Yes, there is a quite strong holographic error for capsule position deviations at low frequencies, as simulated in this thesis (p. 49): http://plessas.mur.at/rnd/da/Thesis_Plessas.pdf

In the paper I refered to used the researchers use a separate wireless sync signal to distribute word clock to all mics. See this paper as well: http://lac.linuxaudio.org/2014/video.php?id=13 which claims a sample accuracy of ~20microseconds. _______________________________________________ Sursound mailing list [email protected] https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
