  min_percentile = 0.75,
  max_na_prop = 1
)

Arguments

fmt	Either F0 or formant frequency (in Hz). Default: fmt = 0.
min_points	Minimum number of points for audio section. Default: min_points = 4.
min_percentile	Minimum percentile value of gain to be included on the average of fmt. Default: min_percentile = 0.75.
max_na_prop	Maximum proportion os NAs on gain sector. Default: max_na_prop = 1.

Examples

library(voice)
# get path to audio file
path2wav <- list.files(system.file('extdata', package = 'wrassp'),
pattern = glob2rx('*.wav'), full.names = TRUE)
# Media dataset
M <- extract_features(path2wav)
assign_notes(M, fmt = 0) # f0
assign_notes(M, fmt = 1) # f1
assign_notes(M, fmt = 2) # f2
