acoustic_indices: Get acoustic complexity values

In ARUtools: Management and Processing of Autonomous Recording Unit (ARU) Data

Get acoustic complexity values

Description

Wrapper for 'soundecology' package to calculate acoustic complexity, the bioacoustic index, and acoustic diversity. See Value for details about these indices.

Usage

acoustic_indices(
  path,
  min_freq = NA,
  max_freq = NA,
  units = "samples",
  quiet = FALSE
)

Arguments

path	Character. Path to wave file.
min_freq	Numeric. Minimum frequency for acoustic complexity (see soundecology::acoustic_complexity())
max_freq	Numeric. Maximum frequency for acoustic complexity (see soundecology::acoustic_complexity())
units	Character. Wave file units for reading the file. Defaults to "samples" (see tuneR::readWave()).
quiet	Logical. Whether to suppress progress messages and other non-essential updates.

Value

Returns a data frame with acoustic indices. Those prefaced with

• complx_ are from soundecology::acoustic_complexity()

• bio_ are from soundecology::bioacoustic_index()

• div_ are from soundecology::acoustic_diversity()

Examples

w <- tuneR::sine(440, duration = 300000) # > 5s
tuneR::writeWave(w, "test_wave.wav")
acoustic_indices("test_wave.wav")
acoustic_indices("test_wave.wav", quiet = TRUE)
unlink("test_wave.wav")
