Calculates the absolute amplitude envelope

Description

Calculates the absolute amplitude envelope

Usage

envelope(x, ssmooth = 0)

Arguments

x	Numeric vector with amplitude values. Required.
ssmooth	Numeric vector of length 1 indicating the size of the sliding window use to smooth envelopes. Default is 0 (no smoothing).

Details

The function calculates the absolute amplitude envelope of an amplitude vector using compiled C code which is usually several times faster.

Value

An amplitude envelope.
