Hello, I don’t understand very well the last calculation for the Speaker-to-speaker crossfade (Technical Details) in de Panning Tutorial (TUTORIAL 22: MSP).
¿First of all, why do we suppose b=1?
Then, I understand how to calculate the values, but when it says (Technical details in the tutorial help):
"Armed with all of this information, we can finally calculate the gain for the two channels as a cos(y±x)/d."
I don’t why do we arrive there. I would like to follow the steps in the middle to arrive to the gain formula.
In addition, I don’t understand the implementation in the MAX/MSP tutorial.
In the final expression: expr cos(($f2+$f4)*6.2832)*$f3/$f1*2/($f3+1)
What does it mean the end: … * 2/($f3+1) –> f3 is "a", it isn’t.
(I cant’t see the correspondence with the gain formula)
I hop you can help me!
Thank you so much!!
