Sorry, I am not sure if it’s right place to ask such things, but due to fact a lot of us work with audio plugins I decided to ask it. And lot of you could ask for what I ask such things, why I need it? So I answer in advance: I just want to know it
It also could be handy when naming some variables or methods in programming. But the main reason is “I am just inquisitive”. Does it make a sense?
But to the point:
According to definition of decibel it’s “logarithmic unit of measurement used to express…bla bla bla”
So in audio we often convert linear value from range 0 to 1 to logarithmic scale for example like that:
double result = 20.0 * log10(valueInRange_0_1)
(of course we need to menage situation when
valueInRange_0_1 = 0, but leave it now, it’s not the case)
So for example for
valueInRange_0_1 = 0.5 result will be about -6 and we can call it “-6 decibels”.
But the question is how we can call
valueInRange_0_1 = 0.5:
“0.5 OF WHAT” ?
I know in audio we can call it “0.5 gain”, or “0.5 of linear value”. But is there any general term to use as opposite to decibel?
