If you take the absolute value of the FFT output, does that give you the amplitude?(adsbygoogle = window.adsbygoogle || []).push({});

I am asking because I have seen example where that is taken as the amplitude, and examples were the absolute value is multiplied by either SQRT2 or by 2 to get the magnitude.

So my question is what is right? How do we get the exact amplitude? and if magnitude means the same as amplitude in this context?
