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)
