Internal soundgen function.

1 2 |

`pitch` |
numeric vector representing our best guess at pitch contour, which we are now attempting to improve by minimizing its elastic tension |

`pitchCands` |
a matrix of multiple pitch candidates per fft frame. Each column is one fft frame, each row is one candidate. |

`pitchCert` |
a matrix of the same dimensionality as pitchCands specifying our certainty in pitch candidates |

`certWeight` |
(0 to 1) in pitch postprocessing, specifies how much we prioritize the certainty of pitch candidates vs. pitch jumps / the internal tension of the resulting pitch curve |

`pitchCenterGravity` |
numeric vector giving the mean of all pitch candidates per fft frame weighted by our certainty in each of these candidates |

`snakeStep` |
optimized path through pitch candidates is further
processed to minimize the elastic force acting on pitch contour. To
disable, set |

`snakePlot` |
if TRUE, plots the snake |

Internal helper function for postprocessing of pitch contour. Wiggles a snake along the gradient of internal + external forces. NB: if the snake is run, the final contour may deviate from the actually measured pitch candidates!

Returns optimized pitch contour (numeric vector of the same length as
`pitch`

).
