pathfinding_slow(pitchCands = pitchCands, pitchCert = pitchCert,
certWeight = certWeight, pitchCenterGravity = pitchCenterGravity,
manual = NULL, annealPars = list(maxit = 5000, temp = 1000))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")
a matrix of the same dimensionality as pitchCands specifying our certainty in pitch candidates
(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
numeric vector giving the mean of all pitch candidates per fft frame weighted by our certainty in each of these candidates
a dataframe of manual pitch candidates from pathfinder()
a list of control parameters for postprocessing of
pitch contour with SANN algorithm of optim. This is
only relevant if pathfinding = 'slow'
Optimizes the path through pitch candidates using simulated annealing with
optim. This can be really slow, depending on control
parameters.
