I am trying to use VU to measure the output of a signal. Is there an external like Max for [log~] or even [gain~]. ? I am trying to do the conversion db=log10(signal between 0 and 1)*20. Is there another way ? Thanks
Hi, I've been wondering about this: how does square root and logarithm work for signals, because signals may get positive or negative... which means taking square roots of negatives (imaginary result), taking logs of numbers very close to zero (big negative result), equal to zero (minus infinity result), smaller than zero (complex result)... I mean, the signal itself is not complex, so how does applying square root and then applying square get back to the original signal? (maybe the answer is: it doesn't...)
(note: i have not been trying those objects myself...)
