Oh, Gawd... Are we really getting into the dogs and bats argument again? The tests mentioned (live baffled vs. live direct musicians) cut off the high end response way below 20KHz, and probably way below 10KHz - and this in an era when the medium was hard pressed to reach 7KHz. Of course it made a difference - we can actually hear 10KHz. Now what this has to do with the 20KHz rolloff of CDs is beyond me. For all youse people that are still swayed by Linn Sondek's arguments, the latest issue of Audio has a very interesting article by Les Burwen entitled ``Confessions of a Digital Recordist''. This guy is SERIOUS about quality reproduction, and makes some very high caliber NR systems and line amplifiers through his company, Burwen Research. The upshot of the article was that the digital system he was using (Sony PCM F-1) sounded different and not as rich and full as his analog system BECAUSE OF INACCURACIES IN THE ANALOG SYSTEM. These errors amounted to +-1dB changes in the bass and treble, easily measurable and correctable. No other anomalies were noted save a slightly higher noise floor for the digital machine (!). As many other articles have noted, microphone techniques had to be slightly modified. -- Shaun Simpkins uucp: {ucbvax,decvax,chico,pur-ee,cbosg,ihnss}!teklabs!tekcad!vice!shauns CSnet: shauns@tek ARPAnet:shauns.tek@rand-relay
