Make Signals Work (Modulation, Range, Translation, Application, Interpolation)

signalWork.js

// make a signal do what you want it to do
//

// LFO manipulation
// (assume the signal ranges from -1 to 1)

// make the value range 0-1 (no negative numbers, aka unsigned)
var destination = (signal + 1) / 2;

// adjust another number/value using the LFO signal
var destination = initialVal + (signal);

// same as above, but with +/- 0.5
var destination = initialVal + (signal/2);


// scaling methods

// squash or stretch a source signal to a destination range
var source = signal;
var sourceRange = sourceMax - sourceMin;
var destinationRange = destMax - destMin;
var destination = destMin + (destinationRange)(source - sourceMin) / (sourceRange);
