extract_envelope: extract_envelope

In abeith/chimeRa: Create Auditory Chimeras with R

Description

extract_envelope Extract amplitude envelope of a signal.

Usage

extract_envelope(x, f = 1, cutoffs, complex = FALSE)

Arguments

x	signal
f	sampling rate in Hz
cutoffs	band cutoff frequencies
complex	if TRUE returns envelope and fine stucture as a complex valued vector

Value

a list of amplitude envelopes for the specified cutoffs, or a vector if only two cutoffs are provided

Source
