As someone who listens to a lot of music and is interested in high quality music, I like the move by apple to remove the headphone jack, and thus also the DAC inside the iphone. This will of course provide more space for other components. Some high end audio companies have already released external lightning connector DACs that are, ideally, better than whichever one was in the old iphone.

I really don't know how they're going to spin this one as anything but a blatant cash grab, the idea that the 3.5mm connection is obsolete is underpants on the head crazy.

They've understood their demographic very well and could get away with anything if they market it right. Watch the new iPhone break sales records.

They've already said they won't be releasing sales figures for opening weekend because "initial sales will be governed by supply, not demand" (read: we've artificially limited available units to try and increase an appearance of consumer demand by selling out) and their 4th quarter estimates are down $4-6 billion. The iPhone is still a juggernaut, but it is slowing. It's an incremental change in all areas except the ludicrous decision to drop the headphone jack.

That's actually a big problem for a company that, under Jobs, made huge leaps and, since his death, really hasn't. People compare the dropping of the headphone jack to leaving the floppy drive out of the iMac, but the iMac was a radical departure from the design language that existed across the computing world at the time. It was cool-as-gently caress and dropping the floppy was part of what made that possible. The only thing made possible by dropping the headphone jack is an uptick in wireless headphone sales (including Beats, owned by Apple). And yes, I realize they've made claims about how it gave them room for an hour or two more battery life or more haptic feedback on the loving home button, but ffs, they could have made it slightly thicker (i.e. as thick as the stupid camera bulge so the drat things sit flat on a table again) and doubled the battery life.

That's a silly comparison to begin with. Floppies got overtaken by storage media that offered higher capacity and more convenience, headphones are essentially unchanging.

Nothing you're going to plug into the Lightning port is going to provide audibly better sound quality than the DAC in an iPhone with a 3.5mm jack. It's way beyond human hearing already.

Or get in contact with the factory and have the Chinese child labour do that for you, too.

Here's the video of me spelling my first name with an Enigma.

https://www.youtube.com/watch?v=5SBNc-lpJXU

You can see how it works pretty clearly. Every time you press a key, a lamp lights up showing which letter to write down instead. The position of the rotors determines exactly which lamp lights up when each key is pressed. Pressing a key spins the rightmost rotor one position. Every certain number of rightmost rotor spins, the middle one spins. Every certain number of middle rotor spins, the leftmost one spins. Think hours, minutes, and seconds on a clock.

The original Enigmas could be pretty easily broken by hand once cryptographers figured out how they worked, as well as some sloppy behavior and less secure procedures used by the operators; one example was that operators would decide on the encryption key for each message, but there was a universal "ground setting" used to encrypt the key. The operator would put the ground setting in plain text at the top of the message, then set the machine to that setting and type the actual encryption key twice (if the key came out the same both times when decrypted, the receiving operator knew nothing got corrupted). The receiver would set their machine to the ground setting, type the first 6 encrypted letters to see the actual encryption key, and then set the machine to that key and decrypt the rest.

The problem is that by typing the letters twice, cryptographers were able to figure out that the 1st and 4th letters and so on were the same. By taking advantage of other known properties about how the machines worked (like no letter could ever be encrypted to itself, so an A in the encrypted document could never be an A in the plain text), they were able to work out the relationships between encrypted letters through hand charts just by getting a bunch of intercepted messages from a single day with the same ground setting.

Eventually this stopped working, as the Germans worked to eliminate flaws that would allow the messages to be decrypted by hand. This ended up driving the development of mechanical computers like the Bombes that would just try a ton of different machine setups at once, running through every possibility to figure out what settings to use to decrypt the message.

Speaking of "No letter can be encrypted to itself", here's one amazing incident from a 19-year-old girl who worked on decrypting Enigma messages:

quote:

The one snag with Enigma of course is the fact that if you press A, you can get every other letter but A. I picked up this message and—one was so used to looking at things and making instant decisions—I thought: 'Something's gone. What has this chap done? There is not a single L in this message.'

My chap had been told to send out a dummy message and he had just had a fag [cigarette] and pressed the last key on the keyboard, the L. So that was the only letter that didn't come out. We had got the biggest crib we ever had, the encypherment was LLLL, right through the message and that gave us the new wiring for the wheel [rotor]. That's the sort of thing we were trained to do. Instinctively look for something that had gone wrong or someone who had done something silly and torn up the rule book.

These dorks make it hard to tell the difference between legit audio concerns and magic. I can't speak for the Iphone, never had one, but a lot of consumer grade products, like on-board audio analog outputs on computers, don't sound all that great with nicer audio gear.

Now with less breakage.

The otherwise nice dell workstation I use at work is so electrically noisy inside that scrolling a browser window adds a distinct noise to the audio output; the cheap USB DAC/amp I bought was worth it just to not have to listen to that. That it also sounds better with my chunky headphones is more of a bonus. :)

There still needs to be a DAC in the phone, it has speakers after all.

Anyway I'd be surprised if the Lightening to headphone adapter (and the bundled headphones) aren't just being passed analogue audio out of the phone anyway.

Speaking of digital output with smart dongles (and content relevant to this thread), the Gamecube had a digital video out port. A chip in connector of the official component video cables converted that to the necessary analogue signals.



It was really ahead of its time. It’s a shame they never released an HDMI cable, but IIRC fans have now made their own using FPGAs.
