talk about delusonal,
not too sure what you actually read inside that bubble of yours...
i never made any claims as to the fiscal propietary-ness of obama. unless of course you are reading the version of this site scraped by fox news and re-presented in o'reileyVision.

whaaaaaa
a republican talking about the mis-appropriation of public money???
so i guess the answer to the question "Who were the republicans trying to fool by not having Bush, or any of his cabinet attend their last convention?" would be _you_ then. And a bloody good job they have done.
Seeing as the tide is out right now, i have a once-in-a-lifetime deal on some prime development land that only a smart operator like you, or that very nice Mr trump would be interested in......
'cept the problem is not with sugar, its with Aspartame. about which there is considerable debate.
indeed depression is pretty low on the list of claimed issues:
multiple sclerosis, systemic lupus, methanol toxicity, blindness, spasms, shooting pains, seizures, headaches, depression, anxiety, memory loss, birth defects and death.
persny i'd rather suck shit through an oily rag than drink any of this crap, so i aint that worried.
There is no such thing as a digital signal,
conversely find me an mpeg decoder that can decode a stream that isn't analougue (i.e. made of volts and amps, suffering from ohms, farrads and henries)
it may be encoded in a way that _can be seen_ as digital, but the nature of the signal is analogue.
Ill see your Jethro Tull and raise you a Steely Dan.
At least with a bogus tab you can kinda use it to work out whats wrong and thereby get the correct chord/voicing in the end.
Much more irritating - try finding a tab for chuck e's in love - loads of hits, all for just the intro (the piss easy bit)
Terrorism: Setting a bomb on the public street?
I think you'll find that rather depends on the street, something with a W1 post code, most certainly, something with a Basra postcode, not so much.
The word is _entirely_ subjective and malleable, that's why they love to use it so often.

there fixed it for you.

