What are they? Part two of the question: some years ago, I read an interview with someone at Atari, who said that they had a new video game that used comb filters to remove phase information from sound output, which removed directional cues that the human ear/brain uses, so that the sound from this arcadge game seemed to be coming from all directions at once, rather than sounding like it came right out of the speaker. This seemed odd but interesting... can anyone shed any light on this? Is this something I could do with digitized sound on, e.g. an Amiga? Sorry to post to both groups separately but cross posting doesn't work here. Doug Merritt ucbvax!unisoft!certes!doug ("reply" doesn't work, so mail to the above)
