Without even listening, Keith, do yourself a favour and get a half decent
mic for this sort of test.

Lapel mics have a tailored frequency response to help with the fact that
they are in a poor position for speech. They have bass rolloff to counter
chest resonance, and mid range boost to try and improve intelligibility.
And often nothing at all at the HF end since it isn't necessary.

Just have a look at its frequency response...

There are a few 'wiseacres' here that know it all and will trot out the
stale, old 'FR drivers in horns have no top or bottom octave' hearsay
horse****.

Never mind the width.. What are the tracks Keith ?


No idea atm, Tony (and I'm late for outta here) - they are the end and
beginning of two consecutive trax on the 'The Abduction Of The Art Of Noise'
CD.

I could find them later....??

Thanks Keith, but that's enough to go on.. Explains why they sound
familiar and yet not at the same time..

If its of any use Keith, I can lend you a Behringer ECM8000 and home
made pre if you wanted to play further. I don't need it until I get a
couple of inductors wound.

OK, point(s) taken - my problem is I wouldn't know where to even start.
Every time I Google microphones I end up he

http://www.microphones.ru/

Then he

http://www.microphones.ru/downloads.htm

....and then get hung up on the downloads! (A couple of the topmost links
don't work, but the ones that do are so *beguiling* - start from the
bottom....!!! :-)


But I'm open to suggestions, Plowie - the ideal mic plugs straight into the
computer I suppose, but summat like this does have a certain appeal:

http://www.oktava-online.com/mkl2500.htm

Would that be suitable for piano recordings?? :-)

PS. Forget stuff like this:

http://cgi.ebay.co.uk/MANLEY-REFEREN...QQcmdZViewItem

http://cgi.ebay.co.uk/Neumann-M147-T...QQcmdZViewItem

:-)


But an opinion on these would be appreciated...???

OK, got those - ta!

But I'm not sure what use they are?? I merely wanted to demonstrate the
'dynamic range' of the Lowthers as I *hear* it - obviously, it ain't gonna
happen on the lapel mic!!

Assuming I get out in time, later/later (or maybe even tomorrow) I will

Oh you really aren't going to like the look of what that shows. Rooms
are just horrible.


OK, this is the CD track I intend to use - let me know if there's anything
unsuitable about it?

http://www.apah69.dsl.pipex.com/show/Tone%20Sweep.mp3


Also, can you confirm the start frequency - I have no trouble hearing it
from the very start, even on the computer setup with 2.5 inch drivers...??

Right, orf aht for a while now....




It starts out at 20Hz OK, but it really is unsuitable for the job. It
will spark off every standing wave in the room, and you really will be
shocked at how lumpy it is. Take up Nick's offer - it will be miles
better.

That sort of sweep is really only for internal testing of equipment,
not for rooms.


OK, forget that then. It looks like I'm going to have get summat sorted out
on the mic front.

OK, even I can see that ain't too *flat*!! (See other post re mics.)

That little Vivanco mic was virtually FOC from Glenn Booth - one the
'missing' from here these days!

It's a compilation of AON remixes by various artists:

I rate 60% of the trax good, 40% less so, but none of them *bad*...!!
