====MUXIN - input signal pre-processor====

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

<code>MUXIN <var>SEL</var> <var>L</var> <var>A</var> <var>B</var> <var>PAR</var> <var>SR</var> OUT <var>A</var> <var>B</var> <var>X</var> <var>Y</var> <var>LX</var> <var>LY</var> <var>PLX</var> <var>PLY</var></code>

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

;<var>SEL</var>

:The X/Y signal selection (number)

;<var>L</var>

:The frame length (number)

;<var>A,B</var>

:The input signals A, B (vector)

;<var>PAR</var>

:The processing parameters (vector). See the [[Programmer Guide/SPU Reference/Pre/Post-processing and ppm-evaluation used by MUXIn and MUXOUT|pre/post processing table notes]] for details.

;<var>SR</var>

:The sampling rate in Hz (number)

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

;<var>A,B</var>

:The pre-processed input signals A, B

;<var>X,Y</var>

:The signals selected by <var>SEL</var>

;<var>LX</var>

:The level <var>X</var> (number) in dB

;<var>LY</var>

:The level <var>Y</var> (number) in dB

;<var>PLX</var>

:The peak level <var>X</var> (number) in dB

;<var>PLY</var>

:The peak level <var>Y</var> (number) in dB

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

Pre-processor, multiplexer and level-meter for input signals.

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

Pre-processing is applied to A and B before selection.

The peak level outputs <var>PLX</var> and <var>PLY</var> are the overall maximum values of <var>PX</var> and <var>PY</var>.

To reset the peak values, use the reset value of the parameter table <var>PAR</var>.
