Re: [ARSCLIST] Microphone-in-horn discussion

[Susan T Stinson <ststinso@xxxxxxx>]

I have been following this discussion for a few days now and would like
to point out my observation (a large number of times, I should add) of
what Walter Welch did: he positioned the microphone so it aimed at the
center of the horn bell, and was about even with the bell's rim.  It was
not inside the horn - down into the narrower tubing, that is - which is
what I sense some of you have pictured.  It was still really outside the
horn, and so the room ambience would have entered into the results.
Comparison with other modes of playback, of course, would be needed to
determine its value.

Sorry if I did not answer before.

We were speaking about the problem concerning acoustic playback.

Well,
I think that if you record with the microphone into the horn you'll
capture all the inner horn reverberation.
The sound inside the horn is strongly compressed and its "evolution"
from the diaphragm to the horn end it's quite complex.
If you record into the horn many frequencies may not be at the right
volume or not audible at all.
Maybe recording in this way, due to the horn reverberation, may give a
sense ambience (as audiophiles call it) and make the recording
pleasant to be listen but I'm not shure it's correct.
I think that if you want the sound to be enriched by a natural reverb
(and not a reverb put in editing) it may be reasonable to record in a
good recording room.
