Replay gain finds that this title has a loudness of 78.56 dB. It will be encoded as 78.56 * 256 ~ 20111 = 0x4E8For float output (range [-1 1]), the max is 0.96. It will be encoded as 20 * log10(0.96 * 215) * 256 ~ 23029 = 0x59F5 (for peak values it is suggested to round to nearest higher integer)
e.g. A peak value of 23225 (read from the .mpc file) shows as a peak of 1.048776 in foobar; what's the calculation to go from one to the other?
