Internal soundgen function.
1 | costPerPath(path, pitchCands, pitchCert, certWeight, pitchCenterGravity)
|
path |
evaluated path through pitch candidates (as integers specifying the rows in pitchCands, not the actual values of pitch) |
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 |
Internal helper function for postprocessing of pitch contours called by
pathfinding_slow
. Calculates the cost of a particular path
through pitch candidates based on pitch jumps and distance from
high-certainty candidates.
