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.
