morph: Morph sounds
In tatters/soundgen_beta: Parametric Voice Synthesis

Description Usage Arguments Value Examples

Takes two formulas for synthesizing two target sounds with soundgen and produces a number of intermediate forms (morphs), attempting to go from one target sound to the other in a specified number of equal steps.

1 2	morph(formula1, formula2, nMorphs, playMorphs = TRUE, savePath = NA, samplingRate = 16000)

`formula1, formula2`	lists of parameters for calling `soundgen` that produce the two target sounds between which morphing will occur. Character strings containing the full call to soundgen are also accepted (see examples)
`nMorphs`	the length of morphing sequence, including target sounds
`playMorphs`	if TRUE, the morphing sequence will be played
`savePath`	if it is the path to an existing directory, morphs will be saved there as individual .wav files (defaults to NA)
`samplingRate`	sampling rate of output, Hz. NB: must be the same as in `formula1` and `formula2`!

A list of two sublists ($formulas and $sounds), each sublist of length nMorphs. For ex., the formula for the second hybrid is m$formulas[[2]], and the waveform is m$sounds[[2]]

# write two formulas or copy-paste them from soundgen_app() or presets, for example:
m = morph(formula1 = list(repeatBout = 2),
          # equivalently: formula1 = 'soundgen(repeatBout = 2)',
          formula2 = presets$Misc$Dog_bark,
          nMorphs = 5, playMorphs = FALSE)
 # use $formulas to access formulas for each morph, $sounds for waveforms
 # m$formulas[[4]]
 # playme(m$sounds[[3]])
