For any sinewave ( see Fourier theory for applicability ) the max slew rate ( at

For a 20kHz signal of say 2V peak amplitude that means a slew rate of 0.25 V/us
! Even a rubbish 741 or 1458 can manage that !

Given that modern audio op-amps are capable of slew rates of ~ 10V/us - you're
never even remotely close to slew limited anything.

Well, remember, the maximum slew rate found in audio signals is much
greater than what a theoretical 20 KHz signal is going to supply,


Utter drivel.

Learn some science before posting such ********.

bye bye.

I'll tell you what, why don't you take one point that you can attack,
ignore everything else, and then put out yet another unsupported
criticism. In audio, where you have a huge mixture of signals, the
waveforms periodically add together, momentarily increasing the slew
rate over what a typical -- read, very small amplitude -- audio 20 KHz
signal would have. Do you disagree with that? Would you like to state
here, for the public record, that you think that when several signals
are mixed, that there are no momentary peaks in slew rate which exceed
the maximum slew rate found in individual signals? By all means, show
everyone here how well you think, and reason, and how much you actually
understand about audio. Oh, BY THE WAY, do you have anything intelligent
and useful to say about the rest of my comments? Useless cheap shots do
not qualify ...
