Add noise to a Wave like object — generateNoise • sonicscrewdriver

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"
)

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?

A list of Wave objects with the required noise added.
