Message-ID: <4185@alice.UUCP> Date: Wed, 21-Aug-85 13:49:40 EDT Article-I.D.: alice.4185 Posted: Wed Aug 21 13:49:40 1985 Date-Received: Sat, 24-Aug-85 13:23:10 EDT References: <456@olivee.UUCP> <4150@alice.UUCP>, <424@azure.UUCP> Organization: New Jersey State Farm for the Terminally Bewildered Lines: 25 Kim Rochat demonstrates a typical sort of attitude for nut.audio, i.e. Rochat says: ".. discount all of your tests until you control absolute phase" (that's paraphrased, it's not worth dragging out of the file) This person then goes on to point out that absolute phase is a necessary condition for comparisons, and provides several references. All fine and dandy (and true), except for one thing: ABSOLUTE PHASE IS INDEED IMPORTANT, AND CAN MAKE TWO EXACTLY IDENTICAL SIGNALS (EXCEPT FOR INVERSIONS) SOUND NOTICIBLY DIFFERENT. WE DID NOT HEAR ANY SUCH DIFFERENCE, thus, by the publicly available information, the absolute phase must have been right :-(hey, fancy that, us people in NJ can actually do something right. Amazing, isn't it? :-( Furthermore, since Rochat knows that, Rochat can extract the answer to Rochat's own question. None the less, Rochat takes the popular view and attacks. Fascinating, isn't it? -- SUPPORT SECULAR TEDDY-BEAR-ISM. "I see a dark cloud, On the horizon,..." (ihnp4/allegra)!alice!jj
