From the other thread...


So, I looked at these videos from an audio-guys standpoint, and most of them seem pretty fishy.
I downloaded the videos, extracted the sound and analysed it using super secret pro audio toolz (Audacity):

Manitoba: This one is pretty ridiculous. The sounds don't even sound like they where recorded with the rest of the audio. They even have a bit of digital delay added, which makes this even more obvious. Listen to the last part, after 41 seconds.
The sounds simply don't fit in. A cityscape like this would have very spread out/distant reflections. So, lots and lots of subtle reverb. Listen to the hammer tapping.
Also, the sounds are too clean. You could never get a sound this clean with a camera mic. Especially on the low end. It's just too good.
Ohh, and if you speed them up they sound exactly like when you scrape metal stuff with a violin bow. Add some digital reverb and delay, and you got it.

Dawson Creek:Speed it up, and its just some animal noises (sounds like a fucking safari). Boring. Also, a slowed down crash cymbal at 42 seconds. WTF? This was clearly added in post (well no shit), since it's frequencies reach up beyond 10khz, and the camera recording already stops at 5.5 khz. And again, knowing how bad camera mics are at picking up low frequencies, these sounds would have to very loud to appear this clear.

Alberta: The supposed volume (it would have to be very loud to be able to be heard in an entire forest) simply does not fit with the reverb and frequency range of the sound. It sounds like it was played from small shitty speakers (mobile phone) next to the camera. Here the total lack of low end is suspicious. The sound bottoms out at around 500hz, and even a shitty camera can do better than that.
If you speed it up, it sounds like the same metal scraping sounds from the first video.

Kiev: Same thing as with the first video. Almost exactly the same sounds/method.
Again, frequency response of camera does not fit with the sounds. Notice how the "tinnyness" of the camera mic is completely absent from the sounds? It just sounds too good. The Alberta guys at least made it sound shitty. Come on guys... You can do better than that.
Also, nobody else notices the sounds? They just keep an walking while it sounds like Godzilla is raping their city? Come on.

Denmark:No idea, could be anything. Sounds good and really fits into the video. Then again, if nobody hat told me to notice the "strange sound", I probably would not have even thought about it.

Montreal: What the fuck people, this is exactly the same sound that has been overlayed onto the first video. Come on. At least put some more effort into it. The delay/echo at the end is even more obvious in this one.

Virginia: No idea, but does definitely not sound like it's coming from the ground. And a high pitched, hissy, sound definitely does not feel "like the ground was shaking". When you speed it up, it sounds a bit like air escaping from something, or blowing over something.
Also, who would record a video like that? This is stupid.

Colorado: Just some sound effect overlayed onto the video. The stereo position does not even change when he turns around. It's always exactly the same sound. Always comes from the right, even when he turns around. Bad. They could have at least added some panning to the thing.

Costa Rica: No idea. The first and second part sound pretty good. The last part seems a bit strange, but the loud click at 1:35 correctly applied dynamic range compression to both the background noise and the strange sounds. This seems like something you would easily miss when adding sounds in post. Then again, they could have just recorded it from some speakers.
