lot of this is because the density has increased so much.

First program I ever wrote was on the used Casio Graph 25 I got, and that one wasn't even a powerful or well done language.
By the end of high school I had a used Graph 65 where I wrote minesweeper, chess clock, mandelbrot set plot, and one of those bomber games which sucked since the display was too slow for it (It had a colour one) and a good couple of calculation programs - and it brought me to trying to program on a computer (C and Fortran 77). For kids who have some interest in messing with this sort of a thing, programmable calculators are a great starter that you can poke around in and do fun, rewarding things, unlike a computer where you have to learn a fuckton just to do basic things.

The only proof of this happening is your assertion. As far as I'm concerned, it's scumbags being executed - say the directors responsible for the melamin saturated human and pet foods. And thousands others. I fail to see why such scum should not be used.
Besides, if the rich want, they can get organs off the black markets, for example, Serbian kidneys by which the albanian scum financed their terrorist gatherings that , with western support, caused Kosovo to split off.

The other problem with a Midi file (and regular sheet music) is that, while it provides instructions for playing a piece of music, it doesn't give you a means of duplicating a performance exactly. For instance, if someone with thousands of dollars worth of proprietary audio software, sound samples, and production equipment produces a midi file of an orchestra, it's going to sounds pretty damn good. Give the sheet music to a conductor of an orchestra, and it's gong to sound amazing. Give the midi file to a random person with a computer and it's going to sound like it's being played on a gameboy.

Occasionally I've pondered releasing the MIDI (or Rosegarden) files for some of my songs, and that's one of the reasons I've balked at it - you need to have a fairly good grasp of MIDI to be able to play it back at all. Most MIDI files you find on the 'net are GM standard, with 128 preset instruments which will play back more-or-less the same on any GM-compatible device.

That works for the music in DOOM, but it all goes out the window once you start writing MIDI files for a Korg Triton EX on one interface, Hammond Organ clone on another, a digital mellotron clone daisy-chained to that, and on the other interface a bunch of analogue polysynths and a monosynth with custom patches, filter sweeps on the controller usually used for changing the MIDI bank, and a pitch bend wheel that spans two octaves. With a bit of effort you could map it to GM (assuming you're not doing minimoog solos which depend on monophonic note priorities), but you'd end up with a pale shadow of the song compared to the recorded version.

By every meaningful measure these die shrinks improve the technology.

How about data retention? That is also a function of the cell size, since the more electrons you have in the charge trap, the greater the difference between 1 and 0. Intel's drives, for example, are only guaranteed to hold their contents for three months without power. And when they are powered, they keep the data alive by periodically rewriting it, which I strongly suspect amounts to a P/E cycle. (Not sure about flash, but a lot of memory devices use an 'erase' to set the bits high, and then short out the ones they want to be zero, so a lot more actions are liable to count as an performing an 'erase' than deleting a file.)

Ok, you're old fashioned.

This was a thing, yes, but only for that brief period when you actually got your slashdot id. Since then? Not so much ...

Technically it becomes less and less reliable each time they do a die shrink on the flash. Adding a whole extra bit level makes things worse still. In the early 2000s you were looking at 100'000 P/E cycles, maybe a million for the really good stuff. Good TLC memory seems to be rated around 3000, with a figure of 1000 being widely quoted, and in some cases, less.

Realistically, they've designed the drive to fight tooth and nail to avoid doing rewrites, and in actual fact it looks like they've put a layer of fast SLC cache in front (i.e. the million-cycle stuff). What could be more interesting is the retention period - if the thing is left powered off for three months it could well be left unreadable.

Okay, he is, now, best known for the Malcolm Tucker role but I remember him better in other roles; the Angel Islington in a BBC adaption of Neil Gaiman's Neverwhere (although that show was really stolen by Paterson Joseph's Marquis De Carabas) and as Uncle Rory in the TV adaption of Iain Bank's Crow Road.

And it's kind of nice that the Doctor is portrayed by an actor older than me again. That hasn't happened for a while.

So, does that make Rory his only non-psychopathic role so far?

Agreed. And ... it's nothing to do with actual schedule, morning or evening. The point is that I can easier do more stuff during the late (near going to bed) part of my daily cycle than the early (after waking) one - for half an hour after waking, I probably wouldn't pass Turing test x3.
Which is the actual reason for being a night owl (schedule is constrained by waking time to go to lectures/work)
