sorry for being unclear, i was joking with words... what i'm looking for is exactly the behaviour i get from a stereo correlation meter (or the W-X one for that matter), where negative means out-of-phase, zero means mono and positive means stereo'ish. my intent is to be able to tell at a glance whether a signal has lots of X, Y, or Z information. for instance, i would expect the Y and Z meters to linger around 0 for an open-air recording of a single musician at the same elevation as the microphone. Z would move to 1 when a plane flies overhead (or a subway rumbles below), and Y would indicate sounds coming from off the median plane. regards, jörn -- jörn nettingsmeier home://germany/45128 essen/lortzingstr. 11/ http://spunk.dnsalias.org phone://+49/201/491621 Kurt is up in Heaven now. _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/mailman/listinfo/linux-audio-dev
