// See top of file for a description of the algorithm.  Interpolates
// the samples from buffer[firstBad] through buffer[firstBad+numBad-1],
// ignoring whatever value was there previously, and replacing them with
// values determined from the surrounding audio.  Works best if the bad
// samples are in the middle, with several times as much data on either
// side (6x the number of bad samples on either side is great).  However,
// it will work with less data, and with the bad samples on one end or
// the other.
