Another small diaphragm mic test
 

Same Panasonic electret capsule, five feet from the speakers -
straight into a laptop.

This one is Bird on a wire, by Jennifer Warnes. It reveals the
less-than-ideal acoustics of my sitting room quite nicely. I have now
decided that I really must to something about the rather boomy bass,
even though I don't really notice it in normal listening.

Scary ain't it? - The first thing you notice is how *bad* the sound is -
nothing like what you hear yourself!!

Yup - I got rid of this one on Iain's advice. Copyright was still a
little too minty fresh...

What, like this do you mean?

This was a 'spur of the moment' *hand-held* grab to see what my little
digital *still* camera with 'video clip facility' (and hissy sound) would
make of the DTS soundtrack. I was quite surprised/impressed with it. Picture
quality suffers with the compression process more than the sound does, it
would seem!

(Be a bit quick with this one - I won't leave it up for to long, obviously!!
;-)

I know nothing about the choice between small and large diaphragm
capacitor mics for recording, as I've never recorded anything seriously,
but I have done very many measurements (for my employers over the years)
of loudspeakers, and wired and wireless telephone handsets of different
types. The measurement microphone for these was nearly always a B&K
4133 half-inch mic. Even though this is one of the flattest mics
around, it still has a considerable difference in its frequency response
above 15kHz when used pointing at the equipment under test, or used at
90 degree. (LS measurements tend to use the mic at 90 degrees).

This is simply due to the time taken for the signal to pass across the
0.5 inch diaphragm when at 90 degrees. The 1" mics show a much greater
difference in FR for 0 degree and 90 degree arrival signals.

Of course off-axis is one of the regions in which smaller is
definitely better. There is no defeating geometry.

Fine for measurement. Not so useful for music
recording;-))

Are you saying that you want a roll-off in HF for off-axis signals when
recording? (As someone who only uses microphones for measurement, I
don't know if this is the case or not).
