#### 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.
