How Perpetual defined interpolation was in the same context as normal interpolation. It's in layman's terms using adjacent samples to determine the values of the oversampled components. With the use of a "window" that consists of a set of coefficients, which depict a time-truncated filter function. This 16/44 signal is convolved digitally with the coefficient set to calculate (or interpolate) the oversample values.Extrapolation is predicting future values based on existing data. (Stock analysts use "extrapolation" to predict the market and various stocks.) It differs from interpolation which fills in values *between* existing data points.
