Detailed Description

template<InterpolationMethod im = LINEAR_INTERPOLATION>
class InterpolatingSignalGenerator< im >

Signal Generator that generates an arbitrary number of in-between points, interpolated between two (linear, cosine) or more (cubic, hermite) reference points.

Can be used e.g. to convert a block rate signal to audio rate.
