generateNoise: 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"
)

Value

A list of Wave objects with the required noise added.

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?
