What is spectral interpolation?
An analysis/synthesis technique in which a musical tone is modelled as a set of harmonics with slowly varying amplitudes. As long as amplitudes vary relatively slowly, linear interpolation between wavetables provides an efficient synthesis technique.
Is spline interpolation better than linear interpolation?
Linear interpolation gives the highest average difference, while spline interpolation gives a somewhat lower difference than polynomials. We also notice that a polynomial of degree 4 has a larger average error than a polynomial of degree 3.
Which is better regression or interpolation?
In summary, interpolation provide better accuracy in the value of y within the domain of a known x range while regression provides better predictions of y in the domain below and beyond the known range of x.
Why do we use linear interpolation?
Linear interpolation is useful when looking for a value between given data points. It can be considered as “filling in the gaps” of a table of data. The strategy for linear interpolation is to use a straight line to connect the known data points on either side of the unknown point.
