[Hornlist] RE: Recording and Mic Placement

	There are also good, college-level textbooks about how to make 
recordings. One is John Eargle's Recording Engineering Handbook, 
which has been through three or four editions by now. These books 
cover more than classical music, more recent editions including 
how to do surround sound for video, and give much more detail 
about the theory, practice, laws of physics, and tradeoffs of 
each approach than is possible on an Internet mailing list.


	If you want to learn about the pros and cons of various microphone 
types, try to run down a copy of Gerhart Bore's little (79 p.) 
book entitled Microphones for Professional and Semi-professional 
applications, published by Neumann (but **NOT** advertising copy 
for them; this is cited in every book and article about 
microphones, I'm pretty sure including the Eargle book!) in 1989. 
He clearly explains the physics behind pressure and 
pressure-gradient transducers, large and small diaphragm mikes, 
and so on, again in a way that's beyond the scope of a mailing list.

[Hornlist] RE: Recording and Mic Placement (long)

	First, a little background about myself. I've been making 
recordings since about 1967. When I was in school I had a small 
business recording recitals, audition tapes (we used tape in 
those days ), and the like. My most recent recording was an 
audition CD for the Cleveland Orchestra. ("My" guy didn't win the 
audition, alas.) No one has ever complained about the sound I got.


	I have given serious thought to re-starting this business when I 
retire. I like to make recordings.


	In sum, if I could play as well as I can make records, I'd have 
had a major career.




Michael Ozment asks:

Lately, I have been trying to record myself more and more. I want to move
beyond just recording my practice sessions with a mini disc and a small
microphone. I have asked dozens of "recording" people about mics and variou=
s
recording equipment, but it just occurred to me that I should be asking
HORNISTS.



	You should ask people who have experience recording *classical* 
music. Recordings of classical music try to make the recordings 
sound as much like concerts as possible. The pop aesthetic, with 
which many engineers are most experienced, is just the opposite: 
they try to make the concerts sound as much like the records as 
possible.


	**THE** most important factor in getting good sound on a classical 
recording is the hall. If you don't have a good hall, just forget 
it, no matter how good your equipment. This is 85% of the result, 
no exaggeration. Microphone placement is probably the next 8%. 
Mike choice is about 5%, and the remaining 2% is *everything* 
else: tube vs. transistor, analog vs. digital, cable type, etc. 
I'd much rather record in Carnegie Hall with a Radio Shack 
cassette recorder and a pair of EV 635A's than in my (or your) 
living room with any megabuck German mike you can name. There 
just won't be any comparison.





What kind of mic do you use when recording yourself?



	If your only or principal use is to record your practice sessions, 
the mike you have now or some other cheap electret is probably 
more than adequate. If you're unhappy with what you have, I 
suggest trying a pair of Radio Shack 33-3013 lavalier mikes. They 
cost about $25 each, and you'll need an adaptor, also available 
at the Shack, to convert their 1/8" miniplug output to the stereo 
1/8" miniplug your minidisc will expect. If you don't like them 
you won't be out much.


	I've used the Radio Shack 33-3013 to record myself. They work 
fine. Mostly I use Neumann KM184's to record my practice 
sessions, but that's because I have them, they're easy to set up 
(read: don't need external power supplies), since I don't much 
like them I wouldn't shed too many tears if the stand got knocked 
over or a pipe leaked on them (I practice in the basement), and, 
frankly, why not, since I have them?





Or what kind of mics
have been used to record you in studio situations? Specific brands and
models would be more helpful than just "dynamic" or "condenser" Also, what
is the optimum mic placement for recording a solo horn?



	OK. Here's my list, in approximately ascending order of price. 
Please note that there is no one right microphone for any 
purpose, any more than there is the One True Horn or mouthpiece. 
Also note that I've had all the equipment I own for ages and so 
I'm not exactly up to date with prices; you'll have to do some 
research on your own. Taken as a whole, dynamic microphones will 
have lower output and worse transient response than real (i.e., 
not electret) condenser microphones. If you're using a minidisc, 
a condenser mike's output may overload the input (it doesn't on 
my Sharps, but you should check yours to be sure).


	In general, I prefer omnidirectional (aka omni, aka 
non-directional) mikes for recording classical music because they 
pick up more of the room sound. For unaccompanied horn you can 
space them about 16" on center, just like the studs in your 
walls, and get good results; for larger ensembles, like bands or 
orchestras, dividing the group in thirds with the mike stands is 
a good rule of thumb and first cut. How far back to put them 
depends on the hall. Position them to get the balance of direct 
vs. reverberant sound you (or the client!) like. You're doing it 
to your (or the client's) taste, and when you're happy, the sound 
is "right." There is no other right or wrong about it! Get a pair 
of Audio-Technica clothespin shock mounts and use them on 
everything but the Radio Shacks (which are too small to fit).


	All the mikes listed below have balanced output (3 pin XLR) except 
the Radio Shack 33-3013.



Omnis:


Radio Shack 33-3013: $25 each. Electret condenser. Requires a 
button battery for operation. Low current draw, so the batteries 
will die of old age before they run down. Very small, about the 
diameter of a pencil eraser.


Electrovoice (EV) 635A: $100 each. The quintessential ENG mike 
that you've seen on TV a zillion times. Indesctructable except by 
direct nuclea
