=====Usage:=====

<code>MULACRTALOG <var>L</var> <var>D</var> <var>WFUNC</var> <var>WTYPE</var> <var>X1</var> .. <var>X4</var> <var>REF</var> <var>AVR</var> OUT <var>A1</var> .. <var>A4</var> <var>Y1</var> .. <var>Y4</var></code>

=====Inputs:=====

;<var>L</var>

:The frame length in samples (number)

;<var>D</var>

:The hop size in samples (number), where <var>D</var> <code><=</code> <var>L</var>.

;<var>WFUNC</var>

:The window function (string). See <code>[[Programmer Guide/SPU Reference/WINDOW - signal window function|WINDOW]]</code> for details.

;<var>WTYPE</var>

:The window type. The following values are supported:

:<code>0</code> - dual

:<code>1</code> - tight

;<var>A1-4</var>

:The input signals (vector) with length <var>D</var>

;<var>REF</var>

:The reference amplitude for dB conversion

;<var>AVR</var>

:The exponential averaging factor (<code>0<=</code><var>AVR</var><code><=1</code>).

=====Outputs:=====

;<var>A1-4</var>

:The log. amplitude spectrum (vector)

;<var>Y1-4</var>

:The reconstructed signals (overlap-add) used for the spectrum computation (vector) with length <var>L</var>

=====Function:=====

Gabor analysis for frame multipliers, optimized for real-time / stereo. This atom is used to compute the spectra displayed by the S_TOOLS-STx script ReTiSiMo.

=====Notes:=====

Averaging: <code>A[i,t] = A[i,t-1]*sqrt(</code><var>AVR</var><code>) + spectrum[i,t]*(1-sqrt(</code><var>AVR</var><code>))</code>
