Quote:Sound is not really analog though to start with.
Sound is simply a set of compressions and rarefactions in air. We hear by these by the effect of them vibrating our eardrums and sending a set of discrete nerve pulses (nerves have latency so there is no instantaneous generation nor recovery from pulsing) so it is not truly continuous even at the ears. An analog microphone contains a membrane that vibrates (like a speaker in reverse) and moves a magnet within a coil (or vice versa) generating a voltage, again these are discrete pulses and while they may look continuous they really cannot be by definition. So really sound is much less analog to start with and recordings (analog or digital) are by definition approximations of the source...
I do agree with you, but then , I don't!
Your first sentence is not right, analog is a continuous movement of air, transferring these movements to our ear which is analog by definition!
All the other possible sources of signal conversion management errors is there, always have and always will be!
Just now, in the recent years, another way of defining audio signals have been introduced.
Some programmers writing code defining "their" personal perception of how audio should be perceived.
So sound is from the start analog, I do disagree with you there!
But from there on, "approximations of the source", we do agree about.
What does the word analog mean ?