neoliberals??
what about the neocons
think of the great merkin traditions regarding the second amendment and prayer in schools (I.E they know they are absolutely, undeniably wrongheaded but stick to their guns - like John fucking Wayne or something, and therefore make a virtue of ignorance and stupidity {take a bow mrs Palin}) this means merkin consumption will continue apace, and whatever the civilized world does wont make any difference. this wont make america irrelevant...
it makes them the enemy.
the hum is NOT 'recorded' with the mic. it's NOT audio, its (as you point out) EM. its superimposed on the electronic signal derived from the audio signal from your mic.
the camera is - though sucking the data back out of a photo after jpeg compression would be CONSIDERABLY more complex.
AH! iTunes
nuff said, im an android man myself, plenty to choose from in our store, but then they let any old maniac write malware for droids apparently(who'd have thunk it)
you say phase lag, i say frequency change :-)
y' cant have one without the other. in order to go out of phase, something needs to slow down/speed up
all the power stations have to be in phase (theres kit to auto lock them out if they arent - can you imagine how loud the bang would bee if you closed 500MW onto a grid that was 180degrees out!)
i hope your sampler is running a little faster than 60Hz btw!
if the recording medium was electronic, then a clockwork recorder would still have the hum.
the second para conflates science with statistics. saying one is 'sure' of something without sufficient evidence is always going to end in tears. - in this case, im sure the frequency record has already been sufficiently analysed to be able to say that 'we need a recording sample X seconds long to be able to have a significant probability of a match' as with DNA.
it's not audible recording, the hum comes from the electromagnetic field produced by all those wires, the audible part comes from the nature of the recording machine - the field creates small eddy currents in the components of the recording device which are, to the device, indistinguishable from the signals coming from the microphone.
you clearly have a smart phone - get an app that reads field strength - search your app store for 'EMF', then go play golf and prepare yourself for a shock (figuratively, that is)
the fft is how it works.
hence absolute time domain fidelity between recording and playback devices is irrelevant.
it started a X hz after 20 seconds went up to x+0.01 then after a further 30 seconds went to x-0.02
calculate the difference between the recording devices value for x, and the playbacks version of x, multiply out the time changes, et voila.
i call your bollocks and raise you more bollocks!
you do not see pitch shift on recordings carried out this way.
you just don't
ever
maybe in the bad old days on tape, but even then only when the tape had been used a million times before and the recorder was on it's last legs.
i play and record on a vast array of kit of varying qualities and tuning just isn't an issue (i have pretty good pitch, but my SA is better)
wiki SMPSU (Switched Mode Power Supply)
All that most kit sees that frequency dependent these days is 4 diodes (or a bridge), 2 big assed electrolytic capacitors, a fuse, a switch, and a beefy as you like chopper transistor.
with the loop impedance and the size of the (low esr) electrolytics, 50hz looks as close to 60hz as makes no difference.
most of the rest of it is DC, and the bits that aren't sort their own frequencies out (much much higher than transmission frequencies)
mains out of phase??
you getting the power for your telly from a different grid (that is, as good as saying continent!) to the one supplying your computer - neat trick that.
(hint, no you aren't, you just misunderstand the premise - besides all the kit you mention would have SMPSU's and that a whole other can of worms)
I think you'd need a rather expensive recorder to pitch shift on the fly as opposed to a cheap one.
you think that slight variations in clock speed in a clock running at 100's or more probably 1000's of Mhz will have a lot of influence over a 50/60Hz hum??? (not my understanding of the behavior of crystals - a few cycles per billion if theres a massive temperature shift, but pretty stable otherwise)
DOH!
the hum is everywhere, any ferrous metal will pick it up.
quoting 2 numbers for a filter is almost meaningless
we are looking at signals way below the s/n threshold anyways
all the filter does is _reduce_ the signal level below a threshold
reduce != remove
depends on the filter!
a bog standard butterworth 3db/octave jobbie, or simml'a would see the mains hum down by 6 db, or 25% of what it was to start with.
zillionthth order chebyshev, prolly down by a lot more :-)
but the purpose of this type of analysis is not so much identifying hookie copies of commercial recordings, but establishing the veracity and continuity of covert recordings. the record can show that _this_ is when the recording was made, and _that_ is what the defendant said - un-edited. If the record is corrupted or contains any anomalies then it is just another piece of contaminated evidence and will be chucked out faster than OJ's sock.
out in the country?
really, if you are standing 'out in the country' and cant see a pylon or pole line, chances are you are standing on top of a cable!
I don't know for sure, but i would expect there are _very_ few places on earth entirely free of mains derived emf.
frequency is extremely stable
nope
as load varies (ppl using power) the the mech load on the generating sets changes, as more or less generating capacity is added/removed this also changes the loading, this causes stuff to spin up or down - F=ma and all that(we are talking very small amounts) - this is how demand is managed, control sees the frequency drop and brings more capacity online to meet it. the only other way is to.....
.....
well use a medium to tell you _exactly_what the load will be in 2 minutes time
anything that changes the relationship between the load and the generating capacity will change frequency - that's what makes a 'black start' so hard to accomplish*
*
black start - bringing everything back from a catastrophic failure of the grid - the large fluctuations in load as circuits are switched back in and generators brought online tends to cause other generation to drop outside of its frequency range and therefore automatically disconnect itself from the grid, this makes the original problem worse, knock out more generation and so on and so on till we are all in the dark again.
This is why it takes to long to recover from a cascade failure, and i don't think anyone with any knowledge of the history of T&D could claim that this is an unknown phenomenon in the US :-D in fact when i think cascade failure the first thing i think of is the US! they have had a couple of doozies over the years
As far as this technique is concerned AFAIK it's been around for donkeys years (well.. ish) and is well understood, and pretty much impossible to fake.
(clue - your master blackhat recording tech when adding in his 'fake' hum will end up with 3 hums!, the original, his fake, and the one laid down when he did the fakery. immediately exposing the recording as doctored, and therefore unreliable.
