could also be used for recording, and reproduction. Onfotunately the standard array mics are a little noisy for music recording and a high quality low noise microphone would e costprohibitive at Qty 90.
And yes Blumein array is -IMO a nice recording technique - especially useful for the ambience feed to a recording or medium sized live events in the somewhat near field. A second (or 3rd) X-Y array can be used with appropriate delays to mix in ambience from the rear of the hall. For engineered recordings, M-S mic configurations for the individual performers and instruments are great - you can "place" the track anywhere adjusting the levles and delays relative to other tracks and the mix down to Mono is honest.
Three most important things in Audio reproduction: Keep the noise levels low, the power high and the room diffuse.

ABOVE is a reference to Belafonte at Carnege Hall... As being a stereo recording... IT IS NOT and the photos at the performance shows that,,, Harry is holding one mic and walking back and fort on stage,,,His band has two mics close to the floor not even matched spaced a couple of feet apart... Two other mics above his head are faceing away from his body tward the back of the stage,, A string section is grouped in another position on stage,,, NO imageing is produced,,,Also WHAT IS MOST INTERESTING ALL APPLAUSE SEEMS TO COME FROM THE FRONT ON STAGE WITH BELAFONTE,,...
about the applause coming from the front? You just pointed out how the mikes were placed. If they were cardioid types, that is to be expected.

The mics in the Belafonte concert are not pointed at the audience,,So how did the audience appear in front of you in reproduceing the mix of the recording.. When Belafonte asks the sections of the audience to respond,,Why did the section NOT give proper locolazation cues on the record ??
mountains of molehills.
If the mikes are omnis then the phenomenon you mention has an obvious explanation.
If the mikes are your typical cardiod pattern, which is a heart shaped pattern with the indentation being at the mike, you are capturing the sound off the sides and slightly to the rear.
Now take applause: can you identify individual people clapping? I don't think so. Applause is basically random noise and it literally echoes off the sides of the venure. Directionality concerning applause is basically impossible, not to mention that you have tremendous issues with phase, particularly wince applause tends to have severe "bounce" off side walls.
A normal mike will pick up a lot of the applause as it echoes off the side walls and the reflectors over the performers. The mike can not distinguish individual people clapping ( at lest for normal clapping) and so your ears perceive the clapping as being being all around.
Next time, try standing on a stage while the audience is clapping. The sound completely engulfs you, even if you are on stage.
If you want to hear applause as it should try a discreet four channel recording, like Kimber's Iso mike recordings.

The mics are in the photos and the manufacture can be identified..plus what way they are pointed,,So STEREO claimes are false....BELAFONTE is Obviously MONO..
All stereo recordings employ at least two mikes. What's wrong with more and then having to mix them down?
In a live performance, you can't have just two fixed mikes as the solo performer is moving around on stage. It isn't a studio. Concessions must be made to accommodate the performance.
Stu
There is a mono version of Belafonte at Carnegie Hall, but the stereo version actually is stereo, as in RCA Living Stereo.
Yes I know that...I have both,, But it does not answere my question.. RCA is pulling the wool over your eyes claiming a full stereo recording,,When on stage,,A full stereo mic setup did not exhist,,
