Slide the level from −48 to +100 dB and watch the amplitude and power ratios; the ×2 and ×10 buttons advance the marker by the same step every press.
The claim above is what this widget demonstrates. Disagree with it?
A level in dB is 20·log₁₀ of an amplitude ratio, so doubling the amplitude adds 6.02 dB and multiplying it by 10 adds 20 dB, from any starting level.
