Convert a gain ratio into decibels for level planning.
Decibels compress huge ratio ranges onto a log scale, using twenty times the logarithm for amplitude and ten times for power. Consoles, plugins and meters all speak in decibels, so translating a linear ratio into dB makes level changes comparable everywhere.
Decibel Gain
dB = 20 x log10(ratio) for amplitude; 10 x log10(ratio) for power
