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.

I tried reverse engineering it, by building an x, y scatter plot and i get: Hopefully, someone who touches the code can copy and paste the formula. It's labels don't conform to cakewalks - it just sends an receives an integer between 8 . 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. Background The deciBel or dB scale is a convenient way to represent both large and small numbers. If you do a screenshot of the cakewalk fader strips, they go from INF to +6. (The mackie isn't the issue, its Cakewalk). Each application has its own suffix (i.e. For many applications of the decibel, there are standardized reference points for defining 0 dB in absolute terms. Unfortunately, while you are correct about the "standard", cakewalk doesn't seem to use it. Decibels can be used to describe quantities that relate to many things, including light, sound, radio waves, and electricity. The lowest (quietest) sound on a decibel scale, which is considered near-complete silence, is 0 dB. To convert from decibel measure back to power ratio: P2/P1 10 (A/10) Voltage is more easily measured than power, making it generally more convenient to use: A 20log10 (V2/V1) (Z2. 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: A 10log10 (P2/P1) (dB) where P1 is the power being measured, and P1 is the reference to which P2 is being compared.
