get_serial_anchors

Convert a set of point anchors to a set of anchors that prevent overlaps while fixing the retiming factor within words.

get_serial_anchors(
  anc_in,
  anc_out,
  w_onsets,
  w_offsets,
  fs = NULL,
  retime_f = NULL,
  dry_run = F,
  smudge = 0
)

Arguments

anc_in: a vector of time points in the input signal
anc_out: a vector of the times anc_in should be mapped to in the output signal
w_onsets: a vector of time points for the onsets of words. Should be same length as anc_in.
w_offsets: a vector of time points for the offsets of words. Should be same length as anc_in.
fs: Sample rate of signal. If provided, returned anchor points with be expressed in samples. If NULL result will be expressed in seconds.
retime_f: The desired factor that words should be sped by. If NULL the minimum change in rate that will prevent overlaps will be calculated.
dry_run: If TRUE function will exit early with the minimum factor that will prevent overlaps.
smudge: If > 0 this applies a crude adjustment to the calculated anchors to ensure monotonicity. Not necessary unless w_onsets are same as previous w_offsets.

A list that can be used to perform retiming with the wsola function of this package.
