In edwbaker/SonicScrewdriveR: Bioacoustic Analysis and Publication Tools

Compute the acoustic activity index using scikit-maad

Description

For addition documentation see https://scikit-maad.github.io/generated/maad.features.temporal_activity.html \insertCitetowsey2013sonicscrewdriver.

Usage

maad_temporal_activity(
  wave,
  dB_threshold = 3,
  mode = "fast",
  Nt = 512,
  maad = NULL
)

Arguments

wave	A Wave object.
dB_threshold	dB threshold of activity (default = 3).
mode	Mode of the envelope calculation. Can be "fast" or "Hilbert".
Nt	Size of each frame. The largest, the highest is the approximation.
maad	An optional maad object. If not provided, one will be created using getMaad().

Value

List of calculated values, comprising:

ACTfrac	fraction)of points above the threshold for each frequency bin.
ACTcount	total number of points above the threshold for each frequency bin.
ACTmean	mean value (in dB) of the portion of the signal above the threshold.
