# SHAPE_EQCOMP_SIDECHAIN_MODE

> SHAPE_EQCOMP_SIDECHAIN_MODE

Sidechain modes.

## Syntax

```cpp theme={null}
enum SHAPE_EQCOMP_SIDECHAIN_MODE    
{  
    SHAPE_EQCOMP_SIDECHAIN_MODE_NORMAL,  
    SHAPE_EQCOMP_SIDECHAIN_MODE_INTERNAL,  
    SHAPE_EQCOMP_SIDECHAIN_MODE_EXTERNAL  
}  
```

## Constants

| Constant | Description |
| - | - |
| SHAPE\_EQCOMP\_SIDECHAIN\_MODE\_NORMAL | Normal mode. |
| SHAPE\_EQCOMP\_SIDECHAIN\_MODE\_INTERNAL | Internal mode. |
| SHAPE\_EQCOMP\_SIDECHAIN\_MODE\_EXTERNAL | External mode. |

## Remarks

This enumeration is used in the [GetShapeEqCompSidechainMode](https://docs.xbox.com/reference/audio/shapeeqcompcontext/functions/getshapeeqcompsidechainmode.md) and [SetShapeEqCompSidechainMode](https://docs.xbox.com/reference/audio/shapeeqcompcontext/functions/setshapeeqcompsidechainmode.md) functions.

The EQ/Compressor-Expander block takes input from one or two mix buffers:

* One input is the audio signal to be processed.
* The second input, called *sidechain*, is the optional control signal used to determine the audio compression.

The processing of each of the modes is shown in the following diagram.

**Normal, Internal, and External modes.**\\
