3 segments video audio. Which audio segment sounds better ?

Well the first two are fairly noisy and the third has some music or something going on in the BG so hard to tell how noisy.

The noise could have been laptop? in the first. Sounded more mechanical than electronic but? The noise in the first two could probably be removed in post not so much with the third.

Voice wise the first two seemed similar and the last seemed a bit brighter.

But with you just talking it's not a very good test unless you are planning to film yourself just talking. Most actors for instance would project more, interviewed folks tent to be more lively. In any case you need to pay more attention to the stuff you don't want and make sure you are not recording it. One of the hardest lessons with recording is that you really NEED to listen for what you don't want. You brain will very effectively filter out stuff it's not interested in and it is really easy to miss the fact that the recording is ruined by some noise you didn't notice while recording.

Now I know your just thinking of the vocal quality, BUT if I have to do a bunch of noise reduction and slicing and dicing to get junk out that got recorded by accident it will have a BIG impact on the vocal quality that is left so it is related.

Related to that. The noise in the first two is also fairly steady so editing wont produce a bunch of distracting jumps in continuity in the BG noise. The third one though because it has some musical aspect will make cutting very difficult with out a bunch of cleanup. So I would rate the third clip lowest for usability.
 
I concur w/ Gary, all three are acceptable. #1 as a little more HF detail, #3 seems slightly louder, which can skew one's perception.
A little compression may help.. The levels are kind of low as well (at least on the YT clip).
FWIW, I wouldn't use ATSC ro EBU loudness standards for on-line DVD or BD content.
 
Hi,
1st clip : Noiz2 said it sounds more mechanical than electronic ? Is it a good thing?
Rick R said it has a little more HF details. what does it means ?

Rick R (2nd question): You said you wouldn't use ATSC or EBU loudness standards for online dvd or BD content.
I try to have a level of audio for voice around -4.5dB

2nd question :
I thought of buying a juicedlink to add 30dB clean gain on my camcorder.
Will i have better signal to noise ratio and more loudness than if i use only a pcm-m10 connected to my camcorder ?

Thanks in advance,

What I mean is it could be noise from the laptop, fan etc. as opposed to the white noise hiss of a noisy mic chain.

"Clean gain" is... kind of advertising talk. 30db is a LOT of gain and it's not going to clean anything up. Hopefully it won't add a lot of noise on it's own.
BUT your going into a camcorder so the "somewhat mechanical" noise may actually be the less than great audio on the camcorder picking up camera related RF and adding that into the noise.

As the others have said they are all "acceptable", though exactly what that means depends a LOT on what you plan to do with it.

If it Run and Gun Doc. interviews yes it's better than many things I have gotten. If it's for a narrative that doesn't have a budget for sound post then they start to get more problematic, especially the third one. The vocals on all are all usable but the background noises could end up being a real problem.

Personally I doubt that a JuceLink would help much. Unless you have AGC that you can't turn off, then one of the JuceLink units designed to defeat that could help.
