dot-addAM: Add AM to a sound

In soundgen: Sound Synthesis and Acoustic Analysis

Add AM to a sound

Description

Internal soundgen function, see addAM.

Usage

.addAM(
  audio,
  amDep = 25,
  amFreq = 30,
  amType = c("logistic", "sine")[1],
  amShape = 0,
  invalidArgAction = c("adjust", "abort", "ignore")[1],
  plot = FALSE,
  play = FALSE
)

Arguments

audio	a list returned by readAudio
amDep	amplitude modulation (AM) depth, %. 0: no change; 100: AM with amplitude range equal to the dynamic range of the sound (anchor format)
amFreq	AM frequency, Hz (anchor format)
amType	"sine" = sinusoidal, "logistic" = logistic (default)
amShape	ignore if amType = "sine", otherwise determines the shape of non-sinusoidal AM: 0 = ~sine, -1 = notches, +1 = clicks (anchor format)
invalidArgAction	what to do if an argument is invalid or outside the range in permittedValues: 'adjust' = reset to default value, 'abort' = stop execution, 'ignore' = throw a warning and continue (may crash)
plot	if TRUE, plots the amplitude modulation
play	if TRUE, plays the processed audio
