I've said it before (in-between one of my long rants), but I'll say it again: most likely most matrix encodings, whether active or passive, could be recognized blindly with the proper digital signal processing. I've never tried it, but there is plenty of theory to support it, and in more than one way. For example, if you can ever lock onto a single source which gives out even a single, sustained harmonic which slides slowly enough in frequency, it is possible to calculate the local form of the transfer function from the source to the recording from there. Or if you ever know some source is impulsive enough, it's possible to use it as a bootstrap for multichannel deconvolution, where reverb is an aid to detection, instead of a hindrance. And so on. I've never done it, but it's eminently doable. I wouldn't be surprised if it was doable, with whole pieces, to the level of identifying individual encoding circuits, or at least their faults, instead of just encoding standards. I mean, we have a *stupendous* amount of prior knowledge available about what music seems like when viewed through mathematical-statistical indicators, whereby seeing which kind of a system they went through before landing in our hands as an encoded version ought to be a rather straight forward (if modelling and computation intensive) problem. -- Sampo Syreeni, aka decoy - de...@iki.fi, http://decoy.iki.fi/front +358-50-5756111, 025E D175 ABE5 027C 9494 EEB0 E090 8BA9 0509 85C2 _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
