The bit depth (read: word length) of an audio file defines its dynamic range. CDs are 16 bit, which is 96dB of dynamic range, minus a little dithering at the bottom end. 24 bit would get you 144dB, which is unusable in any audio system. Even 96dB of dynamic range is barely achievable with extremely low noise electronics in very well sound proofed rooms. This is almost certainly a moot point given that most modern recordings have about an 8dB crest (peak to average) factor.
Increasing the sample rate a little is probably a good step, but again modern AD/DA converters deal with this quite well. Properly reconstructed (read: oversampled) there should be no difference to our ears (which can barely hear past 18kHz) from an increased sample rate, and there is a much greater burden on the processing hardware. File size will also go up.
The real issue is that neither of these specifications defines audio quality. iTunes Plus did increase audio quality by doubling the bitrate of the AAC codec. I cannot hear the difference between CD and 256AAC. If I can't hear it it's unlikely than almost anyone can.
Hell, I'm surprised to find my college at #1. I guess, however, when I think of the prevalence of bits around here, it makes sense. I probably would have picked Dartmouth, but hey, I'm not complaining. Shows what I know.
But now what happens if I use it to watch porn while driving? Obviously, NY needs to institute a hands-free driving law for more than mobile phones. The death toll could reach thousands!
Well, as long as we're at it, why not use the device to power itself thereby providing a never-ending power source that requires a simple flick of the wrist to start and will generate as much power as you need while solving global warming and reducing CFCs in the upper atmosphere. While it would be really cool if this worked, I don't see how it can be possible. There's got to be some trick somewhere, gullible businesses aside. I won't believe it until I have one of my own that I use to drive my car off of no battery at all.
You may want to ask this question on the theatre-sound mailing list. This list has a broad and diverse membership, ranging from high school theater buffs (like you) to freelance reinforcement companies (like me) to the guys who actually build the hardware (like two of the techs at Cadac).

Yeah... after I enabled filevault (back before 7B85 was even officially released!) and had to sell my soul to get it disabled and my data back out of a shambles (I have backups, but that thing corrupted everything), I'm also going to wait until enabling filevault.
The encryption isn't as cool as it seems. Running 7B85 it insists on creating a duplicate home directory in an encrypted disk image, eating up twice as much space.
I'm a huge fan of Sensa pens. They're well balanced, have a nice grip, and use space pen ink, which I'm also a big fan of. They're not cheap... start around $60, so not something you want to get if you're apt-get to lose things. (Get it? Apt-get! Haha!). However, they're the only pens I can write with and not wear out my wrist.
I haven't heard anything about Dartmouth's network failing... I've been leeching WiFi from them for years. It's pretty good, and has been getting better. Now that my grandmother has DSL, however, I leech her service and fix her computers. In return she feeds me cookies:)
I would imagine that 80-90% of Hanover's population would be interested in this. Most people are out too far for any other kind of internet access anyway, and will want something better than dialup. The remainder want better TV programming for cheaper or faster internet for cheaper.
I don't know how possible that will be. At the moment, it looks like this is going to be less like an ISP as most people know it (everyone has an account, specific to their line/location) and more like the network in most of our homes. You plug in (or connect wirelessly) and there's your bandwidth. Want to talk to Joe across town? Fully switched. Send those files. Of course, all speculation.
I have no clue about the organization that will be established to manage this. We have a strong local government, vocal citizens, and a plethora of technical end-users. I imagine that know-how will not be a problem, even if a bunch of people _do_ leave town. As for rates, no idea. I disagree that flat rate pricing won't work out. With the kind of people I know around this area, they'll get a ridiculously fat pipe that no 1337 scripter can swamp. If the network is designed properly, it will be very difficult to abuse.
I suspect there's more coverage in town than there is on college land. I routinely sit in Subway, eating my sandwich and surfing. I hope that the town doesn't tie in e-mail with blitzmail... anyone who knows anything about that system's underside knows it's disgusting. Here's a question: I wonder if sone kind of slash-like town information site is going to spring up from this? Online voting? School cancellations and road conditions delivered to your.name@hanovernh.org?
That's what I'm worried about. I've just put a significant (OK, not that significant, but still) amount of effort into ensuring that all communication between me and my co-conspirators on a potentially money-making net venture is secure. Should I now worry that all of my e-mail since this summer can be read?

Yeah, right, put a link to a 4.9MB file on the front page of slashdot. Gooood idea.
Like shooting fish in a barrel.

"The low-voltage chips will use smaller batteries and produce less heat."
;)
So these processors have built in batteries, eh?

You're going to need a good sound tech, too. If you'd like to rent my golden ears, I'm available.
I think, maybe, it was a joke.
He's got a paypal account now... send money to his e-mail address if you're interested.

Ahhh. Thank you very much. I will be correct in the future.
Over here, everything is property taxes.

Yeah, that was one of the questions I asked on my survey.
Holy shit! The duke nukem source is available? Rock on! Where?

Great, and this after I've been bragging about my 'not-breakable for a billion years' 2048-bit key.

Hey... get on I-91 instead and cruise through New Hampshire. Stop by my house and you can use my 56K dialup-supplied acccess point...
