MULACRTA

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.
