“The volume level to set as a linear gain. 0 = silent, 1 = full volume.” quote from the Studio IPA reference. I wonder that the"full volume" mean 0db or 10 db? If it means 0db, should I setFaderLevel to 1.125 to make the volume equal to 10db?? (I presume 0 = -80, so 0.125 represent 10db) ---

The relationship is logrithmic, a doubling of the fader value is a increase of 6dB 1.0 = 0dB 0.5 = -6dB 0.25 = -12dB 0.125 = -18dB … 0 = -inf (silent) positive gains: 2.0 = +6dB 4.0 = +12dB Here is a calculator that does the conversion: > **[Decibel (dB) to Float Value Calculator - Making Sense of Linear Values in...](http://www.playdotsound.com/portfolio-item/decibel-db-to-float-value-calculator-making-sense-of-linear-values-in-audio-tools/?c=10)** > > TYPE IN YOUR VALUES TO THE BOXES BELOW \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ dB value to Float Value Converter (Type -100 dBFS to 0 dBFS) Linear Value Equivalent \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ Linear to d... ---

I realize how stupid my question is… I should be more professional, thx again.
