normalize {tuneR}R Documentation

Rescale the range of values

Description

Centering and rescaling the waveform of a Wave object to either [-1,1], [0, 254], or [-32767, 32767].

Usage

normalize(object, unit = c("1", "8", "16", "0"), center = TRUE, level = 1)

Arguments

object Object of class Wave.
unit Unit to rescale to. "1" (default) for rescaling to real values in [-1,1], "8" (i.e. 8-bit) for rescaling to integers in [0, 254], "16" (i.e. 16-bit) for rescaling to integers in [-32767, 32767], and "0" for not rescaling (hence only centering, if center=TRUE).
center If TRUE (default), values are centered around 0 (or 127, if unit="8").
level Maximal percentage of the amplitude used for normalizing (default is 1).

Value

An object of class Wave.
