# AuMakeElementMultiplyConstant(3x)

initialize a MultiplyConstant element

## Name

**AuMakeElementMultiplyConstant** - initialize a MultiplyConstant element

## Synopsis

\#include \<audio/audiolib.h\>

**AuMakeElementMultiplyConstant**(*element*, *input*, *constant*)\
\
     **AuElement** \**element*; /\* **RETURN** \*/\
\
     unsigned short *input*;\
\
     **AuFixedPoint** *constant*;

## Arguments

- *element*

  Returns the initialized element.

- *input*

  Specifies the index of the element to supply the audio data for this element.

- *constant*

  Specifies the fixed point value that each sample from the input will be multiplied by. Fixed point values can be constructed with **AuFixedPointFromSum** and **AuFixedPointFromFraction**.

## Description

**AuMakeElementMultiplyConstant** sets the *type* of *element* to **AuElementTypeMultiplyConstant** and initializes the *multiplyconstant* member of *element* with the remaining arguments.

**AuMakeElementMultiplyConstant** is implemented as a macro.
