When you have a table of samples with sample 1 and sample 2, but you are playing at a different speed so you need sample 1.7. Since this does not exist (it is between discrete values) you have to fake it.
TODO lanczos
TODO sinc
Lazy shit mode: just floor/ceil/round and use sample 1 or sample 2. Jagged waveforms and prone to aliasing but its cheap.
Linear interpolation: draw a line between sample 1 and sample 2 and take the value which is somewhere in between.
Creates a polynomial curve using the input and outputs of a function, then asks the function to synthesize the data.
Creates a polynomial curve using the derivatives of a function, then asks the function to synthesize the data.
