Oohashi's paper is widely revilied ...
"At least" that is neither as egregious nor prevalent as arnylied |

How ever could we measure how inaudible high frequency sounds affect the listener? you ask. Since you know about a study titled "Inaudible High-Frequency Sounds Affect Brain Activity" one could assume you'd make that connection. And you didn't dispute so much as reject the findings. Wrong, I've deconstructed the paper and shown where the procedures were grossly flawed. Some tut-tutting about the possibility of intermodulation distortion is about all I see. If anybody rejected anybody's findings Stephen, it is you who have rejected but not ever properly responded to mine about Oohashi. You don't reject the findings? Still, if you have more than the IM thing, repeat or cite it and I'll show that I understand your objections. Oohashi's paper is widely revilied and discredited. I'd be interested to see the peer-reviewed follow-up that "reviles and discredits" the article. Stephen |

Recording engineers using tape would usually push recording levels up into
the red.. This produced a saturated effect on the tape somewhat similar to a compression type effect. This produced a warm, full sound. Try to push the levels into the red with digital and you just get clipping. "Arny Krueger" wrote in message ...

He replied as follows, however I'm wondering if others agree with his assessment? You know we could get into a lot of technical gobbledygook as the forums often do but the bottom line is how do you like the way it sounds? Digital has many advantages over analog but I think all of us oldtimers find the analog sound to be warmer and more pleasing in a number of ways. Ultimately that's the test. So ultimately we may ask a string quartet to perform through a veil to make it sound like analogue recording ? geoff This is very witty, but though I don't advocate a return to LPs I can understand what about them attracts people. Yup sentimentality and ears that are far enough gone so that they don't hear all of the bad stuff that the LP format adds. When I listen to a live orchestra in the concert hall it somehow sounds "analogue' to me, not digital. Speaks to your unfortunate experience with bad digital, Paul. In other words, I don't hear treble "glare" nor experience listener fatigue. Time to upgrade your system, Paul. And ultimately live music has to be the criterion. It's like Paul even knows what real-world live music sounds like, even in his dreams. |

![]() "Arny Krueger" wrote in message ... It obviously does matter. While one ear is deaf to the effect of sound above 20kHz or so, two ears are differentially sensitive to 50 kHz or more From http://web.mit.edu/2.972/www/reports/ear/ear.html, the ear is sensitive to the difference of arrival time of a sound to each ear to 10 microseconds. Quoting, "The brain is sensitive to differences in time of arrival of as small as 10 microseconds, and can use this to pinpoint the location of the sound." This corresponds to a steady state tone of 100,000 Hz. Inability to tell the difference between a well-documented fact and an unsupported assertion, noted. This is not a paper that has been referred or published in a professional journal. It's just a class report for an undergraduate class called "How Things Work". Here's the home page for the class: http://web.mit.edu/2.972/OldFiles/www/body.html It has no proper footnotes, just some broad references. Rather than arguing the merits of the paper why address Moreins grossly flawed logic. Maybe in terms you and he can understand.... the situation is this. Consider the brain as a high bandwidth scope...easily capable of measuring ITD or IPD in the range of 10 usec. But it is has 2 bandwidth limited mics feeding its inputs called ears. Now just because the brain can resolve 10 usec time or phase delays has no real bearing on the bandwidth of the ears. ScottW |

I need to follow up on the psychophysical info but the physiology
seems to make it unlikely that there is temporal (rather than a phase) discrimination of such brevity, an aspect acknowledged in the review.

I just found an interesting review article:
http://www.physiol.ox.ac.uk/~raac/pd...aa_curBiol.pdf I get the impression that you are correct, that these are phase differences. If this is the case, it is rather misleading to refer to "arrival time differences." In the case of a steady state tone, it doesn't arrive, it is simply present, and an accurate term for the faculty would be phase discrimination. I haven't found any web references to the localization of impulsive sounds, as opposed to steady-state tones. If you find anything on localization of impulsive sounds, please post.

It was/is common PRACTICE to drive the signals and saturate the tape. This gives more 'headroom' than digital (thus greater dynamics). If you listen to this phenomenon on analog recordings (analogue recorded vinyl on good equipment) you will find it has a warm effect and will not sound flawed. Digital, however, has virtually no 'headroom'. If distortion occurs it is very brash and sounds very flawed. "Digital preserves music the way that formaldehyde preserves frogs.

It was/is common PRACTICE to drive the signals and saturate the tape. It can't be common practice any more, because hardly anybody still uses tape. What people did when tape was all they had is pretty irrelevant here, more than 20 years later. This gives more 'headroom' than digital (thus greater dynamics). Horsefeathers, tape does not give more dynamics than good digital. If you mean that distorted sound tends to sound "louder" than undistorted sound, then that's true, but so what? If you listen to this phenomenon on analog recordings (analogue recorded vinyl on good equipment) you will find it has a warm effect and will not sound flawed. You call it warm and unflawed, I call it what it is - distorted. Digital, however, has virtually no 'headroom'. Horsefeathers. Good digital has far more dynamic range, and therefore its far easier to run with lots of headroom. If distortion occurs it is very brash and sounds very flawed. If you can set levels to avoid that, how incompetent are you, anyway? "Digital preserves music the way that formaldehyde preserves frogs. You kill it, and it lasts forever." Nonsense. The worst thing that can be said about good digital is that the signal that is played back is indistinguishable from the signal that was recorded. |

Arny, in support of your point, I relate the following. I have been using a Sound Devices 744T to record musicians in public places in NY. I've made a number of beginner's mistakes. But with two stage optical limiting, and immense headroom in the mike circuits, the sound is still impeccable. A friend of mine, a tubophile, remarks that it doesn't sound like solid state. It doesn't sound like anything. It is simply a superb recording device. |
