In my last response to you I stated "It has been explained to you that sound waves loose high/ultrasonic frequency over distance/time ..."and previously I stated that "what we sample is amplitude over time" so clearly I am considering the time domain and your statement is FALSE!!Gregorio, you really didn't understand what I mean because you don't seem to consider what happens in the time domain.
Again, what we sample is amplitude over time, that's it, nothing else!!To understand what a waveform is we not only need to consider which signals are audible, but we also have to look at their position in the time domain.
So going back to my previous post, what you're effectively saying is that "yes a violin placed on a stage will start (randomly) playing itself but not random frequecies, it will always sound like a violin, not a piano or the spice girls. You still confident in that are you?Frequencies are not random, but their position in the time domain is random.
No it's not, most people do not think a violin could randomly start playing itself. I don't really know what most people think but I don't need to, the complexity of the waveform can easily be analysed. And don't forget, much of this isn't new science it's some of the oldest, most well established science we have. Pythagoras discovered the mathematical relationship of music notes/harmonics around 2,500 years ago!This is what makes the waveform more complex than what most people think.
Some are, some aren't. If none were audible music wouldn't exist, we wouldn't hear pitch or in fact any sound at all!Then, we have to consider that frequencies in the waveform are not really audible.
That obviously cannot be correct because sound is defined by it's frequency content. If a sound has no frequency content then it isn't sound!They are not what we use to call sound but only information about sound.
Have you been reading too much metaphysics? Somehow I don't think so. According to you, sound is produced mathematically and randomly, now you're saying the ear produces the sound. So the human ear must be a random mathematical machine! Great, why stop at sound science when we can completely mangle the science of biology and anatomy as well! And, how can recording work? If it's the ear producing the actual sound then we would have to put our microphones next to the ear rather than next to the musical instrument that's being played. If there's lots of people listening to a concert, who's ears do we record? How much confidence do you have in your assertion?This information has to be computed by the ear to produce actual sound.
