In tatters/soundgen: Sound Synthesis and Acoustic Analysis

Find bursts

Description

Internal soundgen function.

Usage

findBursts(
  ampl,
  step,
  windowLength,
  interburst,
  burstThres,
  peakToTrough,
  troughLocation = "either",
  scale = c("dB", "linear")[2]
)

Arguments

ampl	downsampled amplitude envelope
step	time difference between two points in the envelope (ms)
windowLength	length of FFT window, ms
interburst	minimum time between two consecutive bursts (ms). Defaults to the average detected (syllable + pause) / 2
peakToTrough	to qualify as a burst, a local maximum has to be at least peakToTrough dB above the left and/or right local trough(s) (controlled by troughLocation) over the analysis window (controlled by interburst). Defaults to SNR + 3 dB
troughLocation	should local maxima be compared to the trough on the left and/or right of it? Values: 'left', 'right', 'both', 'either'

Details

Called by segment.

Value

Returns a dataframe with timing of bursts
