MUXIN

MUXIN - input signal pre-processor

Usage:

MUXIN SEL L A B PAR SR OUT A B X Y LX LY PLX PLY

Inputs:

SEL

The X/Y signal selection (number)

L

The frame length (number)

A,B

The input signals A, B (vector)

PAR

The processing parameters (vector). See the pre/post processing table notes for details.

SR

The sampling rate in Hz (number)

Outputs:

A,B

The pre-processed input signals A, B

X,Y

The signals selected by SEL

LX

The level X (number) in dB

LY

The level Y (number) in dB

PLX

The peak level X (number) in dB

PLY

The peak level Y (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 PLX and PLY are the overall maximum values of PX and PY.

To reset the peak values, use the reset value of the parameter table PAR.

X/Y Selection:

SEL	X	Y	Description
0	A	B	mono A
1	B	B	mono B
2	A+B	A+B	mono sum
3	A-B	A-B	mono difference
4	A	B	stereo
5	B	A	stereo reverse
6	A+B	A-B	stereo sum/difference
