DetectBLED

Description

Function to do band-limited energy summation to find sound events. This function only identifies sound events based on frequency and duration so is not expected to have high precision.

Usage

DetectBLED(
  input,
  input.type = "wav",
  min.freq = 200,
  max.freq = 6000,
  noise.quantile.val = 0.75,
  spectrogram.window = 1600,
  subsample.dur = 300,
  training.label = "noise",
  pattern.split = ".wav",
  min.signal.dur = 1,
  max.sound.event.dur = 6,
  wav.output = "TRUE",
  output.dir = getwd(),
  swift.time = TRUE,
  time.start = 18,
  time.stop = 23,
  write.table.output = TRUE,
  verbose = TRUE,
  random.sample = 100
)

Arguments

input	Either full path to directory containing .wav files or a list with file name as first element and .wav as second element
input.type	Either 'directory', 'list' or 'wav'
min.freq	Minimum frequency (Hz) of signal of interest
max.freq	Maximum frequency (Hz) of signal of interest
noise.quantile.val	A quantile value between 0 to 1 for the band energy summation
spectrogram.window	Window length for spectrogram analysis (input to spectro fuction from 'seewave')
subsample.dur	Duration (s) to divide longer sound file to increase processing efficiency
training.label	Label to append to saved .wav files
pattern.split	Pattern to find and remove to create file name; currently set to ".rda"
min.signal.dur	The minimum duration (s) sound events must be to be considered sound events
max.sound.event.dur	The maximum duration (s) sound events must be to be considered sound events
wav.output	Logical; output wave file of sound events?
output.dir	Specified output directory; set to current working directory
swift.time	If file name is in structure recorder_YYYYMMDD_HHMMSS can subset files based on specific times
time.start	Time recordings start (hour)
time.stop	Time recordings stop (hour)
write.table.output	Logical; write Raven selection tables to output directory
verbose	Logical; print out steps
random.sample	If a random subset of files in a directory are desired specify a value, otherwise 'NA'
output	Either 'spectro', 'table' or 'wav'
