Am I doing the right thing to convert decibel from -120 - 0 to 0 - 120

Question

I will like to measure the sound volume of the surrounding, not too sure if I am doing the right thing.

I will like to create a VU meter of a range of 0(quiet) to 12

Answer 1

Simply set your maximum and minimum value. Like you getting range of 0-120. If you want range of 0-60. Simply divide value to half to get the half range and so on..
