That is very intensive processing. Precise spacing/positioning of the
capsules must be involved as well. I see that Soundfield claims the
B-format signals produced by their mics "are corrected to provide
nearly-flat frequency responses for sounds arriving from all
directions." Looks like I'll need an extra pair of socks to check out
these systems. Rob D.
