I don't have the resources for using REW, and even if I did it would require a learning curve that, at my age, I have no interest in.
Not sure how much effort it took to deliver me my answer on a platter, but I did express my appreciation, after all. I don't believe I argued with anyone except...
True, but again: DACs offer a variety of features, including many filter selections. Chord seems to offer unusually sharp cutoff filters with very deep attenuation, a feature that doesn't seem to get much run here.
Definition: static is invariant with time, whereas dynamic varies with time. In engineering one studies statics and dynamics as systems in this manner. That's why dynamics involves acceleration (unequal force), whereas dynamics involves none (balanced forces).
By the way, apparently this is...
The amplitude of an 8-Hz sine wave is indeed time variant. But if the amplitude and frequency both remain constant, I see the signal as static.
Perhaps the issue is that audio measurements can be both dynamic and static at the same time, depending upon what one is measuring.
You are limiting your discussion to the idea that amplitude varies in the time domain, which is obviously correct. But where I differ can be explained by an analogy: a vehicle traveling at constant velocity. Its position in XYZ obviously varies, but there is no acceleration. One can discuss the...
The fact that a sine wave varies in amplitude over time does not render it a dynamic phenomenon, if the frequency is invariant. Invariancy over time is the key element.
Life works like that: we operate in multiple dimensions. Chemical equilibrium is constant over the time domain so long as pressure and temperature are also kept constant. None of my questions arise out of a belief that "DACs have issues with strange signals." That's not relevant to my inquiry.
That's an interesting question that I don't have an immediate answer for. I guess I'd have to say if the pulse is identical over time, it could be regarded as static. But we're getting into semantics here.
Measuring output in the time domain of a component to a pulse input certainly is a...
