This is an experiment in a new way of recording hard-to-record music such as orchestras, jazz bands, choirs, pipe organs, pianos, harps, ensembles, and quartets etc.
This invention is called an IsoMike� Baffle (short for Isolation Microphone) and is designed to isolate the right and left microphones from "seeing" each other. The design of the baffle is from a theoretical idea about how the right and left channel sounds will interfere with each other, resulting in poor recordings.
There are microphones on the two arms that are hanging down, between the microphones is a large heart-shaped baffle. There are also two smaller heart-shaped baffles positioned in a behind/below position. There is a complex mechanical design under the fabric shell of the baffles, which takes well over 100 hours to construct.
The baffle construction is designed to absorb sound from a medium to high pitch or frequency. Below that medium pitch, sound energy is not so easy to absorb, that is where the shape of the baffle becomes effective. As those lower frequencies flow around the baffle they encounter the heart shape which scatters energy, which is as effective as absorbing energy. The smaller baffles are to control the amount of energy that will reach the microphones from the back of the auditorium.
The result is that the microphones can be much more sensitive, in fact if you are within about 50 feet of the microphones a quiet conversation would be clearly recorded.
