IsoMike™ ( “Isolated Microphones”) is an experimental acoustic baffle
system, to address the interference of inter-channel sounds that
results in compromised fidelity. For these 4-channel recordings,
the microphones were suspended on four arms, separated by
IsoMike baffles.  For stereo, only the front microphones are used – no mixing
Most baffles absorb sound from mid- to high-range frequencies;
lower frequencies are more difficult to absorb. Here, the unique
shapes of the IsoMike baffles are advantageous. As lower frequencies
flow around the heart- or egg-shaped baffles, they are
scattered, effectively dissipating their energy.
Eliminating line-of-sight between the microphones seems to
lower some fidelity robbing cancellations, this reveals a layer of
extreme detail and a sense of increased sensitivity. As such we
took great care, therefore, to reduce the noise level within the
auditorium during the recordings.
No compression No limiting  (no kidding)
