generateNoise: Add noise to a Wave like object

In sonicscrewdriver: Bioacoustic Analysis and Publication Tools

Add noise to a Wave like object

Description

Adding noise to a Wave like object allows for testing of the robustness of automated identification algorithms to noise.

Usage

generateNoise(
  wave,
  noise = c("white"),
  noise.add = FALSE,
  noise.ratio = 0.5,
  noise.ref = "file",
  output = "list"
)

Arguments

wave	Object to add noise to (Wave, WaveMC, or Tagged versions), or a list of such objects.
noise	Vector of noise to add (unif, gaussian, white, pink, power, red)
noise.add	If TRUE all noise sources are added to wave. If FALSE separate outputs are created for each noise source.
noise.ratio	Ratio of maximum noise amplitude to the maximum amplitude in wave.
noise.ref	Reference maximum for noise.ratio. If "max" then the maximum amplitude, if "file" then the maximum amplitude of wave.
output	TODO: Is this implemented?

Value

A list of Wave objects with the required noise added.
