getMelSpec: Mel-transformed spectrum

In tatters/soundgen_beta: Parametric Voice Synthesis

Description

Internal soundgen function

Usage

getMelSpec(s, samplingRate = NULL, windowLength = 40, overlap = 50,
  step = NULL, throwaway = -120, maxFreq = NULL, plot = FALSE)

Arguments

s	input sound (path to a .wav file or numeric vector)
samplingRate	sampling rate of target (only needed if target is a numeric vector, rather than a .wav file)
windowLength	length of FFT window, ms
overlap	overlap between successive FFT frames, %
step	you can override overlap by specifying FFT step, ms
throwaway	parts of the spectra quieter than throwaway dB are not compared
maxFreq	parts of the spectra above maxFreq Hz are not compared
plot	if TRUE, plots the spectrum

Details

Takes a .wav file or a waveform as numeric vector + samplingRate and returns mel-transformed spectrum (auditory spectrum). Calls melfcc. See matchPars.
