wigglePars: Wiggle parameters
In tatters/soundgen_beta: Parametric Voice Synthesis

Description Usage Arguments Details Examples

Internal soundgen function

1	wigglePars(parList, parsToWiggle, probMutation, stepVariance)

`parList`	full list of considered parameters
`parsToWiggle`	a list of the names of pars that might be mutated
`probMutation`	the probability of a parameter mutating per iteration
`stepVariance`	scale factor for calculating the size of mutations

Helper function for matchPars. Takes a list of control parameters for soundgen and introduces some random variation in their values.

soundgen:::wigglePars(
  parList = list(
    sylLen = 250,
    pitchAnchors = data.frame(time = c(0, 1), value = c(200, 300))
  ),
  parsToWiggle = c('sylLen', 'pitchAnchors'),
  probMutation = .75,
  stepVariance = .5
)
