Internal soundgen function
getRough(m, roughRange, colNames = NULL)
Returns roughness in percent.
numeric matrix of non-negative values with colnames giving temporal modulation frequency
the range of temporal modulation frequencies that constitute the "roughness" zone, Hz
numeric vector with frequencies corresponding to columns
Helper function for calculating roughness - the proportion of energy / amplitude in the roughness range
m = modulationSpectrum(soundgen(), samplingRate = 16000)$original soundgen:::getRough(m, roughRange = c(30, Inf))
