It seemed fine to me, comparing to some of your other tracks.

I find the idea of calibration interesting. If it's just to help set the le=
vels, in my case I don't see the point because I've only got two mics, so I=
 can just remember what I used last time. If it's to be able to estimate SP=
Ls, as someone mentioned in another thread today, when would that be useful=
? And doesn't the same thing apply about remembering the levels?

Or are there other factors that make sound levels vary that I haven't yet e=
nountered in my short recording career? Do different cables affect sound le=
vels (I've only got one set I use)?

I've given up trying to listen to nature recordings other than with headpho=
nes. It's just too noisy around here.

I hope I'm not side tracking the original purpose of your posting here.

Hi Peter,

Yes, they could always turn it down - or turn it up.
Did it seem to loud to you?

"Natural" in this case is based on my embarrassingly imprecise calibration =
method of speaking in a natural voice one meter in front of the mics, and n=
oting the gain setting on the recorder where that voice comes to about -30d=
B on the recording levels. I arbitrarily chose -30dB because that is what M=
artyn says he uses with his calibration method, plus it seems to allow plen=
ty of headroom while still enough saturation for accuracy of most quiet nat=
ural ambience.

I amplify or attenuate for consistency in comfortable playback levels betwe=
en a variety of my material.

For this particular location the natural ambience was probably at least 10 =
dB lower than the ambient noise level of my listening environment at home. =
For that reason trying to listen to the recording at a "natural" level woul=
d be completely futile.
