The Kickstarter clearly shows the specs as being 192KHz / 24 bits, they even give a lovely comparison of recording qualities:
Which is a bit silly for listening purposes. For one, the human ear doesn't go that far up. Then, you will surely get problems with winding a suitable speaker to reproduce it (even an earphone-speaker). The amplifier might want to have a word here as well. Oh, and please show me the equipment used in recording that can actually make use of that frequency range as well.
I wish people would quit quoting this guy. If he actually cared about vorbis quality at the high end, he would have incorporated the aotuv patch a long time ago.
Actually, if you train yourself to identify MP3 compression artifacts (which is a terrible thing to do and will haunt you for years afterwards), this is surprisingly easy. MP3 is simply not transparent at any bitrate. AAC is a different story and did become transparent for me somewhere between 192-256 (IIRC, this was quite a while ago).

you miss the point. its not about reproducing audio up that far; the main reason why there are high sample rates are:
1) you want to shift the filtering up high enough so that its outside the audio band. nothing to do with hearing high freqs.
2) on initial capture, you want the highest res samples you can get. when making finals for USERS, though, its almost always downres'd to 96k or even 88k. this is generally recognized as the right balance of samplerate for playback vs filesize.
similar to photography: I will capture images at raw but I'll never 'release' raws to end users; they get 8bit jpgs.
88k and 96k do make sense for the listener.
it makes life easier on the dac and whole digital audio system.
its not about the listener; its about implementation. you should try to get that point.
It all depends how you look at it. a glance on a tv that shows your pics as a slideshow (as an example) vs 100% zoom on a calibrated monitor where you look closely at every single detail and colour. Same goes for music. most listeners listen audio on relatively low quality speakers/headphones where 128 mp3 sounds pretty good. Hoverer if you let someone to listen the same mp3 on a high end setup - they will notice that it doesn't sound as good as flac.
But only if they expect to. If they aren't aware that there should be a difference, they won't hear one. And if you tell them the mp3 should sound better than the flac, they'll hear that too.
Placebos are great that way.
having more (overkill) means that you are certainly more accurate down where the human cutoff is, at that 20k mark that is so frequently referred to. 2x of 44k is 88k and that's the reason for 88 (88.2, really). and 2x of 48k is 96k and that's why that is used. beyond 96k, it does not make sense for the end user and it just wastes file size and adds network and codec load, which I find wasteful
That's where you are wrong somehow. Look up intermodulation on amplifiers. Pretty much every decent amp low-pass filters the signal.
You are just as wrong as the people who think that expensive power cords improve sound quality. 128 kbit/s MP3s are trivial to ABX on halfway decent equipment.
That's where you are wrong somehow. Look up intermodulation on amplifiers. Pretty much every decent amp low-pass filters the signal.some of the better designs have bw up to 100k. it has a lot to do with keeping phase; again, not max human hearing range, but phase.
define low-pass.
... headphone amp that I run goes well to 100k ...
its fine if you disagree, but don't be so sure of yourself, that's all I'm saying. a lot of serious designers create high bw amps and preamps.
ok, chris. you know everything.
I'm done with you. you don't have an open mind and I won't be able to reach you.
both exceed 100k by a large margin. yes, that is 'higher than human hearing'. that's not the point, as I've been saying.
Edit: This reminds me of the gaming folks who spend boatloads of money on a graphics card, only to proclaim "hey, in game X i get 200 fps now!". Which is pretty useless when the screen they look at has a refresh rate of 60 Hz...
... that the phase doesn't shift at even 20k, when you have a much higher bw allowed by the amp.
there are also instruments that actually do have useful info into the 30k range.
and pro audio systems can record that high (special ones can). digital audio at redbook (44.1) cuts off hard at about 20k but with new high res 'file based' audio, you can get downloadable 88k and 96k files and they really could contain some of those upper harmonics.
seriously, go ask papa (nelson, lol) why he designs stuff with such high bandwidth. if you are serious about your views and you want to know first-hand, GO TO DIYAUDIO and ask! stop badgering me about this.

60 Hz ~ 16milliseconds. Many monitors give below 5ms update time.
The high frame rate gives smaller latency, that is were you get some benefit. Especially if you are having network or other issues.
I wish I had 200fps.
I would rek.
In fact, you see what people are going to do before they even know that they will do it! Like a magic time machine!
chris, please stop before you look even more foolish.
if you have never heard of nelson pass, PLEASE google it a bit first.
you are really acting foolish, here. that high
I'm out of this thread. if that displeases you, too bad.
