MULACRTA

Usage:

MULACRTA L D WFUNC WTYPE X1 X2 ATYPE OUT A1 P1 A2 P2

Inputs:
L
The frame length in samples (number)
D
The hop size in samples (number). D <= L
WFUNC
The window function (string). See the SPAtom WINDOW for details.
WTYPE
The window type (string). The following values are allowed:
0 - dual
1 - tight
X1, X2
The input signals (vector). The length must be equal to D. X2 is optional.
ATYPE
The amplitude type (number). The following values are allowed:
0 - linear
1 - power
Outputs:
A1, A2
The amplitude spectrum (vector) of X1/X2. See ATYPE.
P1, P2
The phase spectrum of X1/X2 (vector). Note that this is unlocked.
Function:

A Gabor analysis for frame multipliers, optimized for real-time and stereo.
