maad_spectral_activity: Compute the spectral activity using scikit-maad

In edwbaker/SonicScrewdriveR: Bioacoustic Analysis and Publication Tools

Compute the spectral activity using scikit-maad

Description

Acoustic activity corresponds to the portion of the spectrogram above a threshold frequency per frequency along time axis \insertCitetowsey2017sonicscrewdriver.

Usage

maad_spectral_activity(object, dB_threshold = 6, maad = NULL)

Arguments

object	A Wave object or a spectrogram_maad object.
dB_threshold	dB threshold of activity (default = 6).
maad	An optional maad object. If not provided, one will be created using getMaad().

Value

The function computes for each frequency bin:

ACTfract	Proportion (fraction) of points above the threshold.
ACTcount	Total number of points above the threshold.
ACTmean	Mean value (in dB) of the portion of the signal above the threshold.
