make_band_chimeras: make_band_chimeras

In abeith/chimeRa: Create Auditory Chimeras with R

Description

make_band_chimeras Synthesize and store single or multi-band auditory chimeras from pair of original signals.

Usage

make_band_chimeras(
  x1,
  x2 = "noise",
  f = 1,
  n_bands = c(1, 8, 32),
  savepath = ".",
  bitrate = 16,
  refilter = FALSE,
  save_waves = TRUE,
  do_plot = FALSE
)

Arguments

x1, x2	original signals. Can be a numeric vector or object of class "Wave"
f	sampling rate in Hz. Not required if using a "Wave" object. Must match for both signals.
n_bands	Number of frequency bands used for synthesis. Can be scalar or vector, in which case one pair of chimeras is synthesized for each element of n_bands.
savepath	path to folder where chimeras will be saved
bitrate	bitrate of signal. 16 used as default, if "Wave" object is used bitrate will be extracted from x1
refilter	set to TRUE to filter again after exchange operation (default FALSE). Not tested.
save_waves	if FALSE waves will be returned in a list
do_plot	plot spectrograms of chimeras. Not implremented.

Value

wav files of chimera pairs for each band in n_bands
