Internal soundgen function
getMelSpec(s, samplingRate = NULL, windowLength = 40, overlap = 50,
step = NULL, dynamicRange = 80, maxFreq = NULL, plot = FALSE)
input sound (path to a .wav file or numeric vector)
sampling rate of target
(only needed if target is
a numeric vector, rather than a .wav file)
length of FFT window, ms
overlap between successive FFT frames, %
you can override overlap
by specifying FFT step, ms
parts of the spectra quieter than -dynamicRange
dB
are not compared
parts of the spectra above maxFreq
Hz are not compared
if TRUE, plots the spectrum
Takes a .wav file or a waveform as numeric vector + samplingRate and returns
mel-transformed spectrum (auditory spectrum). Calls
