This could work up to the frequency for which the distance between the mics would be 1/3 of the wavelenght or so. Given the OZO's size that will be way too low. And for lower frequencies such a differential mic requires a gain rising by 6 dB for each octave down. A S/N ratio of 64 dB means 30 dB SPL self-noise, so these mics (most probably MEMS) will be very noisy even without taking such processing gain into account. The OZO is meant for professional use, and with these audio specs it is clear that for such use the audio will in almost all cases be recorded by other (higher quality) means. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
