Y = 21.148ln(x) - 199.66, where y is dB and x is a linear value between 8īut that formula seems totally wacko - even though it has an r^2 of 0.997. The relationship between magnitude and decibels is ydb 20 log 10 (y). I tried reverse engineering it, by building an x, y scatter plot and i get: ydb mag2db(y) expresses in decibels (dB) the magnitude measurements specified in y. Decibel - Wikipedia, the free encyclopedia This is the first Ive ever seen anything else like that.

GainMarginsdB mag2db (m.GainMargin) GainMarginsdB 1×2 -9.3510 10.6091. Hmm, whoever wrote the wikipedia page seems to agree with what Im saying about 10log(A) being a conversion from linear to dB scale, while 20log(A) converts between amplitude gain on the linear scale to power gain on the dB scale. Hopefully, someone who touches the code can copy and paste the formula. Note that gain margins are expressed as gain ratios and not in decibels (dB). If youve only got 0.5 mW output, then the ratio is 0.5e-3/1e-3 0.5. It's labels don't conform to cakewalks - it just sends an receives an integer between 8 . For power, as shown in your plot, the reference is 1 milliwatt (denoted from the dBm). Once can approximately measure the linear location of each label (-24, -12, -6, 0 etc.).ĭoesn't even closely resemble the formula!Ĭakewalk seems to have its own logic.and that's what I'm trying to get some insight into. If you do a screenshot of the cakewalk fader strips, they go from INF to +6.

(The mackie isn't the issue, its Cakewalk). This function converts a decibel value into the linear ratio between two voltages or powers. Unfortunately, while you are correct about the "standard", cakewalk doesn't seem to use it. I can't remember if the Mackie does any scaling at all for the fader values before it sends out or not, but the formula for going between a linear & db scale is pretty standard:
