multi_band_chimera: multi_band_chimera

In abeith/chimeRa: Create Auditory Chimeras with R

Description

multi_band_chimera Synthesize pair of multi-band "auditory chimeras" by dividing each signal into frequency bands, then interchanging envelope and fine structure in each band using Hilbert transforms.

Usage

multi_band_chimera(x1, x2, f = 1, cutoffs, fb = NULL, refilter = 0)

Arguments

x1, x2	original signals
f	sampling rate in Hz
cutoffs	band cutoff frequencies
fb	filter banks. Not required if cutoffs are specified
refilter	set to 1 to filter again after exchange operation (default 0)

Value

a list of two auditory chimeras. The first has envelope of x1 and the fine structure of x2 and the second has the envelope of x2 and the fine structure of x1
