.resample: Resample per sound

Description

Internal soundgen function

Usage

.resample(
  audio,
  mult = NULL,
  len = NULL,
  samplingRate_new = NULL,
  lowPass = TRUE,
  na.rm = FALSE,
  plot = FALSE,
  width = 900,
  height = 500,
  units = "px",
  res = NA,
  ...
)

Arguments

audio

a list returned by readAudio

mult

multiplier of sampling rate: new sampling rate = old sampling rate x mult, so 1 = no effect, >1 = upsample, <1 = downsample

len

if specified, overrides mult and samplingRate_new and simply returns a vector of length len

samplingRate_new

an alternative to mult provided that the old samplingRate is know (NB: mult takes precedence)

lowPass

if TRUE, applies a low-pass filter before decimating or after upsampling to avoid aliasing

na.rm

if TRUE, NAs are interpolated, otherwise they are preserved in the output

plot

should a spectrogram be plotted? TRUE / FALSE

width

graphical parameters for saving plots passed to png

height
