Interpolate

Description

Internal soundgen function.

Usage

interpolate(
  pitchCands,
  pitchCert,
  pitchSource,
  pitchCenterGravity,
  interpolWin_bin = 3,
  interpolTol = 0.3,
  interpolCert = 0.3
)

Arguments

`pitchCands`	a matrix of multiple pitch candidates per fft frame. Each column is one fft frame, each row is one candidate (the last row is always "manual")
`pitchCert`	a matrix of the same dimensionality as pitchCands specifying our certainty in pitch candidates
`pitchCenterGravity`	numeric vector giving the mean of all pitch candidates per fft frame weighted by our certainty in each of these candidates
`interpolWin_bin`	when interpolating pitch candidates, the median is calculated over `plus-minus interpolWin_bin`
`interpolTol`	when interpolating pitch candidates, the criterion for needing to interpolate is the absence of pitch candidates with values within `1 plus-minus interpolTol` of the median of pitch center of gravity over the interpolation window. For ex., if `interpolTol` is .05, we look for values from 0.95 to 1.05 time the median value over interpolation window.
`interpolCert`	when interpolating pitch candidates, all generated pitch candidates are assigned a certainty equal to `interpolCert`

Details

Interpolation: if a frame has no pitch candidate at all (NA) or no candidate between the most likely candidates for the adjacent frames, add such a candidate with some (low) certainty.
